How this service works
Demand analytics measured on the SYNTHORA x402 mesh (real Caddy access logs, weekly aggregate): which endpoints agents probe, how many hits end in 402 (unpaid interest), 200 conversions, unique IPs and published prices. Ed25519-signed. Pay-per-use via x402 USDC on Base.
Output
A signed JSON object containing a ranked list of x402 endpoints (up to 25), each with total hits, HTTP 200 paid conversions, HTTP 402 unpaid probes, unique IPs, and USDC price, plus aggregate stats: total requests across the mesh, number of active x402 endpoints, and the as-of timestamp. The response includes a 'vista' label indicating which filter was applied and a source attribution noting Caddy log aggregation.
Example use cases
Spot high-interest unpaid endpoints
“Show me up to 20 endpoints from Demand Radar where agents are hitting the wall with 402s but not converting — I want to see the sin_pagar view to find underpriced or high-demand APIs.”
Track which APIs are actually selling
“Give me the top 15 endpoints in the compradas view on Demand Radar so I can see which x402 services are getting real paid conversions this week.”
Identify dead endpoints with no traffic
“Use Demand Radar with the nadie_toca vista and return up to 25 results — I need to know which x402 endpoints have no agent traffic at all so I can clean up the mesh.”
Technical details
Endpoint
POSThttps://demand-radar.hergertsynthora.com/serviceWhen to prefer
Use this endpoint when you need real, measured demand signals from the SYNTHORA x402 mesh rather than self-reported or estimated usage — particularly when deciding which endpoints to build, price, or list. It is uniquely suited for agents that need to understand the economics of micropayment APIs: conversion rates, probe-to-purchase ratios, and price sensitivity across live endpoints. Prefer it over generic API analytics when your domain is specifically the x402/agent-economy ecosystem.
Side effects
- Invalid 'vista' enum value returns validation error
- 'limit' exceeding 25 rejected by schema
- Missing or invalid x402 payment header returns 402 before data is served
- Stale data if weekly aggregation has not yet completed for the current period
- Signature verification failure if Ed25519 key mismatch on client side
