📝 WalkthroughWalkthroughAdds the ChangesStarton provider integration
Priority: ➖ Normal — Schedule the Starton integration because it adds a broad Web3 provider covering wallets, smart contracts, transactions, authentication, schemas, and documentation without elevated external urgency. Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This adds Starton wallet, contract, and transaction operations, but the package test command may not execute its ESM test configuration correctly, and the published API examples fail when copied because required inputs are omitted. These issues should be corrected before merge so validation coverage is runnable and users receive functional integration guidance. Sequence Diagram(s)sequenceDiagram

This endpoint uses makeStartonRequest<StartonWallet>, which only supplies a compile-time type, and returns the raw API response. Corsair's runtime binding also returns endpoint results without applying endpointSchemas, which are used for schema inspection rather than runtime parsing. A malformed or incompatible Starton response can therefore reach callers as a successfully typed value. The same issue affects the other wallet, smart-contract, and transaction endpoints. This violates the repository requirement that every endpoint validate its inputs and outputs with Zod.

ts-jest 29.4 ESM support experimental-vm-modules official documentation
💡 Result:
To use ECMAScript Modules (ESM) with ts-jest, you must execute the Jest runtime with the --experimental-vm-modules flag, as this remains a core requirement for Jest's experimental ESM support [1][2]. According to official ts-jest documentation, enabling ESM involves the following primary steps [1]: 1. Runtime Configuration: You must run your test command using node with the --experimental-vm-modules flag [1][3]. For example: node --experimental-vm-modules node_modules/jest/bin/jest.js If using Yarn, use: yarn node --experimental-vm-modules $(yarn bin jest) 2. tsconfig.json Configuration: You must configure the module option in your tsconfig.json to support ESM [1][3]. You can use either: - Hybrid module values (Node16, Node18, or NodeNext), which must be paired with "type": "module" in your package.json [1][4]. - ES module values (e.g., ES2022 or ESNext), which ts-jest recommends for full support of recent ESM features [1][3]. When using these, you should typically have isolatedModules: true enabled [1][5]. 3. Known Limitations: - Mocking ES modules is not yet supported in Jest [1][6]. - Jest does not yet automatically account for the "type": "module" field in package.json to switch into ESM mode; therefore, the explicit --experimental-vm-modules flag is mandatory [1][2]. For detailed configuration, including how to handle ESM imports from outside node_modules using moduleNameMapper or custom resolvers, refer to the official ts-jest ESM Support guide [1][3].

Start Jest with the required ESM runtime flag.
packages/starton/jest.config.cjs enables ts-jest ESM transforms, but the test script does not supply Node’s --experimental-vm-modules flag. Add the flag to the test runner. Without it, the Starton tests may fail to start.

…ion-safe Addresses both P1 findings from automated review on corsairdev#1598. Retry safety ------------ Corsair can replay a failed call at two independent layers: `corsair/http` retries internally on HTTP 429, and the endpoint binder re-invokes the whole endpoint whenever an error handler returns `maxRetries > 0`. Starton exposes no idempotency key, so replaying a write that broadcasts a transaction can deploy a second contract, execute a contract call twice, or repeat a value transfer. A 5xx is ambiguous in exactly this way: Starton may already have accepted the transaction before the response failed. Both layers are now shut for the three operations that create side effects (`wallet.create`, `smartContract.deployFromTemplate`, `smartContract.call`), while reads keep their retries. The classification lives in `idempotency.ts` and is asserted against the declared endpoint list so a rename cannot silently re-enable replay. Runtime response validation --------------------------- `endpointSchemas` feed Corsair's introspection layer (`zodToFormSchema`), not the binder — nothing was validating provider payloads, so a malformed Starton response reached callers as trustworthy typed data. Each endpoint now parses its response with the declared output schema before returning, matching the pattern already used by ~46 plugins. Also fixes four Biome failures (`noDelete`, import order, formatting) that would have failed `pnpm lint` in CI. Verified locally: 72 tests pass, tsc --noEmit clean, validate:plugins clean, biome clean, git diff --check clean. All six operations re-verified against the official Starton OpenAPI specification, including a field-level audit of required/optional across every request and response schema.

