export UNISWAP_API_KEY="your_api_key_here"
Base URL: https://trade-api.gateway.uniswap.org/v1
Required headers for all requests:
Content-Type: application/json
x-api-key: $UNISWAP_API_KEY
x-universal-router-version: 2.0
Get the best price for a token swap. This is the most common operation.
curl -s -X POST https://trade-api.gateway.uniswap.org/v1/quote \
-H "Content-Type: application/json" \
-H "x-api-key: $UNISWAP_API_KEY" \

The above example quotes swapping 1 WETH → USDC on Ethereum mainnet.
Key parameters:
| Parameter | Values |
|---|---|
type | EXACT_INPUT or EXACT_OUTPUT |
slippageTolerance | 0–100 (percentage) |
routingPreference | BEST_PRICE, FASTEST, or CLASSIC |
protocols | Optional: ["V2", "V3", "V4"] |
Response includes quote.output.amount, quote.gasFeeUSD, and routing details.
Tip: Use the
gasFeeUSDfield to display gas costs. Don't manually convertgasFee(wei) — it leads to inaccurate estimates.
Before swapping ERC-20 tokens, check if the token is approved for the Uniswap router.
curl -s -X POST https://trade-api.gateway.uniswap.org/v1/check_approval \
-H "Content-Type: application/json" \
-H "x-api-key: $UNISWAP_API_KEY" \
-H "x-universal-router-version: 2.0" \

"amount": "1000000000",
"chainId": 1
}' | jq .
approval is null — token is already approved, proceed to swap.approval contains a transaction — sign and submit it before swapping.The full swap flow is: check_approval → quote → swap.
After getting a quote, send it to the swap endpoint to get a ready-to-sign transaction:
# Step 1: Get quote (see above)
# Step 2: Send quote response to /swap
curl -s -X POST https://trade-api.gateway.uniswap.org/v1/swap \

Response returns a ready-to-sign transaction with to, from, data, value, and gasLimit.
Important: Spread the quote response into the swap request body — don't wrap it in
{"quote": ...}. Also strip anynullfields likepermitData: nullbefore sending.
