# Cooking Calculators – USDA Roast Times

> Cooking Calculators – USDA Roast Times is a paid API for AI agents from cooking-calc.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-29).

Returns USDA-sourced oven roasting time ranges (low and high, in hours and minutes) for turkey, beef rib roast, pork loin, and lamb leg, given the food type and weight in pounds.

## 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 cooking-calculators-usda-roast-times-ad96d1f7
```

Example prompt: How long should I roast an unstuffed 18-pound turkey? Give me the USDA time range and the recommended oven temperature.

## When to prefer this

Choose this endpoint when you need USDA-authoritative roasting time estimates for whole turkey, turkey breast, beef rib roast, pork loin, or lamb leg — particularly for meal planning or food-safety guidance. It covers only these specific roasts; for cooking temperatures alone use a dedicated internal-temperature endpoint, and for non-roast cooking methods (grilling, braising) look elsewhere.

## Known failure modes

- Weight outside 1–30 lb range may return degraded or out-of-table results
- Invalid 'food' enum value returns an error
- Missing required queryParams (food or weightLb) returns a validation error
- 'stuffed' parameter ignored if food is not whole turkey
- 'cut' parameter ignored if food is not turkey-breast

## How this service works

USDA roasting time guides: turkey (stuffed or not, by weight), beef rib roast, pork loin and leg of lamb. Guides, not doneness.

## Output

Returns a structured object including the food name, weight, oven temperature in both Fahrenheit and Celsius, a roasting time range (hours and minutes, low and high), the USDA target internal temperature, a plain-English summary, source attribution, and a food-safety disclaimer. May include a 'degraded' flag and reasons if the weight is outside the USDA table range.
