## 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-rapid-threads-public-data-317fbb15 -d '<json body>'
```

Example prompt: Pull the latest public thread posts from the Rapid Threads API — use the path '/threads/latest' with a GET method and no extra query params.

## When to prefer this

Choose this endpoint when you need pay-per-call access to Rapid Threads public data without a recurring API subscription, and your agent supports the x402 micropayment protocol with a USDC wallet. It is ideal for low-frequency or on-demand thread data retrieval where per-request billing at $0.01 USDC is more economical than a flat subscription.

## Known failure modes

- Insufficient USDC balance causes payment failure and request rejection
- Invalid or malformed path results in upstream 404 or error response
- Upstream Rapid Threads API downtime returns an error passthrough
- Malformed query object or body causes upstream 400 bad request
- x402 payment protocol handshake failure if wallet not configured correctly

## 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 from the Rapid Threads public data API, passed through with its original content-type after successful x402 micropayment verification. The agent receives whatever JSON or text the upstream API returns for the requested path and query.
