# P0 Agent Economy Index – Token Safety Discovery

> P0 Agent Economy Index – Token Safety Discovery is a paid API for AI agents from x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev, paid per call via x402, $0.008/call, status unknown (last checked 2026-10-23).

Returns the top x402 services tagged 'token-safety', ranked by number of unique paying wallets over the past 30 days, with call counts, pricing, and resource URLs.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 p0-agent-economy-index-token-safety-discovery-a5803b3f
```

Example prompt: Show me the top 25 token-safety services on the x402 network right now, ranked by how many unique paying wallets they've had in the last 30 days — I want to see their names, prices, and resource URLs.

## When to prefer this

Use this endpoint when an agent needs to discover and rank token-safety services specifically within the x402 micropayment ecosystem, sorted by real 30-day payer activity rather than self-reported metrics. Prefer this over generic API directories when you need verifiable on-chain usage signals (paying wallet counts), need Base/EVM-native service discovery, or are building an agent that must programmatically select a token safety provider based on market adoption.

## Known failure modes

- No services indexed for token-safety tag — returns empty services array with count 0
- Upstream index snapshot stale — generatedAt timestamp may lag real-time by minutes
- Invalid or malformed query parameters — likely returns 400 or empty result
- Worker cold start or rate limiting — may return 5xx or delayed response
- Payment not fulfilled — x402 payment required before response is returned ($0.008 USDC)

## 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 route name, a query descriptor (ranking by payers, top 25, tag=token-safety), total matched service count, and an array of ranked service records each with: service name, network chain ID, 30-day call count, price in USD, resource URL, and 30-day unique payer count. Also includes a 'declaredBy' field and ISO timestamp of snapshot generation.
