## Use it

- Paid, per call, no account: GET https://offweb.dev/fetch?url=<url> answers HTTP 402 (x402 v2, $0.005 USDC on Base); retry with PAYMENT-SIGNATURE.
- MCP, streamable HTTP: https://offweb.dev/mcp with tools fetch(url) and about(). 20 free fetches per client address per UTC day, then the paid route.
- Machine-readable: https://offweb.dev/capabilities (limits, receipt key, payment), https://offweb.dev/openapi.json.

## What you get back

JSON with source, retrieval (status, content_type, bytes, sha256, retrieved_at, tls_fingerprint), content (verbatim text),
and receipt: an Ed25519 signature over the source and retrieval blocks. The receipt says offweb fetched this URL at this
time and got these bytes. It says nothing about whether the bytes are true or lawful.

## Limits

text/* only, 1 MiB cap, 20 s timeout, 3 redirects, 1 request per second per host, Gemini robots.txt honoured.
No search, no Tor, no binary content, no crawling, no cache. Refusals are 4xx/5xx and never billed.
