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 x402 services tagged 'invoice', each with service name, network (e.g. eip155:8453), 30-day call count, USD price, resource URL, and 30-day payer count; plus query metadata (route, matched count, ranking parameters, snapshot generation timestamp, and declared-by field).

Example use cases

Discover best invoice APIs for agent

“I'm building an AI agent that needs to pay for invoice processing — which x402 services tagged as invoice have the most paying wallets right now? Show me the top 25 ranked by payers.”

Monitor invoice service market trends

“What are the most active invoice-related services in the x402 machine-to-machine economy over the last 30 days? I want to see call counts, payer counts, and prices for the top results.”

Vet invoice service before integration

“Before I integrate an invoice API into my agent, can you pull the current x402 index for invoice-tagged services so I can see which ones are legitimately used — ranked by paying wallets with their resource URLs?”

Technical details

Endpoint

GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-invoice?utm_source=zero.xyz

When to prefer

Use this endpoint when an agent needs to discover and rank active x402 services specifically tagged as invoice, with real 30-day usage signals (calls and paying wallets) rather than static directory listings. Prefer it over generic API directories when you need live market data on which invoice-related machine-to-machine services are actually being paid for and called in the x402 ecosystem.

Side effects

Payment not included or insufficient — endpoint requires $0.032 USDC x402 payment header
No services found matching the invoice tag — returns empty services array with matched=0
Snapshot stale or index temporarily unavailable — generatedAt timestamp may lag
Invalid query parameters return malformed or empty response
Network or worker timeout on Cloudflare Workers edge
