The LI.FI Intents API has two access levels: open integrator endpoints and authenticated solver endpoints.

Integrators

Integrator endpoints are fully open. No API key, no registration, no rate limits. You can start building immediately.

Endpoints

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

Solvers (API Key Required)

Solver endpoints require an API key passed via the api-key header. These endpoints are used for submitting quotes, managing solver accounts, and tracking reputation.
MethodPathDescription
POST/quotes/submitSubmit or update up to 200K solver quotes
GET/solver-api/quotesGet solver’s uploaded quote inventory
GET/solver-api/solver/identitiesGet solver identities for reputation tracking
POST/solver-api/account/registerRegister a solver account
POST/solver-api/account/unregisterUnregister a solver account

Authenticating Requests

Pass your API key in the api-key header:
curl -X POST 'https://order.li.fi/quotes/submit' \
  -H 'Content-Type: application/json' \
  -H 'api-key: YOUR_SOLVER_API_KEY' \
  -d '{ ... }'

Getting an API Key

Register and manage your solver API key in the solver UI:
