Endpoint
GEThttps://api.x402node.dev/market/stablecoin-overviewWhen to prefer
Use this endpoint when you need a holistic, real-time view of the entire stablecoin market — total supply, rankings, and risk composition — rather than data on a single stablecoin token or price. Ideal for systemic risk assessment, market structure research, or DeFi macro analysis where LLM training data is too stale.

- Payment not included or insufficient — 402 Payment Required response
- Upstream data provider unavailable — 503 or 500 error with no market data returned
- Rate limit exceeded — 429 Too Many Requests
- Malformed request path — 404 Not Found
