Tool detail
RAVN
Returns a best-price cross-chain swap quote across 20 execution venues and 17 chains, including native Bitcoin, with a quoteToken to pass to /execute.
Categories: Defi
Use when
- get a swap quote between two tokens on different chains
- compare execution venues for a cross-chain Bitcoin swap
- check slippage and output amount before executing a swap
Not for
- not the swap execution itself — this returns a quoteToken for a separate /execute call
- not a price-only preview unless destinationAddress is omitted (then it's non-executable)
Inputs
POST JSON body: { inputChainId, outputChainId, inputToken, outputToken, inputAmount, userAddress } (required); destinationAddress, excludeVenues, rankingMode, slippageBps, sandbox and others (optional)

Other BTC-source venues (Garden, THORChain, Chainflip, Rift) support binding this at execute time instead."

"description": "Test the full quote -> execute -> status flow with no real funds and no live venue settlement. The quote itself is still priced live. On /v1/execute, THORChain BTC-source and Chainflip are unsupported (both can incur a real on-chain cost that can't be sandboxed) and every other venue returns realistically-shaped execution data with no funds moved. /v1/submit-signature skips the real venue submission. /v1/status always reports an immediate synthetic success. Sandbox swaps are never metered or billed."
