## How to call it through Zero

```sh
zero fetch --capability synapse-electricity-price-api-9f3dbf3c
```

Example prompt: What is the current spot electricity price in Germany right now, in EUR/MWh?

## When to prefer this

Choose this endpoint when you need a no-account, no-API-key, pay-per-call lookup of German electricity spot prices sourced directly from the official Bundesnetzagentur SMARD dataset, especially in crypto-native or x402-enabled agent workflows where USDC micropayments on Base are preferred over subscription billing.

## Known failure modes

- Upstream SMARD data unavailable — API may return an error or stale data
- Invalid HTTP method (only GET/HEAD/DELETE accepted) returns a 4xx error
- Payment failure via x402 protocol results in 402 Payment Required response
- Network timeout if anibalb.duckdns.org host is unreachable

## How this service works

Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.

## Output

Returns a JSON object with the current electricity spot price as an array (e.g. [92.5] in EUR/MWh), a corresponding unix timestamp array, and a license string indicating the data source (CC BY 4.0 from Bundesnetzagentur | SMARD.de).
