Every source StatCite serves, and every source it evaluated and refused, with the licence verdict, the basis for it, and the date it was last checked against the source's own terms. A source enters the indicator registry only after its ledger entry exists with a "served" verdict. This page renders live from /v1/sources, so it cannot drift from what the API actually reports.
served StatCite serves this source's data under the stated licence, and every response carries the required attribution. flow_through an aggregator, so each served series inherits its underlying provider's licence, and the citation names that provider. refused evaluated and deliberately not served. The entry says exactly why. Declining a source for licensing reasons is product information, not an internal detail.

~1,400 annual indicators, 200+ economies, many from 1960
Licence: Published IMF statistical data may be copied, redistributed, and used (including in derivative works) with attribution to the IMF as source. Conditions: attribute as "Source: International Monetary Fund, <database>, <link>"; do not alter the data in ways affecting its accuracy, and state explicitly if it is materially transformed; anyone redistributing it downstream must take reasonable efforts to communicate these terms to their own users; and if sold as a standalone product, purchasers must be told the data is available free of charge from the IMF. Some statistical products incorporate third-party information under separate terms
The IMF's SPECIAL TERMS for published statistical data (effective 2024-10-11) expressly permit copying, redistribution, derivative works and use with attribution. They form a separate regime, more permissive than the general IMF Content terms, and open with "Notwithstanding the general prohibition on the commercial use of IMF Content...". Named datasets include the WEO database, IFS, BOP, DOT, GFS, Primary Commodity Prices and data on the iData Portal. StatCite must attribute data in the IMF's format (database and link). It must never alter data in ways affecting accuracy, and must declare any material transformation. It must communicate these terms downstream to its own users, which it does through this ledger, /v1/sources and the licence field on every citation. Where data is sold as a standalone product, it must tell purchasers the data is free from the IMF, which the Apify actor listing does. Corrected 2026-08-10: the previous note claimed commercial reuse 'may require IMF permission', which conflated the Content regime with the Data regime and both understated the permission and overstated the restriction.
Growth, fiscal and external indicators for 190+ economies, including estimates and projections, in twice-yearly vintages (April and October, plus interim Updates). The primary path is the IMF's own DataMapper API, which serves the current edition and passes its edition label through verbatim. If that path is unavailable, StatCite falls back to the newest edition DBnomics has ingested, which can lag the IMF's release calendar. Every response cites the resolved vintage, and a fallback that crosses editions is disclosed (verify_stat demotes such cases to cannot_verify rather than judging a claim against a superseded vintage). The actual/projection boundary is a heuristic derived from each response's own data horizon, not a per-country authoritative cutoff

This source is governed by the same IMF special terms for statistical data as imf_weo. The WEO database is named in them explicitly, and the delivery endpoint does not change the licence on the data. The api.imf.org service itself imposes no additional terms on anonymous use: the API-management terms sit behind the portal sign-in and govern subscription keys, which StatCite does not hold and does not need. This was verified by a direct anonymous call on 2026-08-10.
Frozen dated WEO editions published as first-party SDMX 3.0 dataflows. StatCite uses them ONLY on the dated-vintage path (as_of verification and the revision probe), never in the live chain, and only for editions enumerated in IMF_VINTAGE_FLOWS from the live dataflow listing. The IMF exposes a small number of recent vintages, not an archive. DBnomics remains the deep historical fallback back to 2010-04, so this source narrows the newest-edition gap rather than replacing the aggregator
Licence: Published for information purposes; reuse with attribution; not transaction rates
ECB disclaimer permits reproduction with source attribution; the reference rates are explicitly informational, and StatCite labels them as reference (not transaction) rates.
~30 major currencies, daily since 1999
Licence: BIS statistics may be reproduced and redistributed with attribution; see the BIS terms and conditions for statistics
The BIS terms for statistics permit reproduction and redistribution with attribution to the BIS. StatCite charges for the audit/convenience layer, never for BIS data standalone, and attributes the BIS on every response.
