## 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 x402-apis-username-osint-lookup-ea3e4674
```

Example prompt: Can you run an OSINT investigation on the username 'shadowpeak99' and tell me what public accounts and information are linked to it?

## When to prefer this

Use this endpoint when you need no-account, no-API-key OSINT investigation of a username and are able to pay per-request in USDC via the x402 protocol. Ideal for agents that need ad-hoc identity research without managing credentials or subscriptions. Prefer this over traditional OSINT tools when low-friction micropayment access is preferred and the query is sporadic rather than high-volume.

## Known failure modes

- Username not found on any platforms — returns empty or minimal results
- Payment not processed via x402 protocol — returns HTTP 402 Payment Required
- Invalid or missing username parameter — returns 400 Bad Request
- Username string too short or malformed — validation error
- Rate limiting or upstream OSINT source unavailability — partial or degraded results
- Service downtime — 500 Internal Server Error
