## 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 grokzilla-research-skill-x402-micropayment-microservice-4f893de7 -d '<json body>'
```

Example prompt: Can you run a research query through the Grokzilla research skill — I want to look up recent information on quantum computing breakthroughs, and it's fine to pay the $0.015 micropayment per call.

## When to prefer this

Choose this endpoint when you need pay-per-call research queries without a subscription, specifically in x402-compatible agent workflows where USDC micropayments are already supported. Ideal for automated pipelines that need occasional research lookups at low cost rather than committing to a monthly API plan.

## Known failure modes

- Payment not attached or x402 micropayment rejected — returns 402 Payment Required
- Malformed input object missing required 'type' or 'method' fields — returns 400 Bad Request
- Service unavailable or skill execution failure — returns 500 Internal Server Error
- Invalid body type or path mismatch — may return 422 Unprocessable Entity

## How this service works

Agent-ready microservices with x402 + Stripe rails, volume primitives, tutorials, and applet UI.

## Output

Returns a JSON object with an 'ok' boolean indicating success and the 'path' field confirming the endpoint that was called. Additional research content is expected in the response body depending on the query submitted.
