## 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-accessibility-services-de49aba2
```

Example prompt: Show me the top 25 accessibility-tagged services on the x402 bazaar, ranked by number of paying wallets over the last 30 days, and include the snapshot hash so I can verify the data.

## When to prefer this

Choose this endpoint when you specifically need ranked, usage-validated discovery of x402 services in the accessibility domain. It is ideal when you want to avoid guessing which services are active — real 30-day call and payer data de-risks selection. Prefer it over generic x402 directory listings when you need a trustworthy, scored snapshot with a verifiable receipt hash.

## Known failure modes

- No accessibility-tagged services indexed yet — returns empty services array with count 0
- Snapshot index temporarily stale — generatedAt timestamp may lag real-time by minutes
- Invalid or unrecognized tag filter — may return empty results or 400 error
- Payment of $0.032 USDC not fulfilled — 402 Payment Required response
- Worker cold-start latency spike on first call after idle period

## 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 accessibility-tagged x402 services, each with name, network chain ID, 30-day call count, price in USD, resource URL, and 30-day paying wallet count. Also includes query metadata (ranking op, limit, tag), total matched count, snapshot hash (declaredBy field), and a generatedAt ISO timestamp for auditability.
