## 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-bazaar-rank-onchain-services-4715fd42
```

Example prompt: Show me the top 25 onchain-tagged x402 services ranked by number of paying wallets over the last 30 days, with their call volumes and prices.

## When to prefer this

Use this endpoint when you need an objective, usage-signal-backed ranking of x402 onchain services — specifically when you want to filter by the 'onchain' tag and rank by real payer or call activity rather than self-reported metadata. Prefer this over generic API directories when you need verifiable 30-day activity data with a cryptographic snapshot receipt for auditability. Best suited for agents doing marketplace research, integration vetting, or ecosystem monitoring in the x402 micropayment space.

## Known failure modes

- No onchain-tagged services indexed yet — returns empty list with count:0
- Snapshot unavailable or stale — may return outdated ranking data
- Payment of $0.008 USDC not completed — request rejected with 402
- Worker timeout or cold-start latency on Cloudflare edge — transient 5xx error
- Malformed query parameters — may return 400 or default fallback behavior

## How this service works

Use when an agent needs the top x402 services tagged 'onchain'. Returns Highest-demand x402 services tagged 'onchain': ranked by 30-day unique paying wallets, with calls, price, network and calls-per-payer for each. 165 providers and 235 paying wallets measured in this tag.

## Output

A JSON object containing a ranked array of up to 25 onchain-tagged x402 services, each with name, network (e.g. eip155:8453), 30-day call count, 30-day unique payer count, price in USD, and resource URL. Also includes query metadata (route, matched total, ranking operator), a snapshot hash for auditability, and a generatedAt timestamp indicating when the ranking was computed.
