x402
Base TWAP Price Oracle (Manipulation-Resistant) 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 2026-09-15).
Returns manipulation-resistant TWAP and spot prices for any Base ERC-20 token, computed live from on-chain Uniswap v3 data with deviation and manipulation detection.

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 token's current spot price and TWAP price in the requested quote asset (USDC or WETH), the deviation in basis points between spot and TWAP, a boolean flag if manipulation is suspected, token metadata (symbol, decimals), the block height, the window actually used, and a confirmation that no third-party data was used.
Example use cases
Spot vs TWAP deviation check
“Can you pull the spot price and TWAP for the Base token at 0x4200000000000000000000000000000000000006 in USDC and tell me how many basis points they're drifting apart — I want to know if someone might be manipulating the price right now?”
DeFi trade pre-execution price audit
“Before I execute this swap, grab the on-chain TWAP price for the ERC-20 at 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb quoted in USDC directly from Base chain data — no CoinGecko — and warn me if anything looks off or suspicious.”
Token price integrity security scan
“I'm reviewing this Base token at contract 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA and I need you to fetch its manipulation-resistant TWAP in WETH, check the deviation from spot price, and flag it if the pricing looks like it could be getting gamed by someone.”
Technical details
Endpoint
GEThttps://x402-data-api.bodhinindustries.workers.dev/priceWhen to prefer
Choose this endpoint when you need a trustless, auditable, on-chain price for a Base ERC-20 that cannot be spoofed by third-party data feeds. It is ideal for DeFi agents that need manipulation-resistant pricing, security analysis of token price integrity, or any scenario where you cannot trust centralized price oracles. Prefer it over CoinGecko or CoinMarketCap lookups when on-chain auditability matters.
Side effects
- Token address not found or not a valid ERC-20 on Base — returns error or empty response
- No Uniswap v3 liquidity pool exists for the token — unable to compute TWAP
- Window parameter out of range (below 60 or above 7200) — may return validation error
- Token has insufficient liquidity for reliable TWAP — manipulationSuspected may be true
- Network or RPC errors on Base chain — transient 5xx response
- Payment not provided or insufficient — 402 Payment Required
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| quote | string | Quote currency: 'usdc' (default) or 'weth'. |
| tokenrequired | string | Base ERC-20 contract address to price. |
| window | integer | TWAP averaging window in seconds (60–7200, default 1800). Longer = more manipulation-resistant. |
