Authentication

Send an operator-issued API key as a bearer token:

Authorization: Bearer <your-api-key>

Never put a key in a URL. Browser clients may exchange a bearer credential through POST /v1/session; the response sets a secure, HTTP-only, same-origin session cookie for later API requests and WebSocket handshakes.

Keys are issued by the service operator. Contact the operator to request access; there is no self-service signup.

List supported chains

curl --fail-with-body \
  -H 'Authorization: Bearer <your-api-key>' \
  'https://lowcapsxyz.com/v1/chains'

Request a token quote

Replace the chain ID and token address with the asset you need:

curl --fail-with-body \
  -H 'Authorization: Bearer <your-api-key>' \
  -H 'Accept: application/json' \
  'https://lowcapsxyz.com/v1/quote/token/8453/0x1111111111111111111111111111111111111111'

See Errors and response states before treating a successful HTTP response as a priced result.
