Foundry Base Transaction Explainer
x402
Foundry Base Transaction Explainer is a paid API for AI agents from minty-sprout.onrender.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-11-01).
Decodes a Base chain transaction hash into human-readable details: status, block, gas, ETH value, method selector, contract creation, and decoded ERC-20 token transfers.

How this service works
Base transaction explained from the chain: success or reverted, block and time, from, to, ETH value, method selector, gas used and fee, contract created, and every ERC-20 transfer decoded with token symbol and amount. Input: 0x transaction hash. Deterministic, no LLM.
Output
A JSON object containing: transaction found flag, success/reverted status, block number, from and to addresses, ETH value, method selector, gas used, fee in ETH, contract created address (if any), and an array of decoded ERC-20 token transfers each with from, to, token contract address, token symbol, and amount.
Example use cases
Verify DeFi token transfer completed
“I sent some USDC on Base a few minutes ago and I want to confirm it went through — can you look up transaction 0x920b38d85c8dccaa06e1dae783f057feebd571260aefb7f055a04c60b708df1f and tell me the status and how much USDC moved?”
Debug a reverted transaction
“My transaction on Base seems to have failed — can you decode 0x4a3f8c12e9b76d501f234a6789cde012345678901234567890abcdef12345678 and tell me if it reverted and what method it was trying to call?”
Audit on-chain activity for a tx
“I need a full breakdown of this Base chain transaction for my records — from and to addresses, ETH value, gas fees, block number, and any ERC-20 transfers: 0x1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6e7f8a9b0c1d2e3f4a5b6c7d8e9f0a1b2c”
Technical details
Endpoint
POSThttps://minty-sprout.onrender.com/v1/base-tx-explain?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need deterministic, no-hallucination decoding of a specific Base chain transaction by hash — especially when you need ERC-20 transfer details decoded with human-readable token symbols and amounts. Prefer this over general blockchain explorers when operating in an agent workflow that requires structured JSON output and pays per-call via x402.
Side effects
- Transaction hash not found on Base chain — returns found: false
- Invalid hash format (not 0x + 64 hex chars) — likely returns validation error
- Transaction is too recent and not yet indexed — may return not found
- Network or RPC timeout — service unavailable error
- Non-Base chain transaction hash provided — will not be found
