# x402 Bazaar Rank — Token-Tagged Services

> x402 Bazaar Rank — Token-Tagged Services is a paid API for AI agents from x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-18).

Returns a ranked list of x402 services tagged 'token', 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-token-tagged-services-e65cb802
```

Example prompt: Show me the top 25 token-tagged x402 services ranked by number of paying wallets over the last 30 days, including their call counts and prices.

## When to prefer this

Use this endpoint when you specifically need to discover and rank x402-protocol services that carry the 'token' tag, scored by verifiable on-chain activity (calls and paying wallets) over the trailing 30 days. Prefer this over generic API directories when you need proof-of-usage metrics and a tamper-evident snapshot receipt. Not suitable for discovering non-token-tagged services or for general web API search outside the x402 ecosystem.

## Known failure modes

- No services indexed under the token tag — returns empty services array with matched:0
- Snapshot index temporarily unavailable — may return stale data or 503
- Rate limit exceeded at $0.001/call pricing tier — 402 payment required
- Malformed request parameters — may return 400 with error description
- Worker cold-start latency on first request — slightly elevated response time

## How this service works

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.

## Output

A JSON object containing: total matched services count, query metadata (ranking dimension, limit, tag filter, route), and an array of ranked services each with name, network identifier, 30-day call count, price in USD, resource URL, and 30-day unique payer count. Also includes a 'declaredBy' field, generation timestamp, and a snapshot hash for receipt/audit purposes.
