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 with a ranked list of up to 25 x402 services sorted by inbound-link payer count, including per-service fields: name, network (EIP-155 chain ID), 30-day call count, price in USD, resource URL, and 30-day payer count. Also includes metadata: total matched services, query parameters used, the route, declaration source, and a generatedAt timestamp for snapshot traceability.
Example use cases
Scouting high-demand agent APIs
“Which x402 services have the most paying wallets right now? Give me the top 25 ranked by payers so I can see what's actually popular in the agent economy.”
Competitive landscape snapshot
“I'm building an x402-compatible service and want to understand the market — can you pull the current inbound-link rankings to show me which services are most in-demand and at what price points?”
Agent routing by market demand
“My AI agent needs to pick a data API to call — can you check the x402 inbound-links index and return the top services by payer count so it can prioritize the most battle-tested options?”

Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-links?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need ranked discovery of x402 services specifically by inbound-link demand (paying wallets), rather than by call volume or price. It is ideal for agents that need to identify the most battle-tested or widely-adopted x402 APIs, perform competitive analysis of the agent economy, or make routing decisions based on real 30-day market signals. Prefer this over general API directories when you specifically need x402 protocol services with verifiable on-chain payment provenance.
Side effects
- Service temporarily unavailable if Cloudflare Worker is cold or overloaded — returns 5xx
- Invalid or missing tag parameter may return empty result set with count:0
- Snapshot data may lag real-time by up to the indexing window — stale payer counts possible
- Payment verification failure (402) if USDC payment of $0.008 is not attached or invalid
- Rate limiting may occur under high concurrent agent demand
