Notice: Information presented for educational purposes only. Free tiers, limits, and licenses belong to the providers and may change. Users must verify and follow each provider's terms.

Start with type=Dataset (the "Datasets" section below, 29 entries); read license and licenseNote before using data in a product.
Many free tiers are for personal or internal use, and terms differ by provider. If you are building a trading bot or another product, read each provider's own terms and the license and licenseNote fields before relying on an entry.

Field meanings (names as in catalog.json). In the entries below: License shows license and licenseNote together, Free Tier is freeTierLimits, Rate Limits is rateLimits, Page is sitePageUrl, Provider is providerUrl.
- type: Kind of entry. Values in the catalog: "Dataset", "Tool", "Model", "Recipe", "Starter Kit".
- badge: Values in the catalog: "Free", "Open Source", "Freemium", "Unofficial". The homepage counts Free and Open Source as "fully free or open source" and Freemium and Unofficial as "with a free tier or unofficial access".
- auth: Authentication requirement. Values in the catalog: "none", "free API key", "account", "none (v1); free registration key for v2", "free account; API key issued from the dashboard", "free registration key for the API; none for bulk files".
- rateLimits: API rate limits (if available)
- freeTierLimits: Free tier usage limits (if available)
- license: Shows where the terms live: "Provider terms" is the provider's own terms of service, "Custom" is a license or notice specific to that provider, "unknown" marks Signal Lab originals whose reuse terms are not yet published, other values name a license. It is not a permission to use the data; read licenseNote and the linked terms. Values in the catalog: "Custom", "Provider terms", "unknown", "Apache-2.0", "MIT", "BSD-3-Clause", "CC0-1.0", "GPL-3.0-or-later", "CC-BY-NC-SA-4.0", "BSD-2-Clause".
- licenseNote: Entry-specific wording about the terms. Read it together with license and the linked terms before using data in a product
- tasks: Task tags for the entry; the /browse page filters on them
- lastVerified: Date (YYYY-MM-DD) we last compared the entry with the provider's pages
- coverage: What a dataset covers (instruments, sources, history, delays), as free text recorded for the entry. Only Dataset entries have it. Recorded on 29 of 84 entries.
- attribution: The attribution wording or rule recorded for the entry, as the provider states it (for example a credit line to display). Missing means not recorded, not that none is required. Recorded on 12 of 84 entries.
- evidenceUrl: One provider page recorded as evidence for the entry (for example a terms, pricing or license page). Missing means not recorded. Recorded on 12 of 84 entries.
- evidenceUrls: A list of provider pages recorded as evidence for the entry; a note may cite a page not in the list. Missing means not recorded. Recorded on 70 of 84 entries.
A field that is missing has no recorded value in the catalog. It does not mean the provider has no limit, no attribution rule or no terms.
