List allowlisted EEA climate databases and available versions.

List version and revision aliases for an allowlisted database.

List tables in a database version.

Preview a small bounded set of rows with provenance.

List bounded distinct values after validating the column against metadata.

Find IPCC inventory sector codes by code prefix or name substring.

Returns sector_code, name, hierarchy level, and parent for each match, e.g. query 'transport' -> 1.A.3 and its subsectors.

Describe one IPCC sector code: name, level, parent, direct children.

Parents already include children; never sum a sector with its parent or children (double counting).

Curated national GHG inventory time series with the statistically correct variable.

country: ISO-style Discodata country code, e.g. 'HU', 'AT', 'EUA'. sector: 'total' or an IPCC sector code at any depth: '1', '1.A', '1.A.3' (discover codes via search_emission_sectors). Never sum a sector with its parent or children. accounting_scope: 'with_lulucf' or 'without_lulucf' (totals only). Avoids TREND/BASE_YEAR_AVG/PREV_SUBMISSION variants; sorted client-side by year.

Search the Policies and Measures catalogue (descriptive, not a ranking source).

country: PaMs country label, e.g. 'Hungary', 'Germany'. status: e.g. 'Implemented', 'Planned', 'Adopted', 'Expired'. sector/instrument_type/ responsible_entity/free_text are substring matches. Quantified effect fields are sparse; missing values mean not reported, not zero.

Fetch one policy or measure with explicit quantification semantics.

Returns the full record plus a quantification block: status is 'reported' or 'not_reported'; ex-ante values by scope (total/esr/ eu_ets/lulucf) and target year, ex-post average if reported.

Return the documented and live-tested Discodata SQL capability matrix.

Parse and validate one allowlisted, read-only, bounded SELECT query.

Explain referenced objects, joins, filters, aggregations, and query risks.

Execute a locally validated and bounded SELECT, returning rows and provenance.

Preview provenance classification for a query without executing it.

Explain reported actual, projection, policy estimate, and derived statuses.
