How this service works
ETH order book imbalance — depth and spread across 5 exchanges — Ed25519 signed attestation
Output
A signed payload containing ETH/USD order book depth metrics, bid-ask spread, and imbalance ratios aggregated across 5 exchanges, cryptographically signed with Ed25519 so the data can be verified for authenticity and tamper-resistance — suitable for use in smart contracts or trading systems requiring trusted off-chain data
Example use cases
Example prompt
“What's the current ETH/USD order book imbalance and spread aggregated across the 5 exchanges right now — and can you give me the signed attestation so I can verify it on-chain?”
Technical details
Endpoint
GEThttps://api.myceliasignal.com/oracle/orderbook/eth/usdWhen to prefer
Choose this endpoint when you need cryptographically verifiable ETH/USD order book data (depth, spread, imbalance) aggregated from multiple exchanges simultaneously — especially for DeFi smart contracts, on-chain protocols, or trading systems that need tamper-proof market microstructure signals rather than raw single-exchange data
Side effects
- Payment not received or invalid x402 payment header — 402 Payment Required
- Exchange data unavailable or stale — partial or degraded response
- Rate limit exceeded — 429 Too Many Requests
- Internal aggregation error across exchanges — 500 Internal Server Error
