Technical details
Endpoint
GEThttps://x402-market.kore-app.workers.dev/v1/market?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a single aggregated crypto market intelligence call covering prices, sentiment, DeFi TVL, and stablecoin yields together. Prefer it over fragmented calls to individual price APIs, DeFi dashboards, or yield aggregators when you want a unified snapshot paid as a cheap $0.01 USDC micropayment via x402.
Side effects
- Payment not provided or invalid x402 USDC payment on Base → 402 Payment Required
- Malformed input body → 400 Bad Request
- Worker or upstream data source unavailable → 503 or 500 error
- Stale data if upstream DeFi/price feeds are delayed → generatedAt timestamp may be old
