How this service works
444 endpoints across 9+ chains. Crypto, AI, Social, Finance, Weather, Tools. Pay per call in USDC via x402 with 4 facilitators: Dexter, Meridian, FluxA, GoPlausible.
Output
Returns a structured trace of the blockchain transaction including the full execution path, internal call stack, contract-to-contract interactions, sub-calls, value transfers, and any revert reasons for failed operations.
Example use cases
Debug failed DeFi transaction
“This transaction 0xabc123... failed on Ethereum — can you trace it and tell me exactly where in the contract call chain it reverted?”
Audit internal token transfers
“Trace transaction 0xdef456... for me and list all the internal token transfers and contract interactions that happened inside it.”
Investigate suspicious on-chain activity
“I want to understand what this transaction 0x789xyz... actually did on-chain — can you trace its full call stack and show me every contract it touched?”
Technical details
Endpoint
POSThttps://omni-api-cyan.vercel.app/api/crypto/transaction/traceWhen to prefer
Use this endpoint when you need deep visibility into a blockchain transaction beyond simple receipt data — particularly for debugging failed smart contract calls, auditing DeFi interactions, or forensically analyzing suspicious transactions across supported chains. Prefer this over simple transaction lookup endpoints when internal calls and sub-contract interactions matter.
Side effects
- Transaction hash not found on the specified chain — returns 404 or empty result
- Invalid or malformed transaction hash format — validation error
- Transaction too complex or trace data unavailable for the queried chain
- Rate limit exceeded or payment insufficient for the call
- Chain not supported by the endpoint — returns error indicating unsupported network
