Swap real mainnet tokens for testnet funds in four API calls. Base URL https://drip.tools/api, JSON over HTTPS, no auth, open CORS. Pay from ten EVM mainnets, Solana or TON; receive on 30+ EVM, Solana, TON and Bitcoin testnets.

The flow

#	Step	Call	You get
1	Discover	GET /api/chains?unwrap=true	FROM chains (isTestnet: false) with their pay target contracts.depository; TO chains (isTestnet: true; skip isEnabled: false) and tokens.
2	Quote	POST /api/quote { chainId, fromToken, sender, toChainId, toToken, recipients[], toAmounts[] }	quoteId, vault (= pay target), fromTotal, deadline, signature. Free, non-binding, valid 180 s.
3	Pay	one transaction on the FROM chain, exactly fromTotal, before deadline	EVM: pay(quoteId, deadline) on vault with msg.value = fromTotal (or payWithToken / payWithTokenPermit). Solana: transfer to vault + SPL memo = quoteId. TON: non-bounceable transfer to vault + comment = quoteId.
4	Track	GET /api/order?from_tx_hash=<ref>	one order per recipient; completed once to.txHash is set. ref = EVM tx hash, Solana signature, or the quoteId on TON.

Endpoints

Endpoint	Purpose
GET /api/chains	Chains, tokens, pay targets.
GET /api/quotes	TO-token rates and dispensable liquidity (not the quote endpoint).
GET /api/prices · /prices/at	Live and historical FROM-token prices.
POST /api/quote	Price and sign a swap.
GET /api/order	Orders of one payment (from_tx_hash) or one order (id); &paginate=1 for big batches.
GET /api/orders	A payer's history, view=batches for one row per payment.
POST /api/orders/status	Bulk status by order id (≤ 500).
GET /api/orders/load	Queue depth and your position (ETA).
GET /api/orders/stream	Server-Sent Events when your orders change.

Numbers to remember

What	Value
Minimum order	$1 single recipient · $5 multisend
TO amount precision	4 decimal places (whole sats on Bitcoin); ≥ 0.001 SOL per recipient on Solana
Quote lifetime	180 s (deadline = expiry)
Recipients per quote	up to 10 000, one payment
Rate limits	600 requests / min per IP · 10 quotes / min per IP · 30 quotes / min per sender
Amounts	base-unit integer strings (toAmounts, fromTotal); order history amounts are human decimals
Native coin	token address 0x0000000000000000000000000000000000000000 on every chain
Non-EVM FROM ids	Solana 1399811149 · TON 1667471768 (Solana testnet 1399811150, devnet 1399811151, TON testnet 1667471769)
Price	TO amount × listed rate, converted at the live Chainlink price; no extra fee. You pay the FROM chain's gas.

Payment rules

Same payer as sender · same token as fromToken · exactly fromTotal · before deadline · one quoteId per payment. Anything else does not become an order — see Payment rules.

When something goes wrong

You see	Meaning	Do
400 BELOW_MIN_TOTAL	order under $1 / $5	raise toAmounts
400 NO_LIQUIDITY / 503 NO_TO_PRICE	that TO token can't be dispensed now	check GET /api/quotes, try later or another token
429 RATE_LIMITED	too many requests / quotes	sleep Retry-After seconds
503 WARMING_UP	backend restarting	retry in retryAfterSec
revert Expired (EVM)	paid after deadline	request a new quote
order failed	payout failed for that recipient	the FROM slice is refunded — see the refund field of the GET /api/order response
no order after paying	paid after deadline, or no usable quoteId in the memo / comment	a refund is recorded — refund on GET /api/order, or your history
no order, no refund	wrong payer / token / amount, or the same quote paid twice	Errors → held for review

Every code with its fix: Errors.
