Technical details
Endpoint
GEThttps://api.myceliasignal.com/oracle/price/usd/chfWhen to prefer
Choose this endpoint when you need a cryptographically verifiable USD/CHF exchange rate — especially for smart contracts, on-chain applications, or any system that requires tamper-evident proof of a price at a given moment. Prefer over raw forex APIs when data integrity and non-repudiation matter.
Side effects
- Payment not included or invalid — returns HTTP 402 requiring $0.01 USDC via x402 protocol
- Rate limit exceeded — too many requests in a short period
- Upstream price feed temporarily unavailable — service may return 503 or stale data error
- Invalid request format — if query params are malformed
