## 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 the402-ai-public-json-api-response-shape-snapshot-purchase-09efe1bf -d '<json body>'
```

Example prompt: Go ahead and purchase the Public JSON API Response Shape Snapshot service on the402.ai marketplace — I want to capture and inspect what a public JSON API endpoint actually returns so I can understand its response structure.

## When to prefer this

Choose this endpoint when you need to programmatically capture and inspect the response shape (schema) of a public JSON API, and you want to do so via a paid, on-demand marketplace service with async job tracking. Prefer this over manual inspection or free alternatives when operating within an AI agent workflow that uses x402 micropayments on the402.ai platform.

## Known failure modes

- Payment failure — insufficient USDC balance or x402 payment rejected, returning a 402 error
- Invalid or unreachable target API endpoint — job created but fails during execution
- Service unavailable — the402.ai marketplace is down or the specific service is inactive
- Malformed request body — missing required parameters returns a 4xx validation error
- Job creation succeeds but processing times out, requiring a status check to confirm failure

## How this service works

Purchase: Public JSON API Response Shape Snapshot

## Output

Returns a JSON object containing a job_id (unique identifier for the submitted job), a status string indicating the current state of the job, and a thread_id for tracking the processing thread. The job runs asynchronously so the agent should poll for completion using the job status endpoint.

## Response schema (JSON Schema)

```json
{
 "type": "object",
 "properties": {
  "job_id": {
   "type": "string"
  },
  "status": {
   "type": "string"
  },
  "thread_id": {
   "type": "string"
  }
 }
}
```
