# Paylyte Proof of Outcome — BLS/Board Claim Grader with Bitcoin Timestamp

> Paylyte Proof of Outcome — BLS/Board Claim Grader with Bitcoin Timestamp is a paid API for AI agents from api.paylyte.ai, paid per call via x402, $9.99/call, status unknown (last checked 2026-10-11).

Grades a locked economic claim against an official BLS or Board statistical release, then returns a Bitcoin-timestamped Proof of Outcome record for that print.

## 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-proof-of-outcome-bls-board-claim-grader-with-bitcoin-timestamp-2c53779c
```

Example prompt: Can you pull the Paylyte Proof of Outcome for BLS print_id 'CPI-2024-10' and show me the grade, the official source hash, and the Bitcoin OpenTimestamps record?

## When to prefer this

Choose this endpoint when you need a cryptographically verifiable, Bitcoin-timestamped record proving how a locked economic claim graded against an official BLS or Federal Reserve Board statistical release. Prefer it over raw BLS data dumps when audit-trail integrity, tamper-proof provenance, or Agent Trust Score building is required. Not suitable for simply fetching raw economic data without a verification or grading use case.

## Known failure modes

- Missing or invalid print_id returns an error — print_id must be obtained first from GET /v1/prints/calendar
- print_id not yet available if the official release has not yet dropped
- Payment failure (x402) if USDC payment of $9.99 is not completed before data is returned
- CPI morning releases require two separate print_id purchases ($19.98 total) or second call returns incomplete data
- Bare GET without print_id returns only the payment template, not actual outcome data

## How this service works

Paylyte grades a locked claim against the official BLS or Board print, then stamps the record on Bitcoin. You buy Proof of Outcome: the hashed official payload, the grade, and the OpenTimestamps record. It is $9.99 per print_id. A Consumer Price Index morning is two buys ($19.98) if both print_ids are sold. Not a raw BLS dump. Not an official BLS or Board product. Agent Trust Score comes from graded claims.

## Output

Returns a Proof of Outcome object containing: the official source payload hash (from BLS or Board), the grade (correct/incorrect) for the locked claim, and the OpenTimestamps Bitcoin blockchain record. This constitutes cryptographic proof that the claim was evaluated against the official release at a specific point in time.
