revert.wtf AA-Decode is a paid API for AI agents from revert.wtf, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-11).
Decodes ERC-4337 UserOperation and EntryPoint revert bytes into human-readable error explanations for AAxx failure codes.
Paid hosted ERC-4337/UserOperation/EntryPoint failure decoder for AAxx messages or EntryPoint revert bytes.
A human-readable explanation of the ERC-4337 / EntryPoint revert, mapping AAxx error codes or raw hex revert bytes to a clear description of the failure reason, likely cause, and context within the UserOperation lifecycle.
POSThttps://revert.wtf/api/x402/aa-decode?utm_source=zero.xyzUse this endpoint specifically when debugging ERC-4337 account abstraction failures — AAxx error codes (AA10–AA50+), raw EntryPoint revert bytes, or UserOperation simulation rejections from a bundler. Prefer this over the generic revert.wtf decoder when you know the revert originates from ERC-4337 infrastructure (EntryPoint, paymaster, account contract). It provides targeted AA-domain context rather than generic EVM revert decoding.
