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:

Need	Chain API	Launchpad API
List all tokens with prices	Query each contract individually	`GET /api/tokens` — one call
Trade history for a token	Search events, parse wasm logs	`GET /api/trades/recent?token_address=...`
OHLCV candlestick charts	Not available	`GET /api/candles/:address`
Real-time trade feed	WebSocket + event parsing	`GET /api/sse/feed` — ready-to-use events
Token 24h volume	Aggregate from raw trades	Pre-computed in token response

Authentication

All endpoints are public. No API key required.

Rate Limits

Window	Max Requests

Available Endpoints

Section	Endpoints
List Tokens	All indexed tokens with metadata, prices, and 24h stats
Token Detail	Single token by contract address
Trades	Recent trades, filterable by token
Candles	OHLCV candlestick data (1m, 5m, 1h, 1d)
SSE Feed	Real-time trade, launch, and graduation events
Wallet	Balance, token holdings, transaction history, and broadcast

Data Sources

The API indexes events from two on-chain contracts:

Source	Contract	Events Indexed
Launchpad	Bonding curve contract	`token_created`, `buy`, `sell`, `buy_and_graduate`, `graduate`
AMM	Constant-product DEX	`swap` (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.
