# Paylyte Checked Official Record Retrieval

> Paylyte Checked Official Record Retrieval is a paid API for AI agents from api.paylyte.ai, paid per call via x402, $0.25/call, status unknown (last checked 2026-10-11).

Returns a cryptographically verified official record — including a source hash and Bitcoin timestamp — for a given catalogue record ID, enabling tamper-detection against any copy of the data.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability paylyte-checked-official-record-retrieval-2c14d087
```

Example prompt: Can you fetch the official checked record for nws_alerts_2026-08-30T18 and give me the source hash and Bitcoin stamp so I can verify my local copy hasn't been tampered with?

## When to prefer this

Choose this endpoint when you need a cryptographically trustworthy, Bitcoin-stamped attestation that a specific data record is authentic and untampered — particularly useful for verifying FRED series, NWS alerts, tweets, or model outputs against an official canonical source. Prefer this over generic checksums or unsigned hashes when you need an immutable, third-party-verifiable proof with an Agent Trust Score.

## Known failure modes

- Missing or invalid record_id returns an error — must match {sku}_{vintage} format from the catalogue
- Record ID not found in catalogue returns 404 or equivalent not-found error
- Payment not processed (x402 protocol failure) results in no record being returned
- Malformed record_id (wrong delimiter or format) will be rejected
- Network or upstream availability issues may cause timeouts

## How this service works

You get a checked official record: the official source hash and a Bitcoin stamp. That is Official checked records. Compare a model, a tweet, a FRED series, or the wrong table to this hash. If they differ, that copy is dirty. It is $0.25 per record_id. Not a stamp on a free PDF. Agent Trust Score comes from graded Proof of Outcome claims.

## Output

Returns a verified official record containing the canonical source hash and a Bitcoin timestamp (stamp), which can be compared against any copy of the data to detect tampering. Also surfaces an Agent Trust Score derived from graded Proof of Outcome claims.
