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 chainquery-getdeploymentinfo-633812ed
```

Example prompt: What's the current soft-fork deployment and activation status on Bitcoin mainnet — are there any pending or recently activated upgrades like Taproot?

## When to prefer this

Choose this endpoint when you need Bitcoin soft-fork deployment status from an independent full node without setting up your own Bitcoin Core instance or managing API keys. Ideal for agents that need to verify soft-fork activation states on demand and are comfortable with micro-payment (x402) per-call billing. Prefer over self-hosted RPC when avoiding infrastructure overhead.

## Known failure modes

- Invalid or malformed params JSON returns an RPC error
- Payment not completed results in HTTP 402 response
- Node temporarily unavailable returns a 5xx error
- Unsupported HTTP method returns 405
- Rate limiting may apply if payment flow is not completed properly
