+- **`inspect` is the source of truth for price**: per call (`base_price`), per million tokens (`input_per_million` / `output_per_million`), or a `formula`.
+- **Data APIs have a daily free quota** (search, social, scraping, e-commerce, finance): every organization gets **100 free calls per UTC day, shared across all eligible data APIs**. Eligible tools show `pricing.free_quota` in `inspect`; `sandbase_account` (`sandbase balance --json`) shows today's allowance as `free_api_quota` (`daily_limit`, `used_today`, `remaining`, `resets_at`). Each eligible data API call counts toward the 100, whichever tool it hits. After the quota is used up, calls keep working and are **billed per call** at the price `inspect` shows; they are not blocked. A zero-balance organization can still use its free calls.
+- Models (LLM, image, video, audio) are always billed. Discovery, inspection, run status, balance, and `upload` are never billed.
+- Read the price with `inspect` before running instead of guessing what a call costs.
+- When a tool is billed **per result**, limits often apply **per query**: three search terms with `limit: 10` can return 30 results. Pass one search term per call and start with small limits (5–10).
+- Check `sandbase_account` before a batch of calls (balance, plus `free_api_quota.remaining` for data APIs: a batch larger than the remaining free calls is billed for the rest), and report cost when the user cares about budget (`cost` appears on `sandbase_run_get` and `sandbase_runs`).
 - Never re-run a slow tool just because it is still running; poll it.
 - A key can carry a **spending limit** set in the Dashboard. When it is reached, calls fail with "spending limit" until the user raises or removes it; topping up does not help.
