Technical details
Endpoint
GEThttps://api.myceliasignal.com/oracle/price/brl/usd?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cryptographically verifiable, signed BRL/USD exchange rate derived from live crypto exchange order books rather than traditional forex APIs. Especially valuable when you need DePix peg pricing, an auditable Ed25519 attestation for compliance or logging, or 24/7 availability without traditional banking hours constraints.
Side effects
- Exchange order book data temporarily unavailable, causing rate computation failure
- Ed25519 signing service failure preventing attestation generation
- Rate limiting or payment verification failure for the $0.01 USDC per call fee
- Stale or missing USDT/BRL or USDT/USD order book data leading to no price output
