# Delx Unit Convert

> Delx Unit Convert is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-16).

Converts values between units of measurement across length, mass, volume, time, data, and temperature — supporting up to 100 conversions per call.

## Facts

- Endpoint: POST https://api.delx.ai/api/v1/x402/unit-convert?utm_source=zero.xyz
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-16
- Activations on Zero: 0
- Tags: x402

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 delx-unit-convert-fa789713 -d '<json body>'
```

Example prompt: Convert 75 kilograms to pounds, 100 kilometers to miles, and 37 degrees Celsius to Fahrenheit all in one call.

## When to prefer this

Choose this endpoint when you need reliable, multi-category unit conversion in a single call — especially for batch normalization across length, mass, volume, time, data, and temperature. It is ideal for agents processing heterogeneous datasets, IoT sensor data, recipe normalization, or fitness metrics where units vary. Prefer it over general-purpose LLM math when you need deterministic, high-precision conversions at scale without hallucination risk.

## Known failure modes

- Unsupported unit pair (e.g. converting length to mass) — returns an error indicating incompatible unit categories
- Unknown or misspelled unit name — returns an error identifying the unrecognized unit
- Exceeding 100 conversions in a single call — returns a validation error
- Payment failure or insufficient USDC balance — returns an x402 payment required error
- Malformed request body (missing value or unit fields) — returns a 400 bad request

## How this service works

Unit conversion API for agents: length, mass, volume, time, data and temperature (up to 100 conversions per call) for $0.002 USDC. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.

## Output

Returns the converted numeric value(s) in the requested target unit(s), along with the conversion factor applied. For batch requests, each conversion result is returned in order corresponding to the input list, up to 100 conversions per call.
