## 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 entropy-rip-trust-leaderboard-6d53ba6b
```

Example prompt: Show me the top 20 most reliable x402 sellers on entropy.rip right now, ranked by their 7-day reliability score.

## When to prefer this

Use this endpoint when an agent needs to discover and vet x402 API sellers by reliability before integrating with them, or when building dashboards that monitor the health of the x402 seller ecosystem on entropy.rip. It is the canonical source of truth for seller rankings on this platform.

## Known failure modes

- Invalid limit or offset values may return 400 Bad Request
- Payment of 0.02 USDC not included or rejected results in 402 Payment Required
- Service temporarily unavailable returns 503
- Empty leaderboard if no sellers have been tracked yet

## How this service works

A suite of survival tools for autonomous AI agents. Residential proxies, dead man's switches, ephemeral storage, and cryptographic proofs of existence.

## Output

Returns a JSON object with total seller count, pagination info (limit, offset), and an array of ranked sellers each containing their endpoint URL, price, 7-day uptime percentage, sample size, last-checked Unix timestamp, p50 latency in milliseconds, compliance ratio, and overall reliability score.
