The Intents API is the integrator-facing interface for requesting quotes, submitting orders, and tracking status. All endpoints are open and require no API key.
For solver-facing endpoints (quote submission, account management), see the Solver API Overview. For authentication details, see Authentication.

Endpoints

MethodPathDescription
POST/quote/requestRequest a quote for an intent (exact-input or exact-output)
GET/api/v1/integrator/quote/requestV1 quote endpoint for integrator-friendly quote parameters
POST/orders/submitSubmit an order (intent) to the solver network
GET/ordersList orders with optional filters
GET/orders/statusGet order status by onChainOrderId or catalystOrderId
GET/chains/supportedGet the list of supported chains
GET/routesGet supported routes (chain/asset pairs)

​
Order Lifecycle

Orders can include transitional states depending on submission path and indexing timing. In most integrations, the primary execution progression is: 
Signed → Delivered → Settled
StatusWhat happened
SignedOrder signed and broadcast to the solver network
DeliveredSolver has delivered assets on the destination chain
SettledOracle verified delivery, locked funds released to solver
If the order is not filled before fillDeadline, it can be refunded after expires.

​
Interoperable Addresses

The Intents API uses EIP-7930 interoperable addresses, which encode both the chain and address in a single bytes field. This applies to user, asset, and receiver fields in quote requests. Example encoding of 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base (chain ID 8453): 
0x0001|0000|02|2105|14|833589fCD6eDb6E08f4c7C32D4f71b54bdA02913
  ^^^^  Version: 1
       ^^^^  ChainType: EVM
            ^^  Chain Reference length: 2 bytes
               ^^^^  Chain Reference: 8453 (hex 2105)
                    ^^  Address length: 20 bytes
                       ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^  Address

​
Amounts

All amounts are in the token’s smallest unit (wei-equivalent), with no decimals. For example, 1.5 USDC (6 decimals) is "1500000".
