How this service works
Fetch a public HTTP(S) URL and return status, final URL, title, meta description, canonical URL, Open Graph fields, and a short text sample. This deterministic endpoint does not call an upstream model. Pay up to $0.001 per request with x402 USDC on Base. Public paid calls are limited to 1500 input characters and 128 output tokens.
Output
A JSON object with ok status, tool name ('urlMetadata'), a human-readable summary of the URL's structured metadata, and a fetchedAt timestamp. May include title, description, Open Graph tags, and other page-level metadata fields extracted from the target URL.
Example use cases
Example prompt
“Can you fetch the metadata for https://example.com/some-article — grab the title, description, and any structured info from the page?”
Technical details
Endpoint
GEThttps://gpt55.558686.xyz/v1/tools/url-metadataWhen to prefer
Use this endpoint when you need lightweight, structured metadata extraction from a URL (title, description, OG tags) without full page scraping. Best suited for single-URL lookups at very low cost ($0.0001 USDC). Prefer this over full scraping tools when you only need page-level signals, not body content. The x402 micropayment model means no subscription is needed.
Side effects
- URL is unreachable or returns a non-200 status — ok:false with error details
- URL exceeds max_bytes limit and content is truncated or rejected
- timeout_ms exceeded if remote server is slow — timeout error returned
- Too many redirects if page has redirect chains beyond max_redirects
- Invalid or malformed URL input — schema validation error
- Payment failure via x402 — 402 response before endpoint is reached