Both findings were fail-open defaults; both now default to not replaying. client.ts — `replayable` defaulted to `true`, so a write endpoint added later that forgot `replayable: false` would be replayed by `corsair/http` after a 429. The default is now derived from the HTTP method: GET replays, everything else does not. Explicit overrides still win, and `smartContract.read` now states `replayable: true` outright — it is a POST only because Starton takes the call arguments in a body, and it broadcasts nothing. error-handlers.ts — both retry paths only withheld retries when an ErrorContext happened to be present, so a missing context or an unrecognised operation fell through to retrying. The decision now runs off an explicit retry-safe allowlist (`RETRY_SAFE_OPERATIONS`), so an absent, renamed or unclassified operation is never replayed. Retry limits for verified-safe operations are unchanged (429 -> 5 with Retry-After, 5xx -> 3). Two existing tests asserted the old fail-open behaviour by calling the handlers without a context; they now pass a verified-safe operation, and the no-context case is asserted directly instead. A partition test proves every declared operation is classified exactly once, so a seventh operation cannot be added without a decision. Verified locally: 84 tests pass, tsc --noEmit clean, validate:plugins clean, biome clean, git diff --check clean.

Fetch standard redirect cross-origin custom request headers Authorization custom headers removed redirect
💡 Result:
Under the current Fetch Standard, user-agent-set Authorization headers are automatically removed from a request when it encounters a cross-origin redirect [1][2][3]. This behavior was introduced to improve security and privacy, preventing the unintended exposure of sensitive authentication credentials to third-party servers during a redirect chain [4][1][5]. Key details regarding this behavior include: Scope: This rule specifically applies to the 'Authorization' header when it has been explicitly set by the web developer (e.g., via the 'headers' option in a fetch call or setRequestHeader in XHR) [6][5]. Browser-managed authentication (such as credentials handled via HTTP authentication prompts or built-in cookie handling) is managed by different mechanisms and is also subject to domain-matching rules, but the change specifically targeted the developer-controlled Authorization header [4][6][5]. Mechanism: When a request is redirected to a different origin, the Fetch API strips the Authorization header from the new request sent to the destination URL [1][2]. This ensures that if a request is initiated to 'A', but redirected to 'B', the secret token intended for 'A' is not leaked to 'B' [1][5]. Exceptions and Limitations: - Same-origin redirects generally preserve the Authorization header [3]. - This behavior is a mandatory part of the modern Fetch Standard [7][8]. Browsers that have implemented this change (such as modern versions of Chrome, Firefox, and Safari) will enforce it consistently [5][3]. - Developers encountering issues with this behavior, such as in development environments where a request is redirected from a staging API to a local server, must ensure their endpoints do not trigger cross-origin redirects if the authentication context depends on that header [1][5]. For developers who previously relied on this behavior, the recommended approach is to ensure the initial request is made directly to the final destination URL, or to handle the redirect logic at the application level (e.g., by intercepting the 3xx response and making a new, authorized request to the target) rather than relying on the browser's automatic follow mechanism [9].

🌐 Web query:
site:fetch.spec.whatwg.org redirect x-api-key custom request header cross-origin redirect
💡 Result:
When a browser encounters a cross-origin redirect during a fetch request, custom request headers—such as a custom x-api-key—are typically stripped from the redirected request for security reasons [1][2]. The Fetch Standard dictates that when a request follows a redirect to a different origin, it must undergo a series of security checks to prevent the leakage of sensitive information or credentials [1][3]. Specifically, if the request is a CORS request (which is necessary to use non-safelisted custom headers), the browser will strip custom headers—those not included in the CORS-safelisted request-header list—from the redirected request if the new destination is considered cross-origin [1][2]. This behavior prevents the accidental exposure of authentication tokens or custom metadata to a third-party server that was not the intended target of the initial request [1]. If your application requires a custom header to be present on the final, redirected request, you must ensure that the redirect target is on the same origin or design your architecture to handle the authentication/authorization at the final endpoint without relying on headers being preserved across cross-origin redirects. If the redirect is under your control, you may also need to implement server-side logic to handle the initial request and redirect in a way that does not require the client to re-send sensitive headers across origin boundaries [1][3].

