How this service works
Self-computed Base onchain toolkit for AI agents: ERC-20 safety scan, manipulation-resistant TWAP price oracle, gas/fee oracle, calldata decoder, token/address/contract intel, wallet approval-risk audit, and batch token triage — all computed live from raw Base chain, no third-party data.
Output
Returns a JSON object with the position's pool address, fee tier, token0 and token1 addresses and symbols, raw liquidity, tick lower/upper, current tick, whether the position is in range (below_range | in_range | above_range), uncollected fees for both tokens, position owner address, and the Base block height at which data was computed. All data is sourced directly from the Base chain with no third-party data dependencies.
Example use cases
Example prompt
“Check my Uniswap v3 position on Base — token ID 123456 — and tell me if it's currently in range, how much uncollected fees I have in both tokens, and what the tick bounds are.”

Endpoint
GEThttps://x402-data-api.bodhinindustries.workers.dev/positionWhen to prefer
Use this endpoint when you need live, chain-direct Uniswap v3 position data on Base without relying on third-party indexers like The Graph or Alchemy. Ideal for agents that need trustless, manipulation-resistant position status — especially for fee harvesting decisions, rebalancing triggers, or LP health checks.
Side effects
- Invalid or non-existent tokenId returns an error or empty/null fields
- tokenId that belongs to a different chain (not Base) returns incorrect or null data
- Payment failure (x402) if USDC payment is not properly attached
- Network or RPC timeout if Base chain is temporarily unreachable
- tokenId provided as hex instead of decimal may fail validation
