Web pages your agent can quote: 1,000 full fetches a month free, no card, then $0.01 a page.
发布方自己的服务：Proof Holdings
远程 MCP 服务器，抓取公开网页并返回可引用的分段文本、哈希与凭据，提供免费预览额度。
Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。
把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体，或 SourceWeft 对话中。智能体会读取该服务器的安装指南，先向你展示发布者、端点和登录方式，经你同意后再把它添加到你的客户端。密钥不会写进任何命令。
阅读 https://sourceweft.com/mcp/io.github.equinoxaifinance-rgb%2Fproof-fetch/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。把它添加到你客户端的 mcpServers 配置中。

}Free check with a text preview (about the first 1,000 characters; short pages come back whole). Full text costs 1¢ a page either way: 500 pages for $5 by card, or $0.50 for 50 if your agent pays automatically through Stripe (the page it asked for, plus a key for 49 more).

This repository contains documentation, small client examples and a thin local stdio MCP client (server.mjs: npx github:equinoxaifinance-rgb/proof-fetch-docs, or docker build .) that forwards every tool call to https://prooffetch.steellantern.com/mcp; set PROOF_FETCH_KEY to send your key. It does not contain the extraction engine, a payment credential, or a way to obtain the paid paragraphs free.

The example makes no payment.This repository's documentation, discovery metadata and examples, including the n8n wrapper and guide in guides/n8n, are MIT licensed under the root LICENSE. The MIT licence does not cover the ProofFetch extraction engine or the hosted service at prooffetch.steellantern.com: their source is not in this repository and is not licensed or distributed here. Paid paragraphs, upstream material, credentials and account or payment rights keep their own terms.
skills/cited-web-evidence/SKILL.md teaches an agent when and how to use ProofFetch: preflight first, pay only with the user's approval, and cite paragraph IDs. Install it into Claude Code, Cursor, Codex or another skills-aware agent with npx skills add equinoxaifinance-rgb/proof-fetch-docs --skill cited-web-evidence.
Use Streamable HTTP at https://prooffetch.steellantern.com/mcp (the original https://proof-fetch-agent-api.neoaethel.workers.dev/mcp keeps working). In Claude Code: claude mcp add --transport http proof-fetch https://prooffetch.steellantern.com/mcp. Its free tools are proof_fetch_preflight and proof_fetch_offer. It also lists proof_fetch_evidence, which returns the paid text and needs a ProofFetch card-pack key sent as Authorization: Bearer <key>. MCP Registry manifest: server.json (io.github.equinoxaifinance-rgb/proof-fetch). The free tools never return the paid page text. Clients paying through Stripe MPP use POST /v1/evidence; each $0.50 payment returns the page plus callBundle.apiKey for 49 more.
Free preflight: fetch metadata, document statistics, content/raw hashes and deterministic prompt-injection indicators. Paid fulfillment adds paragraph IDs, text and a payment receipt. A hash identifies bytes; it does not certify that a source is true. An unflagged page is not a safety guarantee.
Supported: public HTML, XHTML, text and JSON, at most 1 MiB and five redirects. No login, cookies, caller headers, browser rendering or private-network destinations. Inspect the live offer for current limits before integration.

Check a public page (free)
Free: checks a public URL and returns fetchability, provenance, hashes, deterministic injection indicators and a free preview of the first 1,000 or so characters of text (short pages come back whole); not a safety guarantee. No payment or purchase. Example: {"url":"https://example.com/","maxChars":30000}.
url必填maxCharsShow the offer and prices
Returns the offer and request schema without buying. Full cited text: 1,000 free extractions with a free key (no card), then $0.01 a page either way: a 500-page card pack for $5, or $0.50 per Stripe MPP call, which returns the page plus an API key holding 49 more. Cited text uses POST /v1/evidence with a caller-generated idempotency key. Example arguments: {}.
无需输入参数。
Get cited page text (uses a key credit)
Fetch a public URL and return its cited, paragraph-addressable text with integrity hashes and a receipt. Uses one credit from a ProofFetch key, and only when extraction succeeds. Needs the key sent as the MCP request header Authorization: Bearer <key>: a free key holds 1,000 extractions (no card, POST /v1/keys/free or the ProofFetch home page); a paid key holds 500 for $5.00 (sold on the ProofFetch home page). Example: {"url":"https://example.com/"}.
