Eurybia API Documentation
Eurybia is a Web3 data platform. It exposes three API services with different responsibilities:
| API | Type | Base URL | Auth | Status |
|---|---|---|---|---|
| Open Query API | Data query (read-only) | https://eurybia.xyz/api/open/query | X-API-Key | 🟢 Active |
| Kolect API | Computation (backtest / sentiment / leaderboard) | https://eurybia.xyz/kolect/api | Bearer (query only) | 🟢 Active |
| Quant_Strategy | Quant factor & backtest | — (never deployed) | — | 🔴 Deprecated |
Which API should I use?​
- Query raw / cleaned on-chain, social and market data → use the Open Query API. It serves Twitter, Telegram, news, market OHLCV, Solana token data and historical ClickHouse datasets.
- Run a KOL strategy backtest, get sentiment, or the KOL leaderboard → use the Kolect API.
- Quant_Strategy is deprecated and was never deployed — do not build against it.
Interactive references​
Each API has an interactive OpenAPI reference (Scalar) where you can explore endpoints and try requests:
- Open Query API reference — 21 public endpoints
- Kolect API reference — computation endpoints
- Quant_Strategy reference — archived spec (deprecated)
API keys​
- Open Query: self-service apply at
POST /api/open/query/auth/apply(encrypted payload exchange). See the Open Query guide. - Kolect:
POST /kolect/api/key_requestfor self-service key application; the sentiment query endpoint requires a Bearer key.
Base platform​
- Website: https://eurybia.xyz
- All APIs are read-mostly; heavy queries are backed by PostgreSQL and ClickHouse.
