How this service works
Up-to-date docs for any npm, PyPI, crates or Go library: finds the project's own llms.txt and docs pages (or the latest release's README), keeps only the sections relevant to topic within a tokens budget, and returns them with sources and the current version. library is the package name; ecosystem defaults to npm. ?library=hono&topic=middleware&tokens=3000
Output
Returns a JSON object containing: markdown-formatted documentation content (with HTML comment source headers), the library's latest published version, the package ecosystem, a list of source URLs with their kind (llms.txt, docs-page, readme, etc.), an estimated token count, a truncation flag indicating if content was cut to fit the budget, a homepage URL, and a fetchedAt timestamp.
Example use cases
Coding agent using current Rust library docs
“Fetch the latest documentation for the serde crate on crates.io, focused on custom serialization, and keep it under 4000 tokens so I can use it while writing my Rust code.”
Python developer debugging auth flow
“Get me the up-to-date fastapi docs from PyPI on authentication and OAuth2, trimmed to 5000 tokens — I need to make sure I'm not using a stale API.”
Go developer exploring HTTP routing
“Pull the current docs for github.com/gin-gonic/gin on routing, from the Go ecosystem, and limit it to 3000 tokens with sources included.”
Technical details
Endpoint
GEThttps://aayatai.com/docs/lib?utm_source=zero.xyzWhen to prefer
Choose this endpoint when a coding agent needs fresh, authoritative documentation for a specific library rather than relying on potentially stale training data. It is especially valuable when working with rapidly-evolving packages where APIs change between versions, or when you need topic-scoped docs trimmed to fit an LLM context window. Prefer it over generic web search when you want structured, version-tagged markdown with explicit source attribution rather than raw HTML pages.
Side effects
- Library not found in the specified ecosystem — returns an error or empty content
- Topic too narrow with no matching documentation sections
- Token budget too small to return meaningful content (minimum 500)
- Documentation source unavailable or unreachable at crawl time
- Incorrect ecosystem specified for the library (e.g. npm instead of pypi)
- Rate limiting or payment failure via x402 protocol
