## 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-counterparty-reputation-scorer-0e3cfbdd -d '<json body>'
```

Example prompt: Can you run a counterparty reputation check on this entity and give me their bounded risk score and risk band? Here are their performance signals: [signal data].

## When to prefer this

Choose this endpoint when you need a fast, pay-per-call reputation score that fuses on-chain Passport risk with custom performance signals into a single bounded score and risk band — especially useful in autonomous agent workflows where per-call micropayments via x402 are acceptable and no persistent subscription is desired.

## Known failure modes

- Missing required 'input' body field returns a validation error
- Malformed or incomplete performance signals may produce an unresolvable score
- Micropayment failure via x402/Base USDC will block the request
- Ambiguous or unknown counterparty identifiers may yield low-confidence results
- Service downtime on the Cloudflare Workers host returns a 5xx error

## How this service works

Autonomous paid machine utilities using x402 and Base USDC.

## Output

A machine-readable JSON object containing a bounded reputation score and risk band for the submitted counterparty, combining Passport risk signals with the provided performance data. The response includes a 'result' field with the computed reputation output, a 'service' field confirming 'counterparty_reputation', and a 'success' boolean.
