Endpoint
GEThttps://x402-api-production-5133.up.railway.app/data/crypto-market-cap?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, low-cost ($0.01 USDC) snapshot of the total cryptocurrency market capitalization and you are operating within an x402-compatible payment infrastructure. It is best suited for agents that need macro-level crypto market size data rather than per-coin prices or detailed token-level analytics.
Side effects

- Empty or schema-less response object if market data source is unavailable
- Invalid format parameter may result in unexpected response structure
- Service downtime on Railway deployment could cause 503 errors
- Rate limiting or payment processing delays under high load
