x402
Base Onchain TWAP Quote & Swap Price Oracle is a paid API for AI agents from x402-data-api.bodhinindustries.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).
Returns a manipulation-resistant TWAP-based swap quote between two Base ERC-20 tokens, computed live from raw Base chain data with no third-party dependencies.

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 the expected output token amount (amountOut), execution price (tokenOut per tokenIn), price impact in basis points, whether the price impact warning threshold (>=300 bps) is triggered, the best Uniswap v3 fee tier, human-readable route, current Base block height, and computation timestamp — all derived live from on-chain state with no third-party data.
Example use cases
Example prompt
“How much USDC would I get if I swap 500 WETH (0x4200000000000000000000000000000000000006) for USDC (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base right now — and is the price impact more than 3%?”
Technical details
Endpoint
GEThttps://x402-data-api.bodhinindustries.workers.dev/quoteWhen to prefer
Use this endpoint when you need a trustless, manipulation-resistant swap quote on Base that is computed entirely from raw on-chain data (no third-party price feeds). It is ideal for agents that need to verify price impact before submitting a trade, confirm the best Uniswap v3 fee tier, or audit a quote without relying on CoinGecko, CoinMarketCap, or any external oracle. Prefer it over off-chain price APIs when on-chain accuracy and TWAP resistance to flash-loan manipulation are required.
Side effects
- Invalid or non-ERC-20 token address returns an error or empty route
- Token pair with no Uniswap v3 liquidity pool returns no route
- amountIn of zero or non-numeric string causes a parsing error
- Extreme price impact on illiquid pairs may produce unreliable quotes
- Network latency on Base RPC may occasionally delay block-level freshness
