## 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-in-liquidity-646f48f4
```

Example prompt: Show me the top 25 liquidity-tagged x402 services ranked by number of unique paying wallets in the last 30 days, and include the snapshot hash so I can verify the scoring revision.

## When to prefer this

Choose this endpoint when you need a ranked, real-traffic-backed view of x402 services specifically in the liquidity domain, where call volume and unique paying wallets over 30 days are the trust signals that matter. Prefer it over generic API directories or static registries when you want live usage data rather than self-declared metadata. It is particularly valuable when selecting or auditing x402 liquidity APIs before integration, since the scoring is based on actual on-chain payment activity rather than marketing copy.

## Known failure modes

- No services matched the liquidity tag — returns empty services array with count 0
- Payment of $0.008 USDC not provided or invalid — returns HTTP 402 with payment required details
- Snapshot index temporarily unavailable — may return stale or partial data
- Rate limiting or worker timeout on Cloudflare edge — returns 5xx error
- Malformed query parameters — returns 4xx with error description

## How this service works

An open index of the machine-to-machine (agent) economy. x402 routes: ranked discovery over the live x402 service market, every indexed service scored by real 30-day calls and paying-wallet bounds, with a receipt naming the snapshot hash and scoring revision. /economy routes, for Tempo MPP, Virtuals ACP, Olas, Masumi, ERC-8004 agent registries, Solana agent registries, Base agent contracts and MCP servers (Official MCP Registry): each protocol's published figures (agent or server counts, transactions or payment events; payers and USD volume only where the source publishes them: payers for x402 and Tempo MPP, USD volume for x402 and Virtuals ACP), each with its unit, window and source; units differ, so totals are not summed. L402 and per-service MPP listings are not covered.

## Output

A JSON object containing a ranked array of up to 25 x402 services tagged as liquidity, each with name, network chain ID, 30-day call count, price in USD, resource URL, and unique payer count over 30 days. Also includes the total matched service count, the query parameters used, the route, a declaredBy field, the generatedAt timestamp, and a receipt identifying the snapshot hash and scoring revision for auditability.
