Quickstart

The StockKit API is live at https://api.stockkit.dev. It is open during the beta: no API key required.

Get a price

curl https://api.stockkit.dev/v1/prices/NVDA

{
  "symbol": "NVDA",
  "currency": "USD",
  "underlying": { "bid": "228.5", "ask": "229.52", "mid": "229.010000" },
  "token": { "bid": "228.500000", "ask": "229.520000", "mid": "229.010000", "multiplier": "1.000000000000000000" },
  "halted": false,
  "asOf": "2026-09-05T14:50:45Z"
}

Get an executable quote

Quotes come from live Uniswap v3 pools on Robinhood Chain (chain ID 4663), quoted against USDG:

curl "https://api.stockkit.dev/v1/quote?symbol=NVDA&side=buy&amount=100&denom=usd"

{
  "symbol": "NVDA",
  "side": "buy",
  "feeTier": 500,
  "usdAmount": "100.000000",
  "tokenAmount": "0.432324841419642912",
  "effectivePricePerToken": "231.307550",
  "venue": "uniswap-v3"
}

Build a trade

StockKit is non-custodial: /v1/trade/build returns unsigned transactions that you review and sign with your own wallet. StockKit never holds keys and never executes trades.

curl -X POST https://api.stockkit.dev/v1/trade/build \
  -H "content-type: application/json" \
  -d '{
    "symbol": "NVDA",
    "side": "buy",
    "amount": "100",
    "denom": "usd",
    "recipient": "0xYourWalletAddress",
    "slippageBps": 50
  }'

The response contains an optional ERC-20 approval step and the Uniswap SwapRouter02 swap call, with slippage bounds already applied. Submit the steps in order from your wallet or app.

TypeScript / JavaScript SDK

npm install @stockkit/sdk

import { StockKit } from "@stockkit/sdk"

const stockkit = new StockKit()

const price = await stockkit.prices.get("NVDA")

const quote = await stockkit.trade.quote({ ticker: "NVDA", amount: 100 })

const tx = await stockkit.trade.build({
  ticker: "NVDA",
  amount: 100,
  recipient: "0xYourWalletAddress",
})

// Hourly candles from the onchain pool price
const { candles } = await stockkit.history.get("NVDA", { interval: "1h" })

// Supply, pool TVL, and the DEX premium vs the equity quote
const stats = await stockkit.stats.get("NVDA")

Every response is fully typed, and errors throw StockKitError with status and code. Source: github.com/stockkit-labs/sdk.

The API is also plain JSON over HTTPS with open CORS, so fetch works directly from any runtime or browser without the SDK.

From Python

import requests

BASE = "https://api.stockkit.dev/v1"

price = requests.get(f"{BASE}/prices/NVDA").json()

quote = requests.get(f"{BASE}/quote", params={
    "symbol": "NVDA", "amount": 100
}).json()

tx = requests.post(f"{BASE}/trade/build", json={
    "symbol": "NVDA", "amount": "100",
    "recipient": "0xYourWalletAddress"
}).json()
