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 a ranked list of up to 25 agent-skill tagged x402 services, each with name, network identifier, 30-day call count, price in USD, resource URL, and 30-day unique paying wallet count; also includes total matched service count, query metadata, snapshot generation timestamp, and a receipt identifying the snapshot hash and scoring revision.
Example use cases
Discovering most-used agent capabilities
“What are the most economically active agent-skill services on the x402 network right now? I want to see the top 25 ranked by real paying wallets over the last 30 days, including their call counts and prices.”
Agent marketplace curation for a platform
“I'm building an agent marketplace and need to surface the highest-demand agent-skill APIs that other agents are actively paying for — pull the current top services from the x402 agent-skill index with their payer counts and pricing.”
Evaluating agent skill service landscape
“Before I build a new agent skill API, can you show me what's already popular in the x402 agent economy under the agent-skill tag, so I can see what's crowded and what real usage looks like across the top ranked services?”
Technical details
Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-agent-skill?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to discover which x402 services tagged 'agent-skill' are most economically active, validated by real 30-day paying-wallet data rather than self-reported metrics. Prefer this over generic API directories when you need usage-weighted ranking specific to the agent economy, or when you need a verifiable snapshot receipt for auditing which agent-skill services were ranked at a given point in time.
Side effects
- No services match the agent-skill tag — returns empty services array with matched:0
- Snapshot data may be stale if the indexer has not refreshed within the current window
- Network errors from Cloudflare Worker returning 5xx if upstream index is unavailable
- Malformed response if the scoring revision changes and schema shifts unexpectedly
