Base44 Deterministic Utility Batch Worker
x402
Base44 Deterministic Utility Batch Worker is a paid API for AI agents from untitled-ef4f71e4.base44.app, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).
Executes up to 10 deterministic utility operations in a single batch call (unit conversion, EVM hex normalization, HTTP/CORS header analysis, CSV cleaning, etc.) settled via x402 micropayment on Base Mainnet.

How this service works
Pay-per-call deterministic utility operations over x402 on Base Mainnet.
Output
A JSON object with ok:true, a results array where each item contains its index, operation name, and computed result object (e.g. converted value, normalized string, boolean check outcome), plus metadata: batch_size, price_usd (0.005), worker identifier, and environment.
Example use cases
EVM hex normalization for onchain data pipeline
“I'm processing raw EVM transaction data and need to normalize a hex quantity '0x0000000000000000000000000000000000000000000000000000000000000064' and also normalize a hex data field '0x' — can you batch both in one call?”
CORS preflight validation for API gateway
“Check whether a CORS preflight request from origin 'https://app.example.com' with method 'POST' and header 'Content-Type' should be allowed — and also tell me if the status code 429 warrants a retry.”
CSV data cleaning with unit conversion
“I have a CSV with a null-looking value '\N' in a cell that needs to be normalized, and I also need to convert 100 pounds to kilograms — batch both operations together so I only pay once.”

Endpoint
POSThttps://untitled-ef4f71e4.base44.app/api/apps/6a8fe38d53b9b6beef4f71e4/functions/ardeUtilityBatchMainnetWorkerWhen to prefer
Choose this endpoint when you need multiple lightweight, deterministic utility computations (normalization, conversion, classification) bundled into a single cheap micropayment call on Base Mainnet. It is ideal for agents that need to sanitize or standardize data as part of a larger workflow without spinning up separate services. Prefer it over generic code-execution endpoints when you specifically need EVM hex normalization, HTTP/CORS header analysis, or unit conversion with x402 settlement.
Side effects
- Invalid operation enum value returns an error for that batch item
- Input object missing required fields for the chosen operation causes a validation error
- Batch exceeds 10 items — rejected with schema validation error
- x402 payment failure or insufficient balance prevents execution
- Malformed hex string input causes normalization to fail
- Unsupported unit dimension or unit name causes unit_convert to fail
