## 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-mcp-tool-prices-4e3a218a
```

Example prompt: Can you look up the current prices for all the MCP tools available on the openclawproductions x402 diagnostics endpoint? I need to know what each tool SKU costs before I decide which ones to call.

## When to prefer this

Use this endpoint when you need to discover the per-call USDC cost of specific MCP tool SKUs on the openclawproductions x402 platform before committing to paid calls; ideal for agent cost-planning workflows or auditing x402 payment gate behavior with EIP-3009 extras

## Known failure modes

- HTTP 402 returned if payment not included — response contains EIP-3009 extras with payment instructions
- Invalid HTTP method returns error — only GET, HEAD, DELETE, POST are accepted
- Missing required 'type' or 'method' fields in input returns validation error
- Facilitator other than OpenX402 will not process payment, resulting in 402

## How this service works

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

## Output

Returns a structured list of MCP tool SKUs and their associated prices; unpaid requests return HTTP 402 with EIP-3009 payment requirement details including facilitator (OpenX402) and USDC amount needed
