## 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 fiatdock-codex-public-endpoint-snapshot-d72dceff
```

Example prompt: Call the Codex Public Endpoint Snapshot on FiatDock using a tools/call JSON-RPC 2.0 POST and retrieve the latest snapshot data — I want the result forwarded exactly as-is from the seller's MCP server.

## When to prefer this

Choose this endpoint when you need to invoke a specific Codex-branded MCP tool via a pay-per-call micropayment model without setting up your own MCP infrastructure; ideal for agents that need on-demand, low-cost access to Codex snapshot data with x402 payment protocol support.

## Known failure modes

- Missing required tool arguments returns an argument error (counted as a settled call, $0.005 charged)
- Malformed JSON-RPC body causes forwarding failure
- Seller's MCP server unavailable returns a connectivity error
- Incorrect jsonrpc version string causes rejection
- Unknown method name returns a JSON-RPC method-not-found error

## How this service works
