Tools
| Tool | Description | Behaviour |
|---|---|---|
| catalog_info | Return the catalog's notice, schemaVersion, generated time, entry count and the download URLs of the full catalog as JSON and CSV. | Read-only |
| compare_entries | Place the catalog's fields for up to 5 entries side by side. Values are the catalog's own; a field the catalog does not have shows Not in catalog. | Read-only |
| export_catalog | Export the Signal Lab catalog as JSON or CSV: every entry, or only those matching the same filters as search_catalog (no result cap). Optional fields picks columns by catalog field name. CSV has a header row, joins lists with "; " and repeats the catalog notice in the last column. Also returns the static download URLs. | Read-only |
| get_entry | Return one catalog entry by slug, with every field the catalog has for it (limits, coverage, auth, license, licenseNote, source URLs, lastVerified). Get slugs from search_catalog. | Read-only |
| get_source_urls | Return where each entry's data comes from: the provider's site, docs and evidence pages, the license or terms URL with the license note, and the lastVerified date, plus the Signal Lab page. Pass up to 25 slugs, or the same filters as search_catalog (all entries if none). A URL the catalog does not record is left out. | Read-only |
| list_filters | List the values the catalog uses for type, badge, auth, category, license, task, verified and lastVerified, with how many entries have each. Call this first to pick exact filter values. | Read-only |
| search_catalog | Find free and free-to-start financial data sources, tools and models in the Signal Lab catalog by text and by filters (category, type, access badge, sign-up needed, license, task, verified, verified_since; see list_filters for the values). Returns up to 25 summary rows in name order, each with lastVerified and sitePageUrl. Use get_entry for every field of one entry, export_catalog for the whole list, get_source_urls for provider and terms links. | Read-only |