Node.js undici fetch cross-origin redirect custom x-api-key header forwarded
💡 Result:
When using undici's fetch or request with redirection enabled, custom headers like x-api-key are generally intended to be forwarded [1][2]. However, several factors can prevent them from being included in the redirected request, depending on the implementation version and configuration. 1. Security and Specification Compliance Undici follows the WHATWG Fetch standard [3]. By default, undici may strip sensitive or request-specific headers during cross-origin redirects to prevent credential leakage [1]. If your custom header is being stripped, verify whether it is being treated as a sensitive header by the redirect handler [1]. 2. Configuration and Header Stripping The redirect interceptor includes functionality to strip headers during redirects [4][1]. Ensure you are not using an interceptor configuration that explicitly removes the x-api-key header. You can inspect or modify this behavior using the stripHeadersOnRedirect or stripHeadersOnCrossOriginRedirect options when composing your dispatcher [4][1]. 3. Known Issues and Header Construction There are known historical issues regarding how custom headers are handled during redirects in undici [5][2]. - Header Object Type: Using new Headers() to define headers can sometimes cause issues where Object.keys() iteration fails to capture the headers properly during the redirect process [2]. Providing headers as a plain JavaScript object is generally more reliable in these scenarios [2]. - Version Regressions: Users have reported regressions in specific versions of undici where custom headers were inadvertently dropped [5]. If you are experiencing this, verify your environment's undici version and check for relevant GitHub issues [5]. Recommendation If your headers are missing: - Use a plain object for the headers option in fetch or request rather than a Headers instance [2]. - Configure a custom redirect interceptor if you need granular control over which headers are forwarded, allowing you to explicitly permit x-api-key during cross-origin redirects [4][1]. - Verify that your server's redirect response (the 3xx response) does not trigger security policies that strip the header before undici even processes the redirect [1].

Reject redirects before sending x-api-key.
makeStartonRequest delegates redirects to the runtime fetch implementation. Runtime behavior differs, and x-api-key can be forwarded by server-side implementations. Since the Starton client does not need redirects, set redirect: 'error' in RequestInit.

R4 (demo video): Starton's hosted API is currently offlineI could not produce the live working proof R4 asks for, and I don't want to paper over why.
What this means for R4: the rule exists so a human can see the integration working against the real third-party API. That verification genuinely cannot be performed right now, so I've left R4 failing rather than attaching a substitute recording to turn the check green. A video that doesn't show a successful live call would defeat the point of the rule. What is verified, all exiting 0 (see the updated Validation section):
I do have a 42-second recording of the read-only demo ( Question for maintainers: how would you like R4 handled for an integration whose upstream provider has gone offline after the issue was accepted? Options I see are holding the PR until/unless Starton returns, merging on the strength of the spec-conformance and test evidence with R4 waived, or closing #1496 as no-longer-applicable. Happy to follow whichever you prefer. |

