OpenAPI Specification

openapi: 3.2.0
info:
  description: This document covers Undertow feed routes, not every API on the shared api.seiche.info origin. Cross-market liquidity, exit-cost and attestation data. Free discovery and summaries; full-fidelity routes use x402. Research and market data, not investment advice.
