## How to call it through Zero

```sh
zero fetch --capability x402pulse-pro-pass-purchase-71cb94ec
```

Example prompt: I want to buy a 30-day x402Pulse Pro pass — go ahead and pay the $13 USDC and get me the API key so I can start hitting all their endpoints.

## When to prefer this

Choose this endpoint when you need sustained, high-volume access to multiple x402Pulse data endpoints (Polymarket, FDA, EIA, CMS) and want a single credential rather than paying per-call. Also prefer this when setting up an MCP server integration with Claude Code, Cursor, or Claude Desktop that requires a persistent API key.

## Known failure modes

- Payment of $13 USDC not completed — key not issued
- Invalid or expired key passed to ?renew= — renewal fails
- Rate limit exceeded (120/min or 20,000/day) after key issuance
- Key displayed only once — if lost, a new pass must be purchased
- Network or payment processing error during x402 transaction

## How this service works

x402Pulse Pro: a 30-day pass for $13 USDC that returns an API key for unlimited calls (fair use: 120 a minute, 20,000 a day) to every x402Pulse endpoint, plus an MCP server for Claude Code, Cursor and Claude Desktop. Pass ?renew=<key> to extend a key. The key is shown once.

## Output

Returns a one-time-display API key valid for 30 days, granting access to all x402Pulse endpoints at up to 120 requests/minute and 20,000 requests/day, plus credentials or configuration for an MCP server compatible with Claude Code, Cursor, and Claude Desktop.
