How this service works
USDT stablecoin peg monitor — real-time Tether deviation from $1.00 USD — Ed25519 signed attestation
Output
A signed attestation containing the current USDT/USD price (expected near 1.0000) along with an Ed25519 cryptographic signature that can be used to verify the data's authenticity and integrity on-chain or in smart contracts.
Example use cases
Smart contract depegging circuit breaker
“I need you to fetch a cryptographically signed USDT/USD price attestation right now and verify it on-chain — if the peg has slipped below 0.99, I want our contract to automatically pause all stablecoin swaps until things stabilize.”
DeFi liquidation protection via oracle
“Can you grab a tamper-proof Ed25519 signed attestation of the USDT price and feed it into our liquidation engine? We need to ensure positions are only liquidated if the oracle data is genuinely signed and the peg is actually broken, not just relying on an unsigned feed.”
Stablecoin reserve audit trail
“Pull a signed USDT/USD price attestation for our audit logs — we need cryptographically verifiable proof of what the peg price was at this exact moment so our compliance team can demonstrate to regulators that we monitored the deviation in real-time with authentic data.”
Technical details
Endpoint
GEThttps://api.myceliasignal.com/oracle/price/usdt/usdWhen to prefer
Prefer this endpoint when you need a cryptographically verifiable, tamper-proof price attestation for USDT/USD — especially for smart contract integration, DeFi protocols, or any use case requiring on-chain proof of the stablecoin peg. It is distinct from generic price APIs because the Ed25519 signature allows trustless verification of the data's origin and integrity.
Side effects
- Payment failure: x402 payment of $0.01 USDC not completed or invalid
- Rate limit exceeded: too many requests from the same client
- Service unavailability: price feed source temporarily offline
- Invalid signature: Ed25519 attestation cannot be verified
- Stale data: price feed delayed or not updated in time