…in docs Runtime input validation ------------------------ Outputs were already parsed, but nothing validated inputs. Corsair's endpoint binder does not apply `endpointSchemas` — they feed introspection (`zodToFormSchema`) only — so caller input reached Starton unchecked. In practice that meant `wallet.create` forwarded the caller's raw object as the POST body and `wallet.list` spread it into the query string, so unknown keys were sent verbatim to the provider, schema defaults such as `params: []` were never applied, and invalid arguments cost a network round trip before failing. Each endpoint now parses its input with the declared schema before issuing the request. Because `z.object()` strips unknown keys, this also keeps caller-supplied extras out of request bodies and query strings. This completes the repository rule that every endpoint validate both inputs and outputs with Zod; the output half shipped in 77e011e. Schema documentation -------------------- Input fields now carry `.describe()`, using the official OpenAPI wording where Starton provides it (network, signerWallet, templateId, params, speed, customGas, nonce, value, simulate, page, limit). Corsair's inspect layer reads these descriptions, so they flow into agent-facing tool schemas and the generated reference docs. 64 plugins already follow this convention; Starton had none. Each endpoint also gains a short JSDoc header naming its exact route. Generated reference docs ------------------------ `pnpm generate:docs --plugin=starton` output under `docs/plugins/starton/`, plus the nav entry in `docs/docs.json` — matching the 208 plugins that already ship generated docs. The `docs.json` change is the 8-line Starton group only; the generator's unrelated reformatting of the Overview block was reverted. Verified: 92 tests pass (8 new, covering rejection of missing/wrong-typed fields with zero requests issued, the pagination ceiling, unknown-key stripping from body and query, and default application), tsc --noEmit clean, build clean, validate:plugins clean, validate:docs clean, repo-wide `biome check .` clean across 7092 files, git diff --check clean.

Replace the non-runnable API examples.
Each example passes {} although the operation has required input fields. Copying these examples causes runtime validation to reject the call before any request. Generate minimal valid inputs for each operation.

Description
Adds a Corsair integration for the Starton Web3 API (
api.starton.com, REST v3).Closes #1496

Authentication
API key sent as the
x-api-keyheader, percomponents.securitySchemes.api-keyin the official spec. The key is never placed in a URL, query string or body, and
is asserted absent from thrown provider and transport errors.
Two engineering decisions worth reviewing
Retry safety. Starton exposes no idempotency key, and Corsair can replay a
call at two independent layers:
corsair/httpretries internally on HTTP 429,and the endpoint binder re-invokes the whole endpoint whenever an error handler
returns
maxRetries > 0. A 5xx is ambiguous — Starton may have accepted andbroadcast the transaction before the response failed — so replaying a write
could deploy a second contract or repeat a value transfer. Both layers are shut
for
wallet.create,smartContract.deployFromTemplateandsmartContract.call; reads keep their retries.replayabledefaults totruefor GET and
falsefor every other method, so a write endpoint added later issafe by default. The classification lives in
idempotency.tsas an explicitallowlist and is asserted to partition the declared operations exactly.
Runtime validation.
endpointSchemasfeed Corsair's introspection layer,not the binder, so each endpoint parses its own input and output. Malformed
provider responses surface as errors rather than being returned as trusted typed
data, and unknown caller keys are stripped rather than forwarded to Starton.
Validation
All exit 0, run off an iCloud-free checkout:
pnpm test— 92 passed, 2 skipped (live, credential-gated), 94 totaltsc --noEmit— cleanpnpm build— cleanpnpm run validate:plugins—[SUCCESS] All plugins passed structural validation!pnpm run validate:docs— cleanbiome check .— clean across 7092 filesgit diff --check— cleanAll six operations were verified against the official
starton-io/starton-openapi
specification — method, path, path/query parameters, request DTO, required
fields, response schema, error codes and security scheme — including a
field-level audit of required vs. optional across every request and response
schema.
Screenshots / Demos
A real ~42-second screen recording of the read-only
starton.wallet.listpathis attached below:
starton-demo-crop.mp4
It shows the test suite passing, then the actual Corsair integration
constructing and sending the request —
GET https://api.starton.com/v3/kms/walletwith
x-api-keyauthentication — and the real provider response.No successful live API response is claimed or fabricated. Starton's hosted
API currently returns HTTP 530 / Cloudflare 1016 ("Origin DNS error"), so
the recording documents the real integration behaviour and the current upstream
outage rather than a working live call.
app.starton.com(where an API keywould be generated) is also 530,
docs.starton.comreturns 402, andstarton.comdoes not respond at all, so no credential can be obtained either.Full probe output, and a question for maintainers on how you would like R4
handled for an integration whose upstream provider went offline after the issue
was accepted, are in
this comment.
Everything that does not depend on the provider being reachable is verified
above.
