## 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-deep-e67e5a85
```

Example prompt: Show me the top onchain x402 services ranked by paying wallets over the last 30 days — I want to see real call volume and price data with the snapshot hash.

## When to prefer this

Choose this endpoint when you specifically need ranked discovery of x402 services in the onchain/blockchain category, backed by real 30-day payment activity rather than self-reported metadata. It is ideal for agents that need to evaluate or compare live x402 APIs by actual usage, not just existence. Prefer it over generic x402 discovery endpoints when you want a leaderboard sorted by paying wallets in the onchain segment specifically.

## Known failure modes

- No services match the onchain tag filter — returns empty services array with count 0
- Snapshot data stale or unavailable — may return partial results or error
- Payment not processed (402) — caller must supply valid USDC payment header
- Rate limit exceeded — returns 429 with retry guidance
- Invalid or missing query parameters — returns 400 with schema validation error

## How this service works

Use when an agent needs the top x402 services tagged 'onchain-deep'. Returns Deep view: top 100 x402 services tagged 'onchain': ranked by 30-day unique paying wallets, with calls, price, network and calls-per-payer for each. 170 providers and 245 paying wallets measured in this tag.

## Output

A JSON object containing: total matched service count, the query parameters used (operator, limit, tag), the specific route (/in-onchain-deep), a list of ranked services each with name, network (e.g. eip155:8453), 30-day call count, price in USD, resource URL, and 30-day payer count, plus metadata including snapshot generation timestamp and declared-by field.
