## 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

## When to prefer this

Use this endpoint when you need a quantified trust signal for a blockchain payee or service URL before transacting, integrating, or routing payments — especially in automated agent workflows where manual due diligence is impractical. Prefer this over generic blockchain explorers when you need a single scored output rather than raw transaction data.

## Known failure modes

- Invalid or unrecognized chain identifier returns an error
- Malformed payee address causes validation failure
- service_url not reachable or not recognized on-chain
- timeframe_days outside 1–365 range rejected
- Insufficient on-chain history for payee results in low-confidence or null score
- Payment failure via x402 protocol blocks the request

## How this service works

Heuristic authenticity signals based on public payment graph observations and caller-provided context.

## Output

A JSON response containing an authenticity score and supporting on-chain metrics reflecting the legitimacy of the specified payee and/or service URL over the requested timeframe on the given blockchain.
