It accepts a URL as a query parameter and returns a structured JSON response listing all internal and external links found on that page, along with counts for each category. The endpoint uses a dual-engine extraction system capable of handling JavaScript-rendered pages, so it works on modern SPAs and server-rendered sites alike.\n\nThis is an x402-gated GET endpoint priced at $0.01 USDC per call on the Base network. No API key or account signup is required — callers pay per request using the x402 payment protocol. Alternative access methods are also available: an MCP gateway at mcp.hugen.tokyo, a free API key with $0.05 credit via discovery.hugen.tokyo, or the `x402-pay` Python SDK for one-line access without a wallet.\n\nThe `/content/links` endpoint is one of five paid endpoints in the API suite, which also includes `/content/metadata`, `/content/extract`, `/content/summary`, and `/content/analyze`. The response schema is not formally documented in the OpenAPI spec, but the x402 challenge includes a sample response showing `internal` and `external` arrays of URL strings plus `internal_count` and `external_count` integer fields.","tags":[],"capabilities":["link-extraction","web-scraping","js-rendering","url-analysis","x402-payment","per-call-pricing","structured-json-response"],"categories":["search","web-scraping"],"synonyms":["link extractor","URL scraper","hyperlink extraction","web link parser","outbound link finder","internal link discovery","site link analysis","crawl links"],"warnings":["Response schema is not formally defined in the OpenAPI spec — the sample response is inferred from the x402 challenge payload","No dedicated documentation pages found (pricing, README, API pages all return 404)","No rate limit or usage quota information available"],"endpointUrl":"https://content.hugen.tokyo/content/links","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x29322Ea7EcB34aA6164cb2ddeB9CE650902E4f60","amount":"5000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300},{"asset":"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v","extra":{"feePayer":"Hc3sdEAsCGQcpgfivywog9uwtk8gUBUZgsxdME1EJy88"},"payTo":"4du4AfkjJEwch2zk3shkPJVZfyJHNDnNjEWC6AboaS5Z","amount":"5000","scheme":"exact","network":"solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp","maxTimeoutSeconds":300}]},"qualityScore":"0.650","qualityRationale":"The endpoint is live (402 challenge captured) with a clear OpenAPI spec and sample response embedded in the challenge.
