Receipts

Every citation an agent gives you, checked against the page it cites.

In our test, a model asked to answer 20 factual questions with a source and a verbatim quote gave 19 citations, and none of the 19 quotes was on the page it named. Receipts fetches the cited page, looks for the passage, and gives back a receipt you can re-read later.

This page is an open agentic website: its agent network, runtime and tools are public files, and any agent can call its citation checker as a public MCP server.

Receipts checked in this tab, newest first. Each receipt is also stored on the server and can be re-read at its link.

    Ask Receipts

    Paste a paragraph with sources, or a claim and a link. The assistant finds each quote-and-source pair, checks it on this page, and tells you which ones hold up.

    Your messages and this page's data go to the LLM in the settings below: a free demo model this site pays for (rate-limited), or your own provider and key. Cited pages are fetched by this site's server, not by your browser.

    Use Receipts from your own agentic website

    Receipts publishes two building blocks. Neither needs a key from you or a server of yours.

    1. The public MCP server

    Any agent, in a browser or on a server, can call verify_quote(url, quote) and get_receipt(id). CORS is open and no key is needed.

    {"url": "https://deploytest.theodoikenh.com/oaw-receipts/mcp", "tools": ["verify_quote", "get_receipt"]}

    An open agentic website lists it in an agent's tools as an MCP URL, so its own network can check citations before it answers.

    2. Public receipts

    Every check is stored and can be re-read by anyone at /receipt/<id>. An agent that answers with a citation can attach the receipt id, and the reader can verify it without trusting the agent.

    3. The agent network

    This page's network, receipts_desk, its manifest and runtime are plain static files. Copy them as a starting point for a fact-checking assistant on your own site.

    Public files: agent-manifest.json · receipts_desk.network.json · receipts_desk.hocon · agent-mcp.json · links.json
