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: count of returned results, the query parameters used (tag, ranking field, limit), the route, total matched services, and an array of ranked services each with name, network (EIP-155 chain ID), calls30d, priceUsd, resource URL, and payers30d. Also includes a declaredBy field and a generatedAt ISO timestamp identifying the snapshot.
Example use cases
Sourcing reliable emergency APIs for an agent
“I'm building an agent that needs to call emergency data services — can you pull the top emergency-tagged APIs from the x402 bazaar index, ranked by how many unique wallets paid for them in the last 30 days?”
Vetting emergency service demand before listing
“Before I launch my emergency alert API on x402, can you check what the current top emergency-tagged services look like in terms of call volume and payer counts so I can benchmark my pricing?”
Monitoring the emergency segment of the agent economy
“Give me a snapshot of the emergency slice of the x402 agent economy right now — which services are ranked highest by payers, and how does the matched service count look?”

Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-emergency?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a pre-filtered, ranked view of x402 services specifically tagged 'emergency' — it saves building a custom filter on the broader market index. Prefer it over the general market index when your agent only cares about emergency-use-case APIs and wants payer-ranked discovery with real 30-day usage data baked in. Not suitable if you need L402 services, per-service MPP listings, or cross-protocol totals.
Side effects
- No services tagged 'emergency' exist in the index — returns empty services array with matched:0
- Snapshot data is stale if the indexer hasn't run recently — generatedAt timestamp will reflect the lag
- Malformed response if the upstream bazaar index worker is unavailable (Cloudflare 503)
- Payment required error (HTTP 402) if the $0.04 USDC payment is not included in the request
- Tag filter returns fewer results than limit if fewer than 25 emergency services are indexed
