How this service works
Uniswap V3 position by NFT id on 5 chains: owner, pool, price range, whether it is in range, token amounts, fee tier and uncollected fees.
Output
Returns a JSON object with the chain name and chain ID, the NFT position ID, the pool address, the owner's wallet address, token0 and token1 details (symbol, address, decimals), the price range as tick lower and upper, whether the position is currently in range, current token amounts, fee tier percentage, uncollected fees for each token, liquidity, whether the position is closed, the data source, and a plain-language note summarizing the result in human-readable form.
Example use cases
Monitor LP position range status
“Check my Uniswap V3 position with NFT ID 78234 on Ethereum — is it still in range, and what are the current token amounts?”
Audit uncollected fees before harvest
“Look up Uniswap V3 LP position #15502 on Polygon and tell me how much in uncollected fees I've accumulated and what the fee tier is.”
Verify ownership of a position NFT
“Who currently owns Uniswap V3 position NFT number 3301 on Base, and what pool is it in?”

Endpoint
GEThttps://saylorinnovations.com/api/chain/uniswap-v3-position?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need detailed, structured data about a specific Uniswap V3 liquidity position by NFT ID across Ethereum, Polygon, Arbitrum, Optimism, or Base — particularly when you need in-range status, uncollected fees, token amounts, and owner in a single call without building your own multi-chain RPC infrastructure.
Side effects
- Invalid or non-existent token_id returns null fields or an error response
- Unsupported chain name/ID returns an error
- Position NFT burned or transferred may return unexpected owner
- Network RPC errors may cause transient failures
- Closed positions (zero liquidity) return closed=true with null in_range
