Fees & limits

Rates are set by your agreement with us. The API returns yours; nothing on this site states a price.

Your fee schedule

GET /v1/fees

{"fees": [{"product": "SWAP", "currency": null, "rail": null,
           "percent": "...", "minimum_fee": "...",
           "priority": 0, "effective_from": "2026-09-01T00:00:00Z"}]}

Field
`product`	`SWAP`, `CRYPTO_WITHDRAWAL`, ...
`currency`, `rail`	`null` means any
`percent`	A percentage. `2` means 2%, not 0.02
`minimum_fee`	A floor in `currency`. A small amount pays this instead of the percentage
`priority`	Rows are ordered the way they are applied: most specific first, then by priority. The first row matching an operation prices it

Indicative. For a conversion, POST /v1/quotes is the price you are charged: it can also pick up a provider floor above the percentage. If you add your own margin, ours applies to what is left after yours: 3% then 2% is 4.94% of the original, not 5%.

Estimates

Two read-only calls price a payout or a withdrawal before you send it. An estimate reserves nothing and writes nothing. Values we cannot know are null, with the reason in usd_unavailable; they are never 0.

Chain payout

GET /v1/chain-payouts/estimate?network=tron&currency=USDT_TRC20&amount=500&address=T...

Scope chain_payouts:read. network is one of tron, bsc, ethereum, base, bitcoin, stellar; address, the destination, is optional.

{
  "network": "tron",
  "currency": "USDT_TRC20",
  "amount": {"amount": "500", "currency": "USDT_TRC20"},
  "fee": {"amount": "0", "currency": "USDT_TRC20"},
  "fee_usd": "0",
  "network_fee": {"amount": "...", "currency": "TRX"},
  "network_fee_usd": "...",
  "network_fee_charged_to_you": false,
  "recipient_holds_asset": true,
  "assumed_worst_case": false,
  "total_usd": "...",
  "usd_unavailable": [],
  "payouts_enabled": true,
  "limits": {
    "per_payout_usd": "...",
    "daily_usd": "...",

    "review_at_or_above_usd": "..."
  },
  "estimated_at": "2026-10-03T10:00:00Z"
}

Field
`amount`	What you asked to send
`fee`, `fee_usd`	Our fee. For chain payouts it is currently `0`
`network_fee`, `network_fee_usd`	The estimated network cost, in the network's own coin: TRX, BNB, ETH, BTC or XLM. `network_fee` is `null` when the network cost could not be read, with the reason in `usd_unavailable`; never `0`
`network_fee_charged_to_you`	Whether that network cost is charged to you today
`recipient_holds_asset`	TRON and EVM tokens: whether the destination already holds this token, which changes the energy or gas a transfer needs. `null` when no `address` was given or the read failed; the estimate then takes the worst case and `assumed_worst_case` is `true`
`total_usd`	The total in US dollars, or `null` when a part of it cannot be priced
`usd_unavailable`	Why a dollar figure is `null`, one string per reason
`payouts_enabled`	Whether payouts on this network are switched on for you
`limits`	Your payout policy and today's use of it. `null` where a limit is not set
`estimated_at`	When the estimate was made

Withdrawal

GET /v1/withdrawals/estimate?currency=USDT_TRC20&amount=100

Scope withdrawals:read.

Field
`amount`	What you asked to withdraw
`fee`, `fee_usd`	Our fee, from your `CRYPTO_WITHDRAWAL` rule
`network_fee`, `network_fee_usd`	The expected network cost. `null` when we have no figure for this currency, never `0`
`amount_received`	`amount − fee − network_fee`: what arrives. `null` while `network_fee` is unknown
`usd_unavailable`	Why a dollar figure is `null`
`estimated_at`	When the estimate was made

Refusals

Code	HTTP
`validation_failed`	422	Unknown network or currency, or an invalid amount. `detail` names the field
`forbidden_scope`	403	The key lacks the read scope

Limits

GET /v1/limits

The numbers applied to your key, not the service defaults:

Field
`requests.reads_per_minute`, `requests.writes_per_minute`	After any ceiling of your tenant
`requests.tenant_ceiling_per_minute`	Your own cap, or `null`. It can only tighten the two above
`requests.window_seconds`	The sliding window
`requests.idempotency_key_max_length`	120
`requests.quote_lifetime_seconds`	How long a quote lives
`money.withdrawal_limit_usd`, `money.withdrawal_spent_usd`, `money.withdrawal_remaining_usd`	Your rolling withdrawal limit. `remaining_usd` already counts what is in flight
`money.withdrawal_window_hours`	Rolling, not a calendar day

Chain payout limits are separate from the withdrawal limit and are returned by the payout estimate above.
