Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 quantaflow-x402-api-gateway-github-tool-route-67a861db -d '<json body>'
```

Example prompt: Use QuantaFlow to forward a POST request to the GitHub tool at path '/data/defi-rates' with body '{"token":"ETH"}', paying $0.01 USDC via x402.

## When to prefer this

Choose this endpoint when you need pay-per-call access to a GitHub-hosted web3 or DeFi tool via the x402 micropayment protocol and want automatic USDC billing at $0.01 per request. Prefer it over direct API calls when the upstream tool is gated behind x402 and you need transparent passthrough of request and response without additional transformation.

## Known failure modes

- Payment failure: insufficient USDC balance causes x402 payment rejection and no upstream call is made
- Invalid path: upstream returns 404 if the path below the GitHub origin does not exist
- Malformed body: upstream rejects badly formatted JSON body with a 4xx error
- Gateway timeout: Vercel cold start or upstream latency causes timeout
- Unauthorized upstream: GitHub-hosted tool returns 401/403 if additional auth is required beyond the x402 payment

## How this service works

Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.

## Output

The raw upstream response body and content type from the GitHub-hosted tool, passed through transparently after successful x402 micropayment verification. The agent receives whatever the upstream API returns — JSON data, status, or error — without additional transformation.
