How this service works
Machine-payable x402 utilities for hashing, Base64, UUID generation, unit and timezone conversion, realtime crypto market data, webpage/document extraction, URL-to-Markdown, metadata, RAG ingestion and deterministic website change detection.
Output
A structured JSON list of all hyperlinks found in the provided HTML, including href values and anchor text. If a base_url is provided, relative URLs are resolved to absolute. The response covers navigation links, inline links, and any other anchor elements present in the document.
Example use cases
Crawl seed link discovery
“I've fetched the homepage HTML of docs.example.com — extract every link from it so I can queue them for my site crawler.”
RAG pipeline link ingestion
“Pull all the URLs out of this HTML blog post so I can add them to my knowledge graph for retrieval-augmented generation.”
Outbound link audit
“I have the raw HTML for our company's about page — list every hyperlink (with anchor text) so I can audit where we're linking externally.”

Endpoint
POSThttps://x402-gateway-production-1f21.up.railway.app/html/links?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic extraction of all hyperlinks from a known HTML string — especially in machine-payable, agent-driven pipelines where you already have the raw HTML and want structured link output without spinning up a headless browser. It is ideal for crawling seed discovery, RAG pipeline enrichment, or auditing outbound links from pre-fetched pages.
Side effects
- Missing 'html' field in body causes validation error
- HTML string exceeding 500,000 characters is rejected
- Malformed or non-HTML content may result in empty link list
- base_url misconfiguration may produce incorrectly resolved URLs
- Payment failure via x402 protocol returns 402 status before processing
