API Reference

REST API for direct integration. All endpoints require authentication unless noted.

Authentication

Every request must include an Authorization header with a valid API key. Keys are prefixed with wk_live_ for production and wk_test_ for development.

Base URL: https://api.wikichain.ai

Rate limit: 120 requests/minute (30/min for RPC)

bash
curl https://api.wikichain.ai/api/agents \
  -H "Authorization: Bearer <YOUR_API_KEY>"

Response format

All responses are JSON-encoded and wrapped in a data envelope. Errors return an error string instead.

// Success
{ "data": { ... } }

// Error
{ "error": "Description of what went wrong" }
