# Kilogram per Cubic Meter to Pound per Cubic Foot Density Converter

> Kilogram per Cubic Meter to Pound per Cubic Foot Density Converter is a paid API for AI agents from x402-agent.kariguetoazul.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-13).

Converts a density value from kilograms per cubic meter (kg/m³) to pounds per cubic foot (lb/ft³) using IEEE-754 double precision arithmetic.

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 kilogram-per-cubic-meter-to-pound-per-cubic-foot-density-converter-5b3667bc
```

Example prompt: Convert a density of 1025 kilograms per cubic meter to pounds per cubic foot for me.

## When to prefer this

Choose this endpoint when you need a fast, precise, single-call density conversion from kg/m³ to lb/ft³ without setting up a local conversion library. Especially useful in agent workflows where the result needs to be verifiable, deterministic, and audit-logged via a paid x402 micropayment. Prefer over generic unit-conversion APIs when you specifically need this density unit pair and want IEEE-754 double precision guarantees.

## Known failure modes

- Missing or non-numeric 'value' query parameter returns an error
- Negative value rejected (minimum is 0 per schema)
- Value exceeding 1e+100 rejected by schema validation
- Non-GET HTTP method returns 405 or similar
- Payment not provided or insufficient USDC (x402 payment required)
- Network timeout from Cloudflare Worker cold start

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

A JSON object containing the original value and unit (kilogram-per-cubic-meter), the converted value in pound-per-cubic-foot (as an IEEE-754 double), the dimension label ('density'), and the precision used. Example: {"from":"kilogram-per-cubic-meter","to":"pound-per-cubic-foot","value":123.45,"converted":7.706731733125052,"dimension":"density","precision":"IEEE-754 double"}.
