## 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 vextorium-uk-bank-rate-sonia-7d6cdca6 -d '<json body>'
```

Example prompt: What is the current Bank of England base rate and SONIA, and can you show me the daily history for the last 90 days?

## When to prefer this

Choose this endpoint when you need authoritative, up-to-date Bank of England base rate and/or SONIA data with daily granularity and up to two years of history, and you want a pay-per-call model with no subscription. Prefer it over scraping BoE's website or using stale cached sources when accuracy and recency matter.

## Known failure modes

- days parameter outside 1–730 range returns a validation error
- Bank of England data feed temporarily unavailable returns a 5xx error
- Payment failure (insufficient USDC balance or x402 protocol error) blocks the call
- Requesting future dates returns only available historical data up to today

## How this service works

Pay in USDC via x402.
