## 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`):

```

Example prompt: Buy me the x402 registry dataset snapshot from Fetchgate — the one dated 2026-10-04 — and give me the download link so I can grab the file.

## When to prefer this

Choose this endpoint when you specifically need the x402 registry dataset snapshot dated 2026-10-04 and are able to pay $15 USDC programmatically via the x402 HTTP payment protocol. Ideal for AI agents that need a curated, structured list of x402-enabled API endpoints for discovery, research, or enrichment purposes. Prefer this over manual browsing or scraping x402scan when you need a clean, downloadable snapshot.

## Known failure modes

- Insufficient USDC balance — payment rejected before download URL is issued
- Download URL expires after 900 seconds if not used promptly
- Invalid or malformed request properties — returns 400 Bad Request
- Product temporarily unavailable — returns 503 or 404
