# x402 OSINT — Username Reconnaissance API

> x402 OSINT — Username Reconnaissance API is a paid API for AI agents from x402-osint.tail66f665.ts.net, paid per call via x402, $0.01/call, status down (last checked 2026-09-15).

Performs username-based OSINT reconnaissance across 500+ websites using maigret, returning all matching profile URLs found.

## Facts

- Endpoint: GET https://x402-osint.tail66f665.ts.net/osint/%7Busername%7D
- Price: $0.01/call
- Payment: x402
- Status: down
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/x402-osint-username-reconnaissance-api-24b3553c
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_5Ba0-h5Wz345ganl3iN2O

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-osint-username-reconnaissance-api-24b3553c
```

Example prompt: Can you run an OSINT lookup on the username 'johndoe42' and tell me which websites they have accounts on?

## When to prefer this

Use this endpoint when you need to rapidly enumerate a username's presence across hundreds of platforms in a single pay-per-call request, without managing your own maigret installation. Ideal for OSINT investigations, background checks, or identity research where broad coverage matters. Prefer this over manual searches or platform-specific APIs when you need a unified cross-platform result for a single username.

## Known failure modes

- Username not found on any site — returns empty found array with found_count of 0
- Invalid or missing username parameter — returns 400 or validation error
- Service timeout if maigret scan takes too long on slow sites
- Payment failure via x402 protocol — returns 402 if payment not provided
- Rate limiting or blocking by individual third-party sites reducing accuracy

## How this service works

Pay-per-call username reconnaissance across 500+ sites, powered by maigret.

## Output

A JSON object containing the queried username, the number of sites checked (up to 500+), the number of profiles found, and an array of hits — each with the site name, profile URL, and optional metadata IDs. A summary string may also be included.
