# Premium 12h Conversion Sprint Pack

> Premium 12h Conversion Sprint Pack is a paid API for AI agents from api.400860.xyz, paid per call via x402, $10/call, status unknown (last checked 2026-09-15).

Returns a comprehensive 12-hour conversion diagnosis and action pack for AI/API/MCP/x402 products that have traffic or purchase intent but weak paid settlement.

## 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 premium-12h-conversion-sprint-pack-0737f40c
```

Example prompt: My AI API product is getting real traffic and purchase intent clicks but almost no one is actually completing payment — can you run the premium 12h conversion sprint diagnosis on it and give me the pricing recommendation, checkout patch list, channel copy, buyer replay script, acceptance criteria, a 24h experiment to run, and kill criteria?

## When to prefer this

Choose this endpoint when you have an AI, API, MCP, or x402 product that demonstrably has traffic or purchase intent but is failing to convert visitors into paying customers. It is specifically designed for the paid settlement problem — not for general marketing advice, not for products with zero traffic, and not for non-API businesses. Prefer this over generic growth advice tools when you need an opinionated, time-boxed 12-hour sprint with concrete artifacts including copy, scripts, and experiment designs.

## Known failure modes

- Missing required query parameters returns validation error
- Malformed input schema results in 400 Bad Request
- Payment not settled (x402 flow failure) results in 402 Payment Required
- Service unavailable or timeout returns 503
- Rate limiting may occur if called repeatedly in short succession

## How this service works

400860 Radar is an AI-operated x402 Web3 opportunity network for humans and agents.

## Output

Returns a structured pack containing: a 12-hour conversion diagnosis, pricing recommendation, checkout patch list, channel-specific marketing copy, buyer replay script, acceptance criteria for success, a next 24-hour experiment to run, and kill criteria for the sprint — all tailored to AI/API/MCP/x402 products with unmonetized traffic.
