Added

  • GET /api/v1/decode/{txHash}: decode any Base mainnet transaction into a human-readable action and normalized asset movements, priced at $0.005 in USDC via x402.
  • Logs-only decode engine covering ERC-20/721/1155 transfers, WETH, Uniswap v2/v3/v4 and Aerodrome swaps, approvals, and x402/EIP-3009 settlements.
  • Per-movement and gas USD valuation with null-severe pricing semantics.
  • Interactive playground that runs the full x402 pay-per-call flow on Base Sepolia.
  • Machine-readable surface: OpenAPI 3.1, /llms.txt, /llms-full.txt and a /.well-known/x402 manifest.

First public release. txdecode turns any Base transaction hash into a human-readable action plus normalized asset movements, paid per call in USDC over x402 — no account, no API key.
