How this service works
GlianaAI - Pay-per-call AI models, live market data, SEC filings and identity APIs, no signup, USDC. This resource: tools/calldata-decode. Work out what a transaction actually does, before signing it. https://ai.glianalabs.com
Output
A JSON response containing the decoded calldata broken into its component parts: the function selector, function name (if ABI is known), and the decoded typed parameters and their values, making the raw hex human-readable.
Example use cases
Inspect suspicious transaction input
“I have this raw transaction calldata from an Ethereum transaction I'm reviewing: 0x23b872dd000000000000000000000000abc...123 — can you decode it so I can see what function was called and what arguments were passed?”
DeFi swap call analysis
“Decode this calldata from a Uniswap interaction so I can confirm it's doing a token swap and not something else: 0x38ed1739000000000000000000000000000000000000000000000006f05b59d3b20000”
Smart contract debugging
“I'm debugging a failed transaction and need to understand what the contract was supposed to do — can you decode this calldata hex: 0x095ea7b3000000000000000000000000spender0000000000000000000000000000000000000000000000000de0b6b3a7640000”
Technical details
Endpoint
GEThttps://api.glianalabs.com/x402/tools/calldata-decode?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call (no subscription) calldata decoder that accepts raw EVM hex input and returns structured decoded output. Ideal for agents that only occasionally need to decode transactions and want to avoid maintaining their own ABI parsing infrastructure. Useful for cross-chain or multi-protocol scenarios given GlianaAI's broad blockchain data coverage.
Side effects
- Invalid or malformed hex calldata returns a decode error
- Unknown function selector with no matching ABI returns partial decode with only raw bytes
- Empty or missing input body results in a 400 bad request
- Payment not included or insufficient USDC results in 402 Payment Required
- Calldata for a non-standard or custom ABI may not fully decode without ABI context
