## OpenAPI

openapi: 3.1.0

  title: Portal Client API
  version: '3.0'
  description: >
    The Portal Client API provides endpoints for managing wallets, building
    transactions,

    and interacting with blockchain networks. All endpoints require
    authentication via a

    Client API Key or Client Session Token (CST) passed as a Bearer token.


    ## Base URL

    `https://api.portalhq.io/api/v3`


    ## Authentication

    Include your Client API Key or Client Session Token as a Bearer token in the

    `Authorization` header of every request.


    ## Chain ID Format

    Chain parameters use either friendly names (e.g. `ethereum`, `solana`) or
    CAIP-2 format

    (e.g. `eip155:1`, `solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp`). When using
    CAIP-2 format

    in URLs, ensure the colon is URI-encoded (`%3A`).
