## 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 quantaflow-rapid-skip-tracing-api-7cec539f -d '<json body>'
```

Example prompt: Use the rapid skip tracing service to find the current address and phone number for John Smith, last known to be in Austin, Texas.

## When to prefer this

Choose this endpoint when you need quick, pay-per-call skip tracing without a subscription, especially in a web3 or DeFi-native workflow where USDC micropayments via x402 are preferred over traditional API key billing. Suitable for low-volume, on-demand lookups where cost per call ($0.01 USDC) is acceptable.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 payment not accepted — returns 402 Payment Required
- No results found: person not found in skip trace database — upstream returns empty or null result
- Invalid input: malformed query body forwarded to upstream — upstream may return 400 error
- Upstream unavailability: the proxied skip tracing service is down — gateway may return 502 or 503
- Rate limiting: upstream skip tracing API throttles requests — returns upstream error code

## How this service works

Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.

## Output

Returns the upstream skip tracing service's raw response containing contact details such as current addresses, phone numbers, and other identifying information for the queried individual, passed through after successful $0.01 USDC payment via the x402 protocol.
