How this service works
Working code snippets for a library, matched to a topic. Give an ecosystem, package name and a topic or symbol and get the fenced code blocks from the README or docs whose language, code or nearest heading matches, each with a source citation and an honest truncated flag. Ideal for grounding a coding agent in real usage examples.
Output
Returns an array of fenced code blocks from the package's README or docs whose language, code, or nearest heading matches the requested topic or symbol. Each block includes the code content, the source URL/citation, the detected language, and an honest truncated flag indicating whether the block was cut off.
Example use cases
Example prompt
“Can you pull the code snippets from the coinbase/x402 GitHub repo's README that match 'authentication' — I need real working examples to ground my implementation.”
Technical details
Endpoint
GEThttps://api.agentstools.dev/docs/snippetWhen to prefer
Use this endpoint when you need to ground a coding agent in real, verified usage examples from a package's actual documentation rather than relying on training data that may be stale. Especially useful for pinning to a specific version, looking up niche symbols, or when hallucination risk on library APIs is high. Prefer this over generic web search when you want structured, citation-backed code blocks rather than raw HTML or prose.
Side effects
- Package not found in the specified ecosystem — returns an error or empty results
- Topic/symbol not found in any heading or code block — returns empty snippet array
- Invalid ecosystem value — returns a validation error
- Version not found or not yet indexed — returns an error or falls back to latest
- Rate limit or payment failure (x402) — returns 402 Payment Required
- Network timeout fetching upstream docs — returns a 5xx error
