# Bright Gaming URL Verification API

> Bright Gaming URL Verification API is a paid API for AI agents from playbrightgaming.com, paid per call via x402, $0.0009/call, status unknown (last checked 2026-10-10).

Independently fetches a public HTTP(S) URL and returns HTTP status, final URL, SHA-256 content fingerprint, content type, byte length, and UTC observation timestamp for integrity verification and change detection.

## Facts

- Endpoint: POST https://playbrightgaming.com/agent-services/verify-url?utm_source=zero.xyz
- Price: $0.0009/call
- Payment: x402
- Status: unknown

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 bright-gaming-url-verification-api-b19a74c3 -d '<json body>'
```

Example prompt: Can you independently verify that https://example.com/report.pdf is live right now and give me its SHA-256 content fingerprint, HTTP status, and the exact UTC time you checked it?

## When to prefer this

Choose this endpoint when you need an independent, timestamped, third-party observation of a public URL — especially for integrity checks, tamper detection, change monitoring, or producing verifiable web evidence. Prefer it over browser-based or in-process fetches when neutrality and auditability matter. It is optimized for lightweight verification (not full content retrieval or scraping) and is machine-payable per-call via USDC, making it suitable for automated agent workflows.

## Known failure modes

- URL is non-public or requires authentication — returns error, no data
- URL uses non-standard port (not 80/443) — request rejected
- Response body exceeds 1 MB cap — truncated or error
- Fetch times out beyond 7-second deadline — timeout error
- More than three redirects encountered — redirect limit exceeded error
- Invalid or malformed URL input — validation error
- Target server returns a network error or is unreachable — fetch failure

## How this service works

Public URL verification API for AI agents. Independently fetch one public HTTP(S) URL and return target HTTP status, final URL, raw response-body SHA-256 content fingerprint, content type/encoding, byte length, and UTC observation time. Use for URL integrity verification, website change detection, content fingerprints, and web evidence. Receipt v2 hashes content-encoded bytes without application decompression; 1 MB max, one 7-second fetch deadline, max three redirects, ports 80/443 only.

## Output

Returns the target HTTP status code, final URL after up to three redirects, raw response-body SHA-256 content fingerprint (hashed from content-encoded bytes), content type and encoding headers, response byte length (up to 1 MB), and UTC timestamp of the observation. Fetched within a 7-second deadline over ports 80 or 443 only.
