## 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-ofac-tagged-services-494ee4f5
```

Example prompt: Pull the top 25 x402 services tagged 'ofac' right now, ranked by the number of unique paying wallets over the last 30 days, and include the snapshot hash so I can verify the data provenance.

## When to prefer this

Use this endpoint when you specifically need to discover x402 micropayment services tagged for OFAC or sanctions compliance, ranked by real economic activity (paying wallets) rather than self-reported metadata. It is the right choice over generic x402 market indexes when the user's concern is OFAC-category services specifically, and over off-chain compliance databases when you need APIs that accept x402 payments and have verifiable 30-day usage receipts.

## Known failure modes

- No services indexed under the 'ofac' tag — returns empty array with count 0
- Snapshot index temporarily unavailable — may return stale or cached data
- Malformed query parameters — ignored silently or returns default result
- Rate limiting or payment failure — HTTP 402 or 429 response
- Worker cold start latency on first request 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 up to 25 x402 services tagged 'ofac', each with name, network chain ID, 30-day call count, price in USD, resource URL, and 30-day unique paying wallet count. Also includes total matched service count, the query parameters used, the route, a 'declaredBy' field, a generatedAt timestamp, and a snapshot hash plus scoring revision for auditability.
