# x402 Bazaar Rank – /in-trust

> x402 Bazaar Rank – /in-trust is a paid API for AI agents from x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev, paid per call via x402, $0.032/call, status unknown (last checked 2026-10-19).

Returns a ranked list of x402 services filtered by the 'trust' tag, scored by real 30-day call volume and unique paying-wallet counts, with a snapshot hash and scoring-revision receipt.

## 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-trust-45f7cecf
```

Example prompt: Show me the top 25 trust-tagged x402 services ranked by paying wallets over the last 30 days, with their call counts, prices, and the snapshot receipt so I can verify the scoring revision.

## When to prefer this

Choose this endpoint when you need evidence-based discovery of x402 services — specifically those tagged 'trust' — ranked by actual 30-day usage and paying-wallet activity rather than self-reported metadata. It is ideal for agents vetting x402 APIs before integration, researchers analyzing the x402 ecosystem, or any workflow that needs a verifiable, receipt-backed snapshot of the live service market. Prefer alternatives if you need services from a different tag category or need real-time per-call telemetry rather than 30-day aggregates.

## Known failure modes

- No services match the trust tag — returns empty services array with matched:0
- Snapshot index is stale or unavailable — may return outdated generatedAt timestamp
- Rate limiting or payment failure (402) — request rejected if USDC payment header is missing or invalid
- Worker cold-start latency spikes on first request
- Malformed query parameters result in default fallback behavior rather than explicit error

## 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 the total matched service count, the query parameters used (ranking operator, limit, tag filter), the route, a list of up to N services each with name, network chain ID, 30-day call count, USD price, resource URL, and unique payer count over 30 days, plus metadata fields for who declared the snapshot, the snapshot hash, and the ISO timestamp of generation.
