Launchpad API

The Launchpad API is a backend service that indexes blockchain events from the Launchpad and AMM contracts into a TimescaleDB database. It provides fast, pre-formatted REST endpoints and real-time Server-Sent Events (SSE) for frontends and bots.

Why Use This Instead of Chain API?

The Chain API (port 1317) gives you raw blockchain state. The Launchpad API gives you pre-indexed, enriched data that’s ready to display:
NeedChain APILaunchpad API
List all tokens with pricesQuery each contract individuallyGET /api/tokens — one call
Trade history for a tokenSearch events, parse wasm logsGET /api/trades/recent?token_address=...
OHLCV candlestick chartsNot availableGET /api/candles/:address
Real-time trade feedWebSocket + event parsingGET /api/sse/feed — ready-to-use events
Token 24h volumeAggregate from raw tradesPre-computed in token response

​
Authentication

All endpoints are public. No API key required.

Data Sources

The API indexes events from two on-chain contracts:
SourceContractEvents Indexed
LaunchpadBonding curve contracttoken_created, buy, sell, buy_and_graduate, graduate
AMMConstant-product DEXswap (both directions)
The indexer polls the chain every ~5 seconds and writes all events atomically to the database. OHLCV candles are computed automatically by TimescaleDB continuous aggregates at 1-minute, 5-minute, 1-hour, and 1-day intervals.
