How this service works
Decodes raw EVM transactions and calldata into agent-readable intent: function signature, decoded arguments, and ERC-20 transfers. POST /v1/evm with {tx_hash, chain_id} and get one JSON object back. Fully deterministic: input determines output. Pay per request in USDC; no account, no API key.
Output
A single JSON object containing the decoded function signature (name and parameter types), the decoded argument values mapped to their parameter names, and a list of any ERC-20 token transfer events detected within the transaction, making the on-chain intent fully human- and agent-readable.
Example use cases
Audit a suspicious DeFi transaction
“Someone sent me this transaction hash 0xabc123...def456 on Ethereum mainnet (chain ID 1) and I want to know exactly what contract function it called and what arguments were passed — can you decode it for me?”
Track ERC-20 transfers in a tx
“Decode this transaction 0xdeadbeef...cafe9876 on Polygon (chain ID 137) and tell me which ERC-20 tokens were transferred, from which address, to which address, and in what amounts.”
Verify a smart contract interaction
“Before I trust this transaction, can you decode 0x1234abcd...5678ef90 on Arbitrum (chain ID 42161) and confirm what function was called and what the decoded input arguments actually are?”
Technical details
Endpoint
POSThttps://agent.pocket.network/v1/tx-decoding?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to understand the semantic intent of an EVM transaction — what function was called and with what arguments — without setting up a full node or managing API keys. It is especially useful for DeFi monitoring, transaction auditing, wallet activity summarization, and compliance workflows. Prefer this over raw JSON-RPC eth_getTransaction calls when human-readable decoded output is needed immediately, and over block explorers when programmatic JSON output is required for downstream processing.
Side effects
- Transaction hash not found on the specified chain — returns error if the tx does not exist or hasn't been indexed yet
- Invalid or malformed tx_hash format — returns validation error for non-0x-prefixed or wrong-length hashes
- Unsupported chain_id — returns error if the requested EVM chain is not supported by Pocket Network
- Unverified contract ABI — function selector may be decoded with best-guess ABI if not publicly verified, resulting in partial or generic output
- Payment failure — request rejected if USDC payment via x402 protocol is not successfully attached
