Base Multicall Onchain Data Executor
x402
Base Multicall Onchain Data Executor 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).
Executes batched raw calldata against multiple Base chain contract addresses in a single request, returning raw hex return data for each call, all computed live from the Base blockchain with no third-party data.

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
An array of results per call, each containing the target address, its positional index, a success boolean, raw 0x-hex return data to decode client-side, an emptyReturn flag, and the byte length of the return. Also returns the pinned block number, count of valid calls executed, any skipped calls with reasons (invalid_address or invalid_data), the Multicall3 contract address used, and a timestamp. thirdPartyDataUsed is always false.
Example use cases
Wallet approval risk audit
“Audit my wallet 0xAbCd...1234 for risky token approvals — batch check the allowances it has granted to the Uniswap router at 0x2626...7F73 and the Permit2 contract at 0x000000000022...90aB for USDC at 0xA0b8...eB48, WETH at 0x4200...0006, and DAI at 0x50c5...3Da2, all in one live Base chain request with no third-party data.”
Live TWAP price oracle check
“Fetch me manipulation-resistant TWAP prices for USDC/ETH and WBTC/ETH on Base — batch the raw calldata reads against the relevant Uniswap V3 pool contracts in a single request, pulling everything live from Base chain with no external price feeds.”
ERC-20 token safety scan
“Do a full safety scan on this new Base token at 0xDead...BeeF — batch check its total supply, owner address, whether it has a blacklist or pause function, and the top wallet's balance all in one call, reading everything live from the Base blockchain without any third-party indexers.”
Technical details
Endpoint
GEThttps://x402-data-api.bodhinindustries.workers.dev/multicallWhen to prefer
Choose this endpoint when you need to batch multiple raw EVM calldata reads against Base chain contracts in a single HTTP call with no reliance on third-party indexers or price feeds. Ideal for agents performing onchain token safety scans, wallet approval audits, TWAP price checks, or contract intel queries that require live, self-computed Base chain data. Prefer over single-call endpoints when combining multiple contract reads to minimize latency and cost.
Side effects
- Individual sub-calls may revert (success: false) if the contract call fails or the address has no matching function
- Calls with malformed addresses or invalid calldata hex are skipped and listed in the skipped array with a reason
- Requesting more than 20 addresses in one call may exceed limits
- Empty calldata defaults to 0x but may yield emptyReturn: true
- Network-level failures from the Base RPC or Cloudflare Worker may result in a 5xx error
