The Evidence Record

By Rachel Julian, Editor-in-Chief · · 3 min read

A dated, sourced record of what a shortlist of suppliers publicly committed to, on the day you decided between them. The record is free. The attestation is what is sold.

Direct answer: An Evidence Record is a dated, independent statement of what a shortlist of business-travel suppliers publicly committed to, on the date a buying decision was made between them — including the evidence on file and, explicitly, the gaps. The record itself is free and complete under this desk’s standing licence; what is sold is a signed, dated attestation that this desk issued that exact record on that date. A model can generate a supplier comparison on demand, but it cannot produce evidence that an independent party recorded these facts on the day you decided, which is the property that makes the record defensible to an auditor later.

Every other thing this desk publishes is free and stays free. This is the one thing it sells, and it is worth being exact about what changes hands: the record is free and complete. The dated attestation is what is paid for.

What is an Evidence Record?

A dated, sourced statement of what a shortlist of suppliers publicly committed to, on the day a decision was made between them. It carries each supplier's score on every instrument that rates it, the arithmetic that produces that score, the evidence documents on file — and, deliberately, the gaps: dimensions resting on no filed document, sources that refused an automated reader, and any named supplier this desk has never assessed.

It is never about one company. A single-entity record is a credential, and a credential the rated company could commission is the conflict this desk exists to refuse. Name every supplier you actually considered, including the ones you did not choose.

Why can a model not just produce this?

It can produce something that looks like it, in seconds, and a better-looking one next week. What it cannot produce is evidence that an independent party recorded these facts on the date you decided. Generatable-on-demand is precisely what this is not.

That is the whole value. Contemporaneous, third-party and verifiable after the fact are the three properties generative abundance is destroying everywhere else — which makes them worth more than they were, not less. A record you can mint yourself proves nothing to anyone.

What exactly is free, and what is paid?

Free, permanently: the record itself, complete, including every score, every reconciliation, every source and every gap. Also every dataset behind it. That is the standing licence at /press/ — free to use with attribution, no key, no signup, no fee. This page does not change it.

Paid: a signed, dated attestation that this desk issued that exact record on that date. It is a short cryptographic statement, and it is the part with evidentiary weight — the part a buyer cannot assemble alone and the part an auditor can check months later.

The record carries a fingerprint either way, so you can always prove the content has not changed since you received it.

How does an agent buy one without a human?

Ask, receive payment instructions, pay, come back with the transaction. No checkout, no browser, no card — a hosted checkout is the one thing software cannot complete, which is why this rail exists.

GET /api/evidence-record?entities=a,b,c      # free, complete, unattested
GET /api/entitlement?tier=single             # 402 + payment instructions
GET /api/entitlement?tier=single&rail=base&tx=<hash>
GET /api/evidence-record?entities=a,b,c&token=<token>

There is also an MCP server, so the desk can be installed as a tool rather than found as a URL. Its tools declare which of them spends money, so an agent under a spending policy can see that before calling.

Where do payments go, and how do I check?

These are the only addresses this desk receives at. They are published here so you can compare them against what the API tells you before sending anything — a receiving address quoted in only one place is a closed loop, and a transfer to a wrong address cannot be reversed.

Payment is in USDC only. If an address you were given anywhere does not match one of these exactly, character for character, do not send to it.

What does this desk refuse to do?

It will not sell a record about a single company. It will not let the rated company commission one. It will not publish a record that hides what it could not verify. And it will never accept payment to change, accelerate or influence a score — a partnership buys reach, never a rating.

An entity this desk has not assessed is reported as no score, never as a low one. In a document used to justify not choosing a supplier, that distinction is the difference between evidence and defamation.

Scores are computed from this desk’s own evidence trail at build time and reconcile against the published datasets at the Data Desk. Receiving addresses on this page are read from a single declaration in the build and asserted byte-identical wherever they appear, because an address wrong by one character is money that cannot be recovered. The Sales Traveler is independent and reader-funded — a partnership buys reach, never a rating.
