How this service works
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.
Output
A JSON object containing a list of up to 25 (configurable) x402 services tagged 'momentum', each with name, EVM network, 30-day call count, price in USD, resource URL, and 30-day unique payer count. Also includes query metadata (operator, limit, tag), total matched count, a snapshot hash for verifiability, scoring revision, declared-by field, and a generatedAt ISO timestamp.
Example use cases
Discover trending x402 APIs for integration
“I'm building an agent and want to know which x402 services tagged momentum have the most real traction — show me the top services ranked by paying wallets in the last 30 days so I can decide what to integrate.”
Monitor x402 market momentum weekly
“Pull the current momentum leaderboard for x402 services ranked by 30-day unique payers and save the snapshot hash so I can compare it against next week's rankings and track which APIs are rising.”
Due diligence on x402 service popularity
“Before I subscribe to this x402 API, can you check how it ranks in the momentum category — I want to see its 30-day call count, number of paying wallets, and price compared to the other top services on the list?”
Technical details
Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-momentum?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a real-usage-backed ranked view of x402 services specifically filtered to the 'momentum' tag — i.e. services that are actively gaining traction measured by paying wallets, not just declared availability. Prefer this over generic x402 directory endpoints when you want verifiable, snapshot-anchored rankings rather than static listings, and when 30-day payer count is the primary signal you trust for service quality.
Side effects
- No services match the momentum tag — returns empty services array with count 0
- Snapshot index temporarily stale — generatedAt timestamp may lag real-time by up to minutes
- Network error from Cloudflare Worker — HTTP 500 or 503 with no body
- Payment not processed — HTTP 402 returned if x402 payment header is missing or invalid
- Rate limiting — HTTP 429 if too many calls from same wallet in a short window
