## 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 sherlockdata-username-osint-scanner-3f5d9ea3 -d '<json body>'
```

Example prompt: Run a full username footprint scan for 'john_doe_1987' — I want to see every website and platform where that handle is registered.

## When to prefer this

Use this endpoint when you need a comprehensive, multi-tool username sweep across 250+ sites in a single call, combining the coverage of Maigret, Sherlock, and WhatsMyName simultaneously. Prefer this over running individual OSINT tools manually when breadth of coverage matters and a small per-scan cost ($0.10 USDC) is acceptable.

## Known failure modes

- Username not provided or empty string returns 400 error
- Username exceeds 64 characters returns validation error
- Payment of $0.10 USDC not settled on Base mainnet causes request rejection
- Scan timeout if downstream OSINT tools are slow or rate-limited
- No matches found returns empty results list
- Invalid payment transaction returns authorization failure

## How this service works

Username goes in. Footprint comes out. Pay $0.10. 250+ sites scanned via Maigret + Sherlock + WhatsMyName, settled in USDC on Base via x402 protocol.

## Output

A report listing all matched sites and profile URLs where the given username was found across 250+ platforms, aggregated from Maigret, Sherlock, and WhatsMyName scans.
