Public API v1

  • Public routes under /v1 with an OpenAPI 3.1 spec at GET /v1/openapi.json.
  • Trading after graduation goes straight to the coin's DAMM v2 pool. Jupiter only as a marked fallback.
  • Launch API: POST /v1/launches with custom (vanity) mints signed by the integrator.
  • Signed webhooks with retries, a WebSocket with channels, rate limits with RateLimit headers, self-serve keys by wallet signature.
  • Coins are "tokens" in public paths. The older site routes under /v1/coins stay as they are.
