Security Report

6.2

Moderate6.2Moderate Risk

wattprice is a small, well-scoped PVPC electricity price client that forwards a single documented query to the ESIOS API using the user's own key from ESIOS_API_KEY. The code is clean: inputs are validated against enums and an allowlist, the key is never hardcoded or logged, errors are surfaced honestly, and tests run against an injected fake fetch. Only minor observations remain, mainly that the ESIOS_API_BASE override lets the API key be sent to an arbitrary host if the environment is controlled by an attacker, and the server requires network_http and env_vars, which match its purpose. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 2 high severity). Package verification found 1 issue.

wattprice

What does electricity cost right now under Spain's regulated PVPC tariff? wattprice asks the ESIOS API — the data service run by Red Eléctrica de España — for the PVPC (Voluntary Price for the Small Consumer) indicator and returns the prices payload as JSON, for a date range and geographical area you choose.

Everything except the API key itself is optional, with the defaults the upstream documents:

locale — es (default) or en
startDate / endDate — ISO 8601 bounds; an absent range means today, start to end of day
timeAggregation — sum (default) or average
timeTruncation — hour, day, month, or year
geographicalAggregation — sum (default) or average
geographicalIds — string IDs: 3 España, 8741 Península, 8742 Canarias, 8743 Baleares, 8744 Ceuta, 8745 Melilla; defaults to the five system IDs 8741–8745
geographicalTruncation — country or electric_system

Configuration

You bring your own ESIOS API key (free registration at esios.ree.es):

export ESIOS_API_KEY="your key"

Without it, wattprice does not guess: the call fails with an error naming ESIOS_API_KEY, and no prices are invented. ESIOS_API_BASE overrides the API base URL (https://api.esios.ree.es by default).

CLI

ESIOS_API_KEY=... npx @reneturcios/wattprice prices
ESIOS_API_KEY=... npx @reneturcios/wattprice prices --locale en --time-truncation day --geographical-ids 8741
npx @reneturcios/wattprice --version

Output is the ESIOS prices payload as JSON. Exit codes: 0 on success, 1 on a runtime error (including a missing key or a non-200 upstream response), 2 on a usage error.
