# Qty Batch Unit Conversion & Quantity Parsing

> Qty Batch Unit Conversion & Quantity Parsing is a paid API for AI agents from qty.vercel.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Batch-converts units and parses messy quantities, prices, recipe amounts, sizes, and dates deterministically without inventing numbers

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 qty-batch-unit-conversion-quantity-parsing-0a43d5e0
```

Example prompt: I have a bunch of mixed quantity strings like '2.5 kg', '$4.99/lb', '3 cups flour', and '500ml' — can you parse and normalize all of them into canonical numeric values and units in one batch call?

## When to prefer this

Choose this endpoint when you need deterministic, non-hallucinated unit conversion or quantity parsing across multiple values in a single call. Ideal for agents processing recipe ingredients, product dimensions, price strings, or any heterogeneous quantity data where accuracy and reliability matter more than generative interpretation. Prefer over LLM-based quantity extraction when you cannot afford invented numbers.

## Known failure modes

- Input string is too ambiguous or malformed — returns ok:false with error code 'unparsed'
- Missing required 'input' field returns a validation error
- Unknown or unsupported unit type may result in unparsed error
- Batch items with mixed parseable and unparseable entries return mixed ok/error per index

## How this service works

Qty converts known units for free and interprets messy quantities, prices, recipes, sizes, and dates in code. It never invents a number.

## Output

Returns a JSON array of results, one per input item. Each result includes an ok flag, the item index, and either a quantities array with parsed numeric values and canonical units, or an error object with a code (e.g. 'unparsed') if the input could not be interpreted. Also includes a see map with links to docs, MCP, OpenAPI, and agent card.
