# Pons Trading API > Trade and launch tokens on Pons, on Robinhood Chain shrine.trade's free, keyless HTTP + WebSocket API for Pons - the launchpad on Robinhood Chain (chain id 4663, an Ethereum L2). Buy and sell any Pons token: v2 (bonding curve, then Uniswap v4 after graduation) or v1 (Uniswap V3 from launch). Launch new tokens on Pons v2. Every endpoint returns unsigned EIP-1559 transactions the caller signs and sends themselves; the API never holds keys or funds. Key facts: - Base URL: https://api.shrine.trade/rh (WebSocket: wss://api.shrine.trade/rh/api/launches/ws) - Auth: none. Limits: 5 requests/second per IP per endpoint, 2 launch-feed connections per IP (HTTP 429 beyond). - Amounts on a buy are always ETH; tokens priced in USDG, NVDA, TSLA or another tokenised asset are converted automatically. Sells can convert back to ETH with `toEth: true`. - Fee: 1% per trade to shrine.trade, taken in the asset the trade settles in. Launching and reads are free. Pons's own curve fee, creator tax and opening snipe tax apply on top. - Responses carry `txs`: sign each with the wallet in `from` and POST the signed hex to /api/send as `{ "signedTx" }`, in order - no RPC needed. Errors are `{ "error": code, "message": text }`. - Full text of every page: https://shrine.trade/pons/llms-full.txt ## Docs - [Robinhood Chain Trading API - Pons, Flap, Bags, o1 and every launchpad](https://shrine.trade/pons/index.md): Build bots that trade tokens from every launchpad on Robinhood Chain - Pons, Flap, Bags, o1, Pools.trade, PAIR, Long, letscash - and any Uniswap pool, through one free, keyless API.
