## 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 scrapemole-pulse-ecb-fx-historical-rates-e5749581
```

Example prompt: Pull the official ECB historical exchange rates for EUR and GBP against USD from September 1 to October 9, 2026 — I need the daily series plus the min, max, and percentage change stats for each currency.

## When to prefer this

Choose this endpoint when you need official ECB reference rates over a date range rather than a single day — especially for trend analysis, reporting, or reconciliation. Prefer it over live FX APIs when regulatory or audit-grade sourcing (ECB) is required and rates are for reference, not transaction execution. Ideal when you need per-currency statistics (min/max/changePct) alongside the raw series without post-processing.

## Known failure modes

- Missing required 'start' or 'symbols' query parameters returns a 400 error
- Invalid date format (not YYYY-MM-DD) causes a parsing error
- Requesting more than 10 symbols exceeds the documented limit
- Date range with no ECB data (e.g. weekends only, or future dates) may return empty series
- Payment not settled (402) if USDC/x402 payment header is missing or insufficient
- Unknown currency codes return empty or partial rate data

## How this service works

Pay-per-call "state of the world" lookups that language models cannot know on their own: official ECB exchange rates (latest, historical, conversion), the current time and DST-aware time-zone conversion for scheduling, global weather forecasts (MET Norway, by coordinates or place name) and the live Hacker News front page. Public, non-personal data with sources and licences in every response. USDC via x402, no accounts.

Payments: x402 v2, scheme "exact", USDC on Base (eip155:8453). The payment is verified before the work and settled only when the response is 200. Terms: https://pulse.scrapemole.workers.dev/terms

## Output

A JSON object containing: the base currency, start/end dates, number of days, a chronological array of daily rate objects (date + rates per symbol), per-symbol statistics (min, max, first, last, changePct), a note about ECB publication timing, and full source attribution with URL.
