​
API Overview

The Kroko DEX provides a REST API for swap routing, price quotes, pool data, and token information. The API handles complex routing logic off-chain and returns ready-to-use transaction calldata.

​
Base URL

All endpoints below are relative to the base URL above.

​
Authentication

No authentication is required. The API is currently publicly accessible.
Authentication may be introduced in the future. If you are building a long-lived integration, check back here periodically for updates.

​
Common Patterns

​
Request Format

  • GET endpoints use query parameters
  • POST endpoints accept JSON body with Content-Type: application/json

​
Response Format

Successful responses return JSON directly. Error responses follow this format:

​
Token Amounts

All token amounts are in raw units (wei). For a token with 18 decimals: Convert with: rawAmount = humanAmount × 10^decimals

​
Token Addresses

Always use checksummed or lowercase ERC-20 addresses. For native KAS, use the WKAS address (not the zero address).

Rate Limits
