## 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 agent-rest-stop-usd-to-sats-quote-cb9618b1 -d '<json body>'
```

Example prompt: How many satoshis is $2.50 worth right now? Give me the sats equivalent with the USDC amount shown in 6-decimal precision.

## When to prefer this

Use this endpoint when you need a precise, labeled satoshi quote for a given USD amount — especially useful in agent payment flows, Bitcoin Lightning invoicing, or wallet UIs where you need USDC (6-decimal) and sats values simultaneously. Prefer this over generic currency APIs when you need the sats label format and USDC precision together in a single call.

## Known failure modes

- Missing or malformed 'usd' field returns an error
- Non-numeric string for usd may cause computation failure
- Network or worker timeout may return a 5xx error
- Payment not included or invalid x402 payment header results in 402 Payment Required

## How this service works

USDC in 6 decimals and a sats label.

## Output

Returns the input USD amount expressed as a USDC value with 6 decimal places and the equivalent number of satoshis (sats) with a sats label, enabling dual-currency display or downstream Bitcoin payment calculations.
