Documentación

readfetch

Web reading for AI agents — text, maps, rendered Markdown, raw HTTP, PDFs, sections, diffs, screenshots, search, and bounded crawl. Pay per call in USDC on Base via x402. No API key; you pay only when content is delivered (billed: true).

Live service: https://readfetch.com

This repository is documentation and discovery links only. The running service and its implementation are not open source.

Clients & integrations (app code)

Official packages (0.1.11+) — all published routes, x402 signing, call() / quote(), feedback and claims helpers:

pip install readfetch-client          # Python → github.com/readfetch/client-py
npm install @readfetch/client         # Node   → github.com/readfetch/client-js

MCP hosts (Cursor, Claude Desktop, …) — most cannot sign x402 on the remote MCP URL. Use the stdio proxy:

npx -y @readfetch/mcp-x402-proxy@0.1.11

Copy-paste host configs: HOSTS.md. Full client + MCP guide: INTEGRATIONS.md.

Package	npm / PyPI	GitHub
`@readfetch/client`	npm	client-js
`readfetch-client`	PyPI	client-py
`@readfetch/mcp-x402-proxy`	npm	mcp-x402-proxy

Agents (drop-in): AGENTS.md · CLAUDE.md

Start here (free)

curl -sS -X POST https://readfetch.com/v1/probe \
  -H 'content-type: application/json' \
  -d '{"url":"https://example.com"}'

/v1/probe is free: metadata plus an optional preview (~400 characters of /v1/text extraction when HTML and not a bot wall) before you pay.

Pay and call (curl)

POST /v1/probe (free) — then /v1/text or /v1/scrape from the result.
On 402, read the quote in the body and PAYMENT-REQUIRED header.
Sign the USDC authorization (x402 v2), retry with PAYMENT-SIGNATURE.

Prefer clients over hand-rolled 402: INTEGRATIONS.md.

Beta feedback

After a confusing call, agents should POST /v1/feedback with the X-Request-Id from that response (readfetch_feedback over MCP). Categories: integration, docs, site, other.

Paid delivery disputes use POST /v1/claims with the RECEIPT header and signature — not feedback. See readfetch.com/docs#feedback.
