RAVN tools (10, 3 write)
write = sends, deletes, buys or postsravn_btc_coverageFreeFor a swap where native BTC is the source, not every token on the destination chain is reachable. Returns which of ravn_tokens's list on `chainId` a BTC venue can actually route to, and how many venues serve each, so you can build a token list that matches what will really quote instead of discovering it one NO_LIQUIDITY at a time. BTC-as-source only — selling a token INTO BTC isn't restricted the same way (nearly any token can be sold into BTC), so this has nothing useful to say about that direction.
ravn_btc_prepare_sendwrite actionFreeTurns a DEPOSIT-type ravn_execute result (depositAddress + depositAmount) into a ready-to-sign PSBT, so you don't have to write your own UTXO selection and fee-estimation code. Fetches your UTXOs and the current network fee rate from mempool.space (public, no auth). RAVN never sees or touches a private key — sign the returned PSBT with your own wallet and broadcast it yourself. Only one signer is ever needed (unlike PSBT flows that require coordinating signatures across multiple UTXO-holding wallets), because every RAVN BTC-source venue resolves to a plain single-recipient payment.
ravn_chainsFreeEvery chain RAVN lists a token registry for (see ravn_tokens). Static, doesn't change per request, safe to cache instead of hardcoding a chain table.
ravn_executewrite actionFreeTurn a quoteToken from ravn_quote into an execution payload. Returns one of three shapes (executionType): TRANSACTION (sign and broadcast yourself), SIGNATURE (sign, RAVN submits), or DEPOSIT (send the input asset to a given address). RAVN never takes custody of funds — you always sign or send from your own wallet. TRANSACTION and SIGNATURE may also include an `approval` — an ERC-20 approve() you must broadcast and wait to be MINED before the transaction/signature, or it fails (reverts on TRANSACTION; on SIGNATURE the order is accepted and silently never fills). Only present when the sold token needs it — omitted for native-coin sells and already-approved tokens.
ravn_healthFreeLiveness check across every venue RAVN routes through — call before a swap if you want to know whether a route is degraded ahead of time.
ravn_quoteFreeGet a swap quote from RAVN — same-chain or cross-chain, across 17 chains including native (non-wrapped) Bitcoin and Solana as source or destination. Free, no API key or payment required. Returns a quoteToken; pass it to ravn_execute to get a signable/broadcastable execution payload.
ravn_statusFreePoll the status of a swap by its quoteToken and the ref returned by ravn_execute (deposit address for DEPOSIT venues, statusRef for SIGNATURE venues). Status is authoritative where the venue exposes it; Jupiter is the one live venue that reports 'unknown' honestly rather than guessing.
ravn_submit_signaturewrite actionFreeFor a SIGNATURE-type ravn_execute result only: submit the signature(s) you collected (over typedData, and approvalData if present) to actually place the order. RAVN decodes the venue from quoteToken and routes to the right venue-specific submit path — you never touch a per-venue endpoint. Returns a statusRef — pass it to ravn_status as `ref` to poll this swap.
ravn_tokensFreeRAVN's own listed token registry for one chain — populate a token picker without hardcoding one. This is "what RAVN knows about and might route", not a per-pair routability guarantee for any specific pair; call ravn_quote to check that.
ravn_tokens_resolveFreeResolve an arbitrary token address to its metadata (symbol, name, decimals) via an on-chain read — for a paste-any-address flow, when the token isn't necessarily on ravn_tokens's list.
