  title: Seismic SRC20 Factory REST Tokens API
  version: '1.0'
  description: A read-only REST API that queries public metadata for SRC20 tokens deployed through the Seismic SRC20 Factory. It uses a standard public provider and holds no private key, so it can only read public on-chain state (name, symbol, decimals, owner, total supply) — never shielded balances or allowances. Addresses are returned as lowercase hex (not EIP-55 checksummed).

  note: Faithfully generated from Seismic's published SRC20 Factory REST API reference. Request/response shapes, the error envelope, and the documented base URL (a local factory service on localhost:3001) are transcribed verbatim from the docs; nothing was invented. This read-only REST surface queries SRC20 tokens deployed through the factory; it cannot read shielded state.
