## 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 scriptmasterlabs-acp-x402-calculator-e51ebe6d
```

Example prompt: Can you run a calculation using the ScriptMasterLabs x402 calculator endpoint and return me the result — I'll pay the $0.001 USDC fee on Base via x402?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call calculation settled natively in USDC on Base via the x402 protocol, particularly in crypto-native or RWA-adjacent workflows where micro-payment infrastructure is already in place. Less suitable when calculation requirements are precisely specified in advance and a free or self-hosted calculator is available.

## Known failure modes

- Payment not settled — x402 payment failure returns 402 status requiring USDC on Base
- Invalid or missing properties parameter returns an error
- Service unavailable on Render free tier cold start — expect timeout on first call
- Malformed input schema returns 400 or empty result
- Undocumented response shape may require parsing of arbitrary JSON

## How this service works

Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).

## Output

Returns a computed result object; the exact shape depends on the input properties passed. Typically a JSON payload with the calculation output. Response schema is currently sparse (empty example object), so the agent should expect a flexible JSON result.

## Request schema (JSON Schema)

```json
{
 "type": "object",
 "properties": {
  "properties": {
   "type": "string"
  }
 }
}
```

## Response schema (JSON Schema)

```json
{
 "example": {}
}
```