Policy rates for 49 economies (the rate that best captures each monetary authority's policy stance), monthly and daily, via the BIS SDMX API
Licence: ECB content may be reproduced with attribution; see the ECB disclaimer and copyright notice
The ECB's copyright notice permits reproduction of its published content with attribution to the ECB as source. This entry is distinct from ecb_fx, which covers the euro reference exchange rates served via Frankfurter.
Euro-area harmonised inflation (HICP) and related monetary series via the ECB Data Portal SDMX API
Licence: ECCB website terms of use, plus written permission granted to the operator
The ECCB's published website terms grant use of the site for personal, non-commercial purposes and reserve reproduction and redistribution unless permission is given. The operator wrote to the ECCB describing exactly this service, including scheduled fetching, storage, and serving each value with attribution and a link back to the source table, and permission was granted. This entry was recorded on the operator's confirmation of 2026-08-14. The correspondence itself is held privately rather than published, so the entry states its basis rather than quoting it. The request that was granted is public at github.com/asokore/statcite in caribstat/outreach/.
ECCU monetary, fiscal, debt, tourism, interest-rate and CPI statistics for the eight ECCB member geographies and the currency union aggregate, annual, quarterly and monthly. It includes Anguilla and Montserrat, which are not World Bank reporting economies and appear in few other machine-readable sources. The figures are collected on a schedule from the ECCB's published tables and served with the bank's own data-as-at stamp, carried separately from our retrieval time.
Licence: Central Bank of Barbados website terms of use, plus written permission granted to the operator
The Bank's published website terms reserve reproduction and redistribution of site content unless permission is given, and the operator requested and obtained that permission. This entry was recorded on the operator's confirmation of 2026-08-14. The request that was granted is public at github.com/asokore/statcite in caribstat/outreach/. The Bank publishes no currency stamp, so citations name the source publication and its date rather than asserting how current the Bank considers a figure.
Barbados balance of payments back to 1967, GDP, inflation and retail prices, tourism, and the monetary survey, from the Bank's published workbooks. The Bank prints no "data as at" stamp, so every value instead names the publication it came from and links that workbook directly, which is a narrower claim than a currency stamp and one a reader can check.
Licence: Per underlying provider
Aggregator: each served series inherits its underlying provider's licence, and the citation object names that provider. The CURATED registry routes only IMF series through DBnomics. The raw get_series escape hatch (dbnomics/PROVIDER/... ids) passes any DBnomics-hosted provider through on flow-through terms: the citation names the provider and states that its terms apply, and StatCite has NOT individually verified every provider's licence. Consumers of non-IMF dbnomics/ series must check the named provider's own terms before republishing. Corrected 2026-08-10: the previous note claimed only permitted providers were routed, which was true of the registry but overstated the raw-id path.
Tens of millions of series from 90+ official providers (IMF, OECD, Eurostat, ECB, BIS, national statistical offices)
Licence: FRED Services Terms of Use, clauses (p) and (q), see https://fred.stlouisfed.org/legal/
Clauses (p) and (q) of the FRED Services Terms of Use reserve FRED content from AI/ML/LLM-connected use and from storing, caching or archiving it. StatCite does not offer FRED, with or without an operator key: the six US-only registry keys and the fred/ series id are recognised and always decline, naming the reason.
Not served. The FRED Services Terms of Use, clauses (p) and (q), reserve FRED content from use in connection with training or running AI/ML/LLM systems, and from storing, caching or archiving it.
Licence: UN Comtrade policy on use and re-dissemination
The policy states "To re-disseminate UN Comtrade data, a user must be an active premium subscriber" and prices "for-profit data extraction and/or streaming application[s]" under a licensing fee. StatCite offers a metered surface on Apify, which places it within that fee-bearing category.
Not served. UN Comtrade's policy on use and re-dissemination requires an active premium subscription to re-disseminate its data, and licenses for-profit extraction or streaming applications for a fee.
Licence positions are re-verified when sources are added or terms change. Each entry carries its own verified-on date. If you believe a verdict is wrong, or a refused source's terms have changed, email hello@statcite.com. Corrections are welcome and acted on.
