## Steps

1. Open the RapidAPI listing and subscribe to the Basic or paid plan.
2. Use the RapidAPI-generated request headers only; do not use private direct-server headers.
3. Open POST /tasks/proof-audit in the RapidAPI playground or your buyer-agent HTTP client.
4. Send the workflow name, buyer-agent intent, seller-agent role, target network, desired price, and step evidence.
5. Review audit_score, blocking_gates, warnings, marketplace_fit, and revenue_claim before spending or delegating.
6. Buy the fixed-scope audit only when a human-reviewed proof report is needed.

## Sample Payload

```json
{
  "workflow_name": "Agent marketplace seller proof",

  "seller_agent_role": "proof and reliability auditor",
  "target_network": "rapidapi_agent_api_marketplace",
  "desired_price_usd": "0.25",
  "steps": [
    {
      "name": "Accept buyer-agent request",
      "actor": "buyer agent",
      "input": "workflow evidence, price, and intended marketplace",
      "output": "request accepted through RapidAPI",
      "failure_mode": "missing proof or invalid marketplace billing path",
      "evidence": "RapidAPI request log"
    },
    {
      "name": "Return proof decision",
      "actor": "seller proof agent",
      "input": "workflow steps and receipts",

    }
  ]
}
```

## Expected Response Fields

- `audit_score`: 0-100 proof-readiness score.
- `blocking_gates`: Fix these before claiming a workflow is ready to sell or delegate.
- `warnings`: Non-blocking risks to disclose or improve.
- `marketplace_fit`: Fit assessment for the named agentic marketplace route.
- `revenue_claim`: False unless a real settled receipt exists.

## Pricing

- RapidAPI: 0.25 USD per request
- Free quota: 3 BASIC requests where RapidAPI plan controls expose it
- Fixed-scope audit: 500.00 USD via Stripe-hosted checkout

## Security And Cost Policy

- Use RapidAPI-generated headers only.
- Private direct-server credentials are not public buyer instructions.
- Current route uses no OpenAI calls.
- Future OpenAI-backed variants require buyer-supplied OpenAI keys unless seller pricing is at least 3x estimated OpenAI call cost.

## Publication Boundary

This packet is ready for public buyer discovery and future RapidAPI tutorial paste-in. It is not a claim that a new live RapidAPI tutorial was created.

## Revenue Boundary

Revenue remains USD 0.00 until a real paid usage, settlement, payout, or marketplace receipt exists.
