# Base44 Deterministic Utility Batch Worker

> 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.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability base44-deterministic-utility-batch-worker-88c3ec1f -d '<json body>'
```

Example prompt: Can you run two utility operations in one batch: first convert 26.2 miles to kilometers, and then normalize the HTTP version string 'h2' to its canonical form?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
