How this service works
Micropay research APIs (x402 v2 + bazaar). Free catalog at /.well-known/x402.json. Primary v2 accepts: Base eip155:8453 only. Legacy X-PAYMENT-TX still supports bsc|base via acceptsV1. Headers: X-PAYMENT-TX, X-PAYMENT-NETWORK, PAYMENT-SIGNATURE. No financial advice.
Output
Returns a JSON object with an 'ok' boolean, a 'pairs' array listing available pair entries, and a 'product' string set to 'pair_digest'. May return an empty pairs array if no matching pairs exist for the given filter.
Example use cases
Discover available trading pairs
“What pairs are listed in the DESK LEAD pair digest right now? I want to see which ones are currently available before I build my research pipeline.”
Filter pairs by property
“Can you fetch the DESK LEAD pair digest and filter it by the 'stablecoin' property so I only see stablecoin-related pairs?”
Audit x402 research catalog
“I'm auditing a micropay research setup — can you pull the pair digest from DESK LEAD and tell me how many pairs come back and what the product identifier says?”
Technical details
Endpoint
GEThttps://desk-x402.desk-x402-gh.workers.dev/v1/pair-digestWhen to prefer
Use this endpoint when you need a structured digest of available pairs from the DESK LEAD micropay research API and are prepared to pay $0.25 USDC per call via the x402 v2 protocol on Base. Prefer this over direct catalog browsing when you need machine-readable pair metadata in a single call rather than navigating the free /.well-known/x402.json catalog.
Side effects
- Payment not included or invalid: 402 response requiring X-PAYMENT-TX header with valid Base (eip155:8453) USDC payment
- Invalid network: endpoint rejects payment on unsupported chains (primary v2 requires Base only)
- Malformed properties filter: unexpected properties string may return empty pairs or error
- Worker downtime: Cloudflare Worker unavailability returns 5xx
- Signature mismatch: invalid PAYMENT-SIGNATURE header causes rejection
