}Get the current docs version
Returns the current API contract version (api_version), the versioning and deprecation policy, and the content-hash version of the Laso Finance agent docs (SKILL.md, openapi.json, llms.txt, llms-full.txt, ai-plugin.json). Free, no auth or payment header.
Agents aggressively cache these docs, so use this to detect a stale cache: if the docs_version you last saw differs from the value returned here, refetch the docs. Every API response also carries this value in the X-Laso-Docs-Version response header, alongside X-Laso-Docs-Manifest, which points at the authoritative freshness beacon at https://laso.finance/.well-known/docs-version.json.
This route is also the status target of the API catalog at https://laso.finance/.well-known/api-catalog (RFC 9727), which every response advertises via a Link header with rel="api-catalog".

}Response
Current docs version
12-character content hash of the agent docs. Changes only when the docs change.
Version of the API contract itself (this description's info.version). Moves only on a breaking change, unlike docs_version. Also sent on every response as X-Laso-Api-Version.
The versioning and deprecation policy in machine-readable form: which header carries the version, what counts as an additive versus a breaking change, and how a retirement is signalled.
URL of the authoritative freshness beacon, served with no-cache.
URL of the RFC 9727 API catalog (application/linkset+json) indexing the OpenAPI description, the agent docs, and this status route.
Per-file entries, each with a url and a stable sha256 content identifier. Compare against the values you last saw to tell which file changed.
