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 matched service count, the query parameters used, the route, and an array of up to 25 keyword-research-tagged x402 services each with name, network, 30-day call count, USD price, resource URL, and 30-day unique payer count, plus metadata on who declared the index, the snapshot hash, and when it was generated.

Example use cases

Discovering high-demand keyword research APIs

“Which keyword research services are agents actually paying for most in the x402 market? Give me the top ones ranked by unique paying wallets in the past 30 days, with their prices and call counts.”

Evaluating market viability before building a service

“Before I launch my keyword research API on x402, show me the competitive landscape — how many services are already tagged keyword-research, what do they charge, and which ones get the most real usage?”

Sourcing a keyword research tool for an agent pipeline

“I need to add a keyword research capability to my agent — find me the most-used keyword research services available on x402 right now, sorted by paying wallets, so I can pick one to integrate.”

When to prefer

Use this endpoint when an agent needs to discover real, actively-used keyword research APIs in the x402 ecosystem ranked by genuine economic activity (paying wallets and call volume), rather than relying on static directories or self-reported listings. It is ideal for agent pipelines that need to source or benchmark keyword research tools with verifiable 30-day transaction data.

Stale snapshot if the index has not been refreshed recently, indicated by an older generatedAt timestamp
