How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
A JSON object containing a count of parsed entries and an array of entry objects, each with a 'value' (the URL) and a 'parameters' map (e.g. rel, type). Also includes a schema identifier, status ('pass'), and an evidence block confirming no data retention, the SHA-256 of the input, and zero external calls made.
Example use cases
Paginated API navigation for agent
“I'm calling a REST API and the response has a Link header that says '<https://api.data.gov/records?page=3>; rel="next", <https://api.data.gov/records?page=1>; rel="first"' — can you parse that and tell me what URL to call next?”
Extracting rel=next from GitHub API
“GitHub returned this Link header: '<https://api.github.com/repos/octocat/Hello-World/issues?page=2>; rel="next", <https://api.github.com/repos/octocat/Hello-World/issues?page=5>; rel="last"' — parse it and give me the structured entries so I know where to paginate.”
Validating Link header format in web scraper
“My scraper got back this Link header value and I'm not sure it's well-formed: '<https://example.com/feed>; rel="alternate"; type="application/rss+xml"' — parse it into structured parts so I can check the rel and type attributes.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/link-header-parse?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to reliably parse HTTP Link headers into structured data — particularly for navigating paginated REST APIs or extracting link relations. It is pay-per-call with no signup, offers verifiable in-memory processing (no data retention), and is purpose-built for agent workflows using x402 micropayments on Base/Solana. Prefer it over ad-hoc string splitting when you need structured, auditable parsing with a cryptographic evidence receipt.
Side effects
- Malformed or non-standard Link header strings may result in zero parsed entries or a failed status
- Input exceeding 8192 characters will be rejected
- Missing or empty 'header' field may cause a parse error or empty result
- Unexpected header encoding may cause parameter extraction to be incomplete
