Natural-language queries over a verified emissions knowledge graph, plus standards validation
Today is the operative word: we check dVeracity Semantic API every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
Endpoint below is the one we actually reach during checks — not the one copied from a README. Last verified 3 min ago.

This one needs environment variables set before it will start:
DVERACITY_API_KEY (dVeracity API key (dvrc_...). Required for the stdio package; metered calls are billed to it. Not used by the remote endpoint, which authenticates with OAuth.), DVERACITY_API_URL (Optional. Override the API base URL; defaults to production.), DVERACITY_KERI_AID (Optional. Agent AID enabling vLEI-verified identity mode.), DVERACITY_KERI_PRESENTATION (Optional. Path to the CESR presentation used with the agent AID.).
The author declared them in the registry entry; get the values from the project itself.
This endpoint answered with an authorization challenge. The server is running, and it signs you in through your browser: there is no API key to paste.
