# UOS Genesis Attestation Receipt

> UOS Genesis Attestation Receipt is a paid API for AI agents from genesis.palsus2023.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Generates an attestation receipt for a UOS Genesis machine utility operation, providing cryptographic proof of execution

## Facts

- Endpoint: POST https://genesis.palsus2023.workers.dev/v1/attestation_receipt
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/uos-genesis-attestation-receipt-4ba3f55b
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_hKdf7twsB_AbPX2TC61B3

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 uos-genesis-attestation-receipt-4ba3f55b -d '<json body>'
```

Example prompt: Can you get an attestation receipt from the UOS Genesis machine for this input data: 'job-run-abc123'?

## When to prefer this

Choose this endpoint when you need a cryptographic attestation receipt specifically from the UOS Genesis machine utility — particularly for audit trails, proof-of-execution, or integrity verification of Genesis-processed operations. Not suited for general-purpose hashing, signing services, or attestation from other providers.

## Known failure modes

- Missing or empty input field returns a 400 error
- Invalid params structure may cause processing failure
- Payment of 0.005 USDC not supplied or rejected results in 402 Payment Required
- Server-side Genesis machine unavailability returns 503
- Malformed input data may produce an attestation error rather than a valid receipt

## How this service works

UOS Genesis machine utility: attestation_receipt

## Output

Returns an attestation receipt — a cryptographic or signed proof document confirming that the Genesis machine utility executed the provided input. Typically includes a receipt token, timestamp, and verification metadata.
