Technical details
Endpoint
GEThttps://x402helper.xyz/89e509/docs/snippet?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to programmatically retrieve package documentation or README snippets from npm, PyPI, crates.io, or GitHub without scraping, and is operating in an x402-enabled micropayment context. It is especially useful for agents that need to answer developer questions about library usage, API signatures, or specific topics within a package's documentation at low cost per call.
Side effects
- Package not found in the specified ecosystem — returns success: false
- Invalid ecosystem value — returns validation error
- Payment not provided or insufficient — returns HTTP 402 before content is served
- Topic or symbol not found in README — may return empty or partial result
- Version pinned does not exist — returns not found error
