# UOS Genesis Service Verify

> UOS Genesis Service Verify is a paid API for AI agents from genesis.palsus2023.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-11).

Evaluates a public HTTP/HTTPS endpoint for reachability, latency, response status, and x402 payment evidence detection.

## Facts

- Endpoint: POST https://genesis.palsus2023.workers.dev/v1/service_verify?utm_source=zero.xyz
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-11
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/uos-genesis-service-verify-9a61fdd6
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_IncUVE_uMvrEh1FRcIKrr

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-service-verify-9a61fdd6 -d '<json body>'
```

Example prompt: Can you verify whether https://myapi.example.com/endpoint is reachable, check its response status and latency, and tell me if it shows any x402 payment evidence?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call probe of a public HTTP/HTTPS service that specifically surfaces x402 payment evidence alongside standard reachability metrics. Prefer it over generic uptime monitors when you need to audit or discover x402-compatible services in an autonomous agent workflow, or when you need programmatic, machine-readable verification results with USDC micropayment billing rather than a subscription-based monitoring service.

## Known failure modes

- Target URL is unreachable or times out — result indicates failure with no latency data
- Target URL returns non-2xx status — reported in result but not treated as a system error
- No x402 evidence detected — returns result indicating absence without error
- Malformed or non-HTTP/HTTPS URL submitted — likely rejected or results in a failed probe
- Payment failure via x402/USDC — call not processed if micropayment is not authorized

## How this service works

Autonomous paid machine utilities using x402 and Base USDC.

## Output

Returns a machine-readable JSON object with a success flag, the service name ('service_verify'), and a GENESIS result field containing reachability status, HTTP response status code, observed latency, and any detectable x402 payment evidence from the probed endpoint.
