Conversation
Serply is a Google SERP API, so it joins tavily and brave as a value for web_search_provider rather than needing a SearXNG-shaped service in front of it. One function, mapping the query onto its native request and the answer back onto the hits WebSearchBackend already reads. Two things differ from the providers next to it. Serply reads num as an approximate bound on one SERP page instead of a count: num=20 answers with the same page as num=10, and a page can come back holding one row more than was asked for, so the request is clamped to the page size and the answer trimmed to it. And it spells recency as Google's own tbs window, so the shared time_range vocabulary maps onto qdr:d through qdr:y.
WalkthroughThe pull request adds Serply as a web-search provider. It updates configuration and documentation, implements Serply request and result mapping, and adds unit tests for authentication, limits, time ranges, and malformed responses. ChangesSerply web search support

Description
Otari can already call a licensed search API in-process instead of running a SearXNG-shaped service in front of it, and ships Tavily and Brave that way. This adds Serply as a third choice: set
web_search_provider: serplyandweb_search_provider_api_key, andotari_web_searchsearches Google's index through it. Nothing changes for a deployment that names a different provider or none.Serply is a Google SERP API, so it slots into the same one-function-per-provider shape as the two already there. Two things about it differ from its neighbors and are handled in the function:
numas an approximate bound on one page of results, not a count.num=20answers with the same page asnum=10, and a page can come back holding one row more than was asked for. So the request is clamped to the page size and the answer is trimmed to what the caller asked for, which a provider that returns at most what it was asked for does not need. Without the trim,web_search_max_resultswould be a number the model-facing result block is allowed to exceed.tbswindow, so the sametime_rangevocabulary Tavily and Brave take maps ontoqdr:dthroughqdr:yrather than onto a spelling of its own. A storedprovider_optionskeeps filtering by recency when a deployment switches provider.Like Brave, it returns snippets rather than page text, so
extracted_contentis left unset and the caller does its own fetch-and-extract pass.provider_optionsis whitelisted the same way: onlymax_resultsandtime_rangereach the request, so a workspace cannot set a Serply request field the deployment never chose, and the endpoint is a module constant that no option can redirect.One thing I found while testing that you may have an opinion on. For some queries Serply folds the local pack into
resultsas a row that calls itselforganicbut links togoogle.com/searchviewer/...rather than to a site, while theplaceskey stays empty. The fetch-and-extract pass then spends a fetch on it and gets nothing useful. I left it alone, since the row is what the provider returned and neither of the other two functions filters what it is given, and noted it in the docstring instead. Happy to drop those rows if you would rather the function did.This is an Otari change rather than an any-llm one: it is the
otari_web_searchtool loop, not a provider model call.How to test it locally
Five new tests cover the mapping, the page trim, the clamp, the recency window, and a missing
resultslist. The HTTP layer is mocked, so they need no key and no network.To see it end to end, set
web_search_provider: serplyandweb_search_provider_api_keyinconfig.yml, then send anotari_web_searchrequest as docs/tools.md describes.I also ran the function against the live API while writing it, which is where the two quirks above come from:
That last line is the sanitization the module already does: a real 401 body reads
{"detail":"Invalid API key"}, and none of it reaches the message.PR Type
Relevant issues
None. Happy to open one if you would rather discuss a third provider before the code.

Any additional AI details you'd like to share:
The function and its tests were written against the existing Tavily and Brave functions in the same module. The response mapping, the page bound and the recency window were each checked against the live Serply API before the code was written, and the numbers quoted above are from those runs.
Disclosure: I work with Serply. Happy to adjust scope or naming, or to drop this entirely if a third provider is not a direction you want.
Summary
Added Serply as a supported web-search provider for
otari_web_search.Deployments can select
web_search_provider: serplyand useweb_search_provider_api_key. Serply results return snippets, which preserves the existing fetch-and-extract flow.Technical notes
