by JAW.id Cross-Chain Swap in Onchain & crypto

x402 APIPassing, checked 24 min ago

Cross-chain swap quote over NEAR Intents (Aurora). Returns the deposit transaction to sign on the origin chain; the deposit address is the part of quoteId after "aurora:". After sending it, POST /proxy/v2/move-asset/deposit/submit with provider=aurora, the deposit address and the tx hash, then poll GET /proxy/v2/move-asset/deposit/status with provider=aurora and the deposit address. Both are free.

Call it from code
