# PennyRail Bulk Deterministic Transform Utility

> PennyRail Bulk Deterministic Transform Utility is a paid API for AI agents from pennyrail.vercel.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Executes a batch of deterministic transformation operations on a provided input object and returns the transformed results

## 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 pennyrail-bulk-deterministic-transform-utility-a0cfd1e5 -d '<json body>'
```

Example prompt: Can you run this object through PennyRail's bulk deterministic transform utility — I need multiple standard transformations applied in one batch call: {"records": [{"id": 1, "value": "hello"}, {"id": 2, "value": "world"}]}

## When to prefer this

Choose this endpoint when you need to apply multiple deterministic, reproducible transformations to a structured data object in a single paid micro-transaction call via x402. It is best suited for batch processing workflows where idempotency is required and you want to avoid multiple round-trips. Prefer it over single-transform endpoints when you have several operations to apply to one payload at once.

## Known failure modes

- Missing required 'input' field returns a validation error
- Malformed or non-object input value causes rejection
- Payment not settled via x402 protocol results in 402 Payment Required
- Unsupported transform operations in the batch return partial or empty results
- Overly large input payloads may hit size limits or time out

## How this service works

Machine-readable settlement service

## Output

An object with additional properties containing the results of the deterministic batch transformations applied to the input; the exact shape depends on the transforms requested but will reflect processed/converted versions of the submitted input data
