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 signaldesk-ai-gram-to-microgram-converter-66dd05e1
```

Example prompt: Convert 123.45 grams to micrograms for me — I need the exact IEEE-754 double-precision result.

## When to prefer this

Use this endpoint when you need a reliable, on-demand gram-to-microgram conversion with IEEE-754 double precision guarantees, especially in automated agent pipelines that require verifiable numeric output for scientific, pharmaceutical, or nutritional calculations where floating-point accuracy matters.

## Known failure modes

- Missing or non-numeric 'value' query parameter returns a validation error
- Negative input value rejected (minimum is 0)
- Values exceeding 1e+100 are out of range and will be rejected
- Payment failure or insufficient USDC balance returns a 402 error
- Network timeout on the Cloudflare Worker edge

## 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 in grams, the converted value in micrograms (multiplied by 1,000,000), the source unit ('gram'), the target unit ('microgram'), the dimension ('mass'), and the precision standard ('IEEE-754 double').
