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 count of matched results (up to 25), the query parameters used (ranking by payers, top 25, devtools tag), the matched total in the index, an array of services each with name, network (e.g. eip155:8453), 30-day call count, price in USD, resource URL, and 30-day unique payer count, plus metadata including who declared the data, the snapshot generation timestamp, and the scoring revision receipt.
Example use cases
Discover popular devtools APIs for an agent
“I'm building an AI agent that needs developer tools — can you pull the top devtools services from the x402 agent economy index, ranked by how many unique wallets paid for them in the last 30 days?”
Audit devtools market demand for product strategy
“I want to understand which developer tool APIs are getting the most traction in the machine-to-machine economy — fetch the ranked devtools list from the x402 index and show me call counts and payer numbers.”
Find affordable devtools services with real usage
“Can you look up the devtools-tagged services in the x402 agent economy index and filter for ones with real paying users? I want to see pricing alongside the 30-day activity so I can pick something cost-effective.”
Technical details
Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-devtools?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to discover real, actively-used developer tool APIs in the x402 agent economy, ranked by genuine economic signal (unique paying wallets) rather than self-reported popularity. It is the right choice over generic API directories when you need machine-to-machine market intelligence specifically for the devtools vertical, backed by a verifiable 30-day snapshot with a receipt hash. Do not use it for L402 listings, Tempo MPP per-service listings, or cross-protocol aggregated totals.
Side effects
- No services tagged 'devtools' currently indexed — returns empty services array
- Snapshot temporarily stale if the indexing worker has not run recently
- HTTP 402 if USDC payment of $0.048 is not attached or is insufficient
- Worker timeout if the index is large and filtering is slow
- Malformed response if the upstream registry sources are unavailable
