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 returned services (up to the limit), the query parameters used (ranking criterion, limit, tag filter), the route, the total number of matched services in the index, an array of ranked service objects (each with name, network, 30-day call count, USD price, resource URL, and 30-day payer count), who declared the data, and a generatedAt ISO timestamp anchoring the snapshot.
Example use cases
Audit DKIM-capable agent services
“Give me the top 25 DKIM-tagged x402 services sorted by paying wallets so I can see which ones have real economic activity in the last 30 days.”
Select a vetted email-auth API for my agent
“I want to pick a DKIM-supporting x402 service for my agent to use — show me the most-used ones ranked by payer count so I can trust they're legit.”
Monitor DKIM service market trends
“Pull the latest ranked snapshot of DKIM-tagged services in the x402 bazaar and tell me how many unique services matched and which have the highest 30-day call volumes.”
Technical details
Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-dkim?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need discovery of x402 services filtered to the 'dkim' tag and ranked by real economic signals (paying wallets, call counts) rather than self-reported metadata. Prefer this over generic API directories when you need cryptographic provenance (snapshot hash) of the ranking, or when your agent needs to select a DKIM-capable service based on actual 30-day market activity rather than vendor claims.
Side effects
- No DKIM-tagged services found — returns empty services array with matched:0
- Upstream index unavailable — HTTP 5xx with no body or timeout
- Malformed query parameters — may return all services ignoring filter
- Stale snapshot — generatedAt timestamp may lag real-time by up to the indexing window
- Payment not settled — HTTP 402 response requiring x402 micropayment before data is returned
