Of 20 free price sources, only 2 clearly permit commercial display — 9 are research-only and must never reach paying users

Asked (summary):

Which free price sources exist by market, what are their terms for commercial display, rate limits, and update frequency — and which are research only and must never be shown to paying users?

A curated licensing-screening matrix of 20 free source/product rows across 16 independent hosts, spanning FX, crypto, equities, bonds, macro, energy and commodities. Each row is screened conservatively: only terms that explicitly permit commercial external display count as ALLOWED; personal, non-commercial, internal or non-display tiers are RESEARCH ONLY; everything else is VERIFY / LICENSE until rights are documented. Free API access by itself grants no display or redistribution rights, and exchange or third-party entitlements can override a provider plan. This is a screening matrix, not legal advice.

Allowed — terms explicitly permit commercial external display Verify / license — rights unstated or conditional; keep off until documented Research only — personal / non-commercial / non-display tier

Operational terms: rate limits and update frequency

Null fields are shown as "not stated" — a missing limit is never "unlimited". Source names link to the terms page each row was screened from.

Method: curated display-rights screening matrix of 20 free source/product rows across 16 independent hosts (no URL supports more than 5% of rows), compiled from each provider's published pricing, terms or license pages; the World Bank row reflects the current Commodity Markets Outlook (October 2026, CC BY 3.0 IGO) rather than the dated 2020 edition. Policy measures whether exact free-tier terms explicitly permit commercial external display to paying users; nulls are kept as "not stated". Long terms, attribution and caveat text abridged for space; full text at the linked pages. Not legal advice.
