[!TIP] The interesting part is not that it finds evidence. It is that you can check it. Every id in every answer resolves through GET /v1/evidence/{id}, and POST /v1/verify will re-resolve a set of claims against the corpus, ours or anybody else's. An id that does not resolve is a claim that was never real.

{
  "finding": "Sizing runs small, and buyers only discover it after delivery",
  "corroboration": { "records": 31, "channels": 5 },
  "receipts": ["rc_8f2a1", "rc_44b0e", "rc_91c37"],
  "confidence": "finding"
}

GET /v1/evidence/rc_8f2a1 returns the actual comment, its score, where it was posted, when, and its permalink. A customer of your customer can click a claim and read the human who said it.

The hosted API lives at https://quorum-api-j15n.onrender.com, on a free tier instance that sleeps when idle, so the first request after a quiet spell waits a few seconds for it to wake.

The hosted instance is keyed while the API is early. The API root says how to request a key, and always says which mode the instance you are talking to is in. The health endpoint needs no key, so you can check it is alive right now:

curl https://quorum-api-j15n.onrender.com/v1/healthz

Self hosting supports open mode or per key auth, quotas, tenancy and webhook secrets, all self served from GET /v1/usage.

[!NOTE] On Windows, the curl bundled with Git Bash uses the Schannel TLS stack, which refuses any HTTPS connection when it cannot reach the certificate revocation servers (CRYPT_E_REVOCATION_OFFLINE, common behind corporate proxies and VPNs). That is the network, not this API. Add --ssl-revoke-best-effort to the curl command, or call from WSL or PowerShell instead.

What it does

Voice of customer from public archives, competitor ads ranked by how long they have actually been running, and a video versus static verdict computed as arithmetic rather than opinion. It keeps everything it reads, so the second question about a market is nearly free and the archive can be asked about the past.

Key capabilities

• Receipts, not links. A stable id into a retained corpus, which resolves identically forever, including after the source deletes the original.
• **Corrob
