Amounts ending in _raw, and amount_in / total_out / min_total_out and similar, are in the token's base units: divide by 10^decimals (precision differs per token; never assume one).\n- Token ids are KleverChain asset ids: KLV, KFI, and TICKER-XXXX for everything else (USDT-23V8, USDC-1LN4).\n- Fields are only ever added. Ignore fields you do not know; unknown values are null.\n- Rate limits, per IP: 120 requests a minute for data, 60 a minute for /api/route. Past that the answer is 429 with Retry-After (and retry_after_s in the body).\n- Signing, broadcasting and on-chain reads go through your own KleverChain node or Klever's public endpoints, not this API.\n- Endpoints not in this document are internal to the Swopus app and change without notice.",
