## 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-json-validate-33016c60
```

Example prompt: Can you validate this JSON for me — check whether it has the right properties: {"name": "Alice", "age": 30, "email": "alice@example.com"}?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call JSON validation check settled in USDC on Base via x402, especially in agentic or micropayment-native workflows where spinning up a dedicated validation service is overkill. It is well-suited for spot checks in pipelines that already use the ScriptMasterLabs x402 ecosystem.

## Known failure modes

- Malformed input JSON causes parse error with no validation result
- Missing or empty properties parameter results in ambiguous validation
- Service unavailable on Render cold start causing timeout
- Payment failure (insufficient USDC balance on Base) blocks the call
- Overly complex nested schemas may not be fully supported given minimal schema spec

## 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 validation result indicating whether the provided JSON conforms to the specified properties schema, including any error details or conformance status for each property checked.
