Base URL: https://api.testnet.topokki.exchange The Topokki API provides current swap quotes, display prices, and testnet configuration. It is public and returns JSON.
This is a testnet API. Quotes and prices can change quickly. Request a fresh quote before every swap.

​
Conventions

  • All token addresses are EVM addresses.
  • Token amounts are raw integer strings. For example, 1000000 is 1 USDC when the token has 6 decimals.
  • Quote requests use GIWA Sepolia chain ID 91342.
  • A successful request returns 200. Invalid inputs return 400; a request that cannot be quoted returns 422.
