GhostSwap

List all coins GhostSwap supports for swapping (1,600+ assets). Use lite=true for just an array of tickers (e.g. ["btc","eth","ltc"]).

Get the min and max swap amount for a single (from, to) pair. Returns separate min/max for float-rate and fixed-rate modes.

Check whether a wallet address is valid for a given currency. Returns {valid:true} or {valid:false,message}. Permissive pre-check — create_swap runs a stricter validator.

Get a live swap quote — rate, amountUserReceives, network fee, min/max. Always display amountUserReceives (not amountTo). mode="fixed" locks the rate and returns a short-lived rateId.

Create a new swap. Returns payinAddress where the end-user must send funds. REQUIRES refundAddress (the user's own wallet on the FROM chain). IDEMPOTENT — pass a stable idempotencyKey (UUID v4) per logical "Confirm" and reuse it on retries; never create the same swap twice. If a result has stop:true

Get the current status of a swap by id. Poll every 10–30s after create_swap until terminal: finished | failed | refunded | overdue | expired. `hold` = AML/KYC review (slow polling; direct end-user to support@ghostswap.io).
