> x402-tools Tape Regime Diagnostic Endpoint is a paid API for AI agents from openclawproductions.com, paid per call via x402, $0.04/call, status unknown (last checked 2026-10-02).

## 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 x402-tools-tape-regime-diagnostic-endpoint-fc035e19
```

Example prompt: Run the taperegime x402 diagnostic — I want to verify the paid SKU flow is working, including that unpaid requests get a proper HTTP 402 with EIP-3009 extras and that a successful payment returns the expected JSON payload.

## When to prefer this

Choose this endpoint when you need to test or validate the x402 micropayment protocol flow end-to-end, specifically with EIP-3009 token transfer authorization and the OpenX402 facilitator. It is ideal for developers building or debugging x402-enabled APIs who want a live, low-cost ($0.04 USDC) reference implementation to probe against.

## Known failure modes

- HTTP 402 returned when no valid x402 payment authorization is provided — includes EIP-3009 extras with payment challenge
- Invalid or expired EIP-3009 signature causes payment rejection
- Facilitator not recognized if a non-OpenX402 facilitator is used
- Malformed properties parameter may result in unexpected behavior
- Network or server errors returning 5xx

## How this service works

Paid x402 diagnostics. Unpaid paid-SKU requests return HTTP 402 with eip3009 extras. Facilitator: OpenX402 only.

## Output

On successful payment: a JSON object containing the SKU name ('taperegime'), a human-readable title ('Tape Regime'), a diagnostic note, and the price ('$0.04'). On unpaid request: HTTP 402 with EIP-3009 payment challenge extras indicating required payment details.
