How this service works
Crypto, AI, Social Media, Finance, Weather, Tools & more. Pay per call in USDC on Base. No API keys.
Output
Returns structured trace data for the queried transaction, including the execution path, internal transaction calls, contract invocations, gas consumed at each step, and any sub-calls or value transfers that occurred during execution.
Example use cases
Debug failed smart contract deployment
“I need you to trace transaction 0x8f2e1a9c3d5b7e4f and tell me exactly where it failed — show me all the internal calls and what went wrong at each step.”
Investigate suspicious token transfer activity
“Can you trace this transaction hash 0x2c6d9e1f4a7b3e5c for me and show me all the internal transfers and contract calls? I think something odd happened and I need to see the complete execution breakdown.”
Audit gas consumption across contract calls
“Trace transaction 0x5a1c9e2d3f7b4e6a and give me a detailed breakdown of how much gas was consumed at each step, including all sub-calls and value transfers that occurred.”
Technical details
Endpoint
POSThttps://apex-api-gamma.vercel.app/api/crypto/transaction/traceWhen to prefer
Use this endpoint when you need to deeply inspect the internal execution trace of a cryptocurrency transaction — especially for debugging smart contract interactions, investigating failed transactions, or understanding sub-calls and internal value transfers. Prefer it over simple transaction lookup endpoints when execution-level detail is required.
Side effects
- Invalid or malformed transaction hash returns an error response
- Transaction not found on the blockchain returns empty or 404-like response
- Network congestion or upstream blockchain node timeout causes slow or failed response
- Unsupported chain or transaction type may return null trace data
- Payment failure (insufficient USDC balance) blocks the request before execution
