What is the WhaleWisdom API?

The WhaleWisdom API exposes 3 endpoints covering SEC 13F institutional filing data, including filer search, paginated latest filings, and current quarter statistics. The get_latest_filings endpoint returns structured filing records with fields like filer_name, period_of_report, form_type, and state, letting developers query the most recently imported 13F reports ordered by import date.

Typed, relational, agent-ready

A generated client with real types, enums, and the links between objects — the structure a flat JSON response can't carry. Autocompletes in your editor and reads cleanly to coding agents.

About the WhaleWisdom API

Endpoints and Data Coverage

The API covers three core areas of WhaleWisdom's 13F dataset. get_latest_filings returns a paginated list of the most recently imported 13F reports. Each filing object includes filer_name, filer_permalink, period_of_report, filed_as_of_date, date_imported, form_type, state, sto, and total_records for the full result set. The rows parameter accepts values between 1 and 100, and the page parameter enables stepping through large result sets.

Filer Search

search_filers accepts a term string and returns matching filers and stocks by name — useful for autocomplete-style lookups when you know part of a firm's name, such as 'Berkshire' or 'Bridgewater'. Each result includes id, name, permalink, and type (either filer or stock), making it straightforward to resolve a human-readable name to a stable identifier for further queries.

Quarter Statistics

get_filing_quarter_stats takes no inputs and returns metadata about the current 13F filing quarter: quarter_description, due_date (in YYYY-MM-DD format), filings_count (total filings imported so far this quarter), and new_filers — an array of first-time filers with their id, name, and permalink. This is useful for monitoring filing season progress and identifying newly registered institutional filers.

Reliability & maintenanceVerified

The WhaleWisdom API is a managed, monitored endpoint for whalewisdom.com — not a raw scraper you maintain. Every endpoint is automatically health-checked on a schedule, and when whalewisdom.com changes and a check fails, the API is automatically queued for repair and re-verified. It is built to keep working as the site underneath it changes.

This isn't an official whalewisdom.com API — it's an independent, maintained REST wrapper over public data. Where the source has no official API (or only a limited one), Parse gives you a stable contract over a source that never promised one, and keeps it current. Need a new endpoint or field? You can revise it yourself in plain English and the agent rebuilds it against the live site in minutes — contributing the change back to the shared API is free.

Maintenance
Monitored & self-healing
Will this API break when the source site changes?+
It's built not to. Every endpoint is health-checked on a schedule with automated test probes. When the source site changes and a check fails, the API is automatically queued for repair and re-verified — that's the self-healing layer. Each API page shows when its endpoints were last verified. And because marketplace APIs are shared, any fix reaches everyone using it.
Is this an official API from the source site?+
No — Parse APIs are independent, managed REST wrappers over publicly available data. That is the point: where a site has no official API (or only a limited one), Parse gives you a maintained, monitored endpoint for that data and keeps it working as the site changes — so you get a stable contract over a source that never promised one.
Can I fix or extend this API myself if I need a new endpoint or field?+
Yes — and you don't have to wait on us. This API was generated by the Parse agent, which stays attached. Describe the change in plain English ("add an endpoint that returns reviews", "fix the price field") in the revise box on the API page or via the revise_api MCP tool, and the agent rebuilds it against the live site in minutes. Contributing the change back to the public API is free.
What happens if I call an endpoint that has an issue?+
Errors are machine-readable: a bad call returns a clean status with the list of available endpoints and a repair hint, so an agent (or you) can recover or trigger a fix instead of failing silently. Confirmed failures feed the automatic repair queue.
Common use cases
  • Displaying a live feed of the most recently filed 13F reports with filer name and period of report
  • Building an autocomplete input to look up hedge funds or institutional filers by partial name
  • Tracking how many 13F filings have been imported in the current quarter using filings_count
  • Identifying first-time 13F filers each quarter via the new_filers array from get_filing_quarter_stats
  • Mapping filer_permalink values to profile pages for institutional investors
  • Monitoring the 13F filing deadline date for the current quarter via due_date
  • Filtering recently imported filings by form type or state using data from get_latest_filings

Frequently asked questions
Does WhaleWisdom have an official developer API?+
WhaleWisdom offers paid data subscription plans at whalewisdom.com but does not publish a documented public REST API for third-party developers. This Parse API provides structured access to the same 13F filing data.
What does `get_latest_filings` return beyond the filer name?+
Each filing object includes filer_permalink, period_of_report, filed_as_of_date, date_imported, form_type, state, and sto (number of stocks in the filing), along with a total_records count for the full result set. Pagination is controlled with the page and rows parameters.
Does the API return the individual stock holdings within a specific 13F filing?+
Not currently. The three endpoints cover filing-level metadata, filer search, and quarter statistics. Individual position-level holdings data (specific stocks, share counts, market values) per filing is not exposed. You can fork this API on Parse and revise it to add an endpoint returning holding details for a given filer and period.
How fresh is the data returned by `get_latest_filings`?+
The endpoint returns filings ordered by date_imported descending, reflecting the order in which WhaleWisdom processed them. The filed_as_of_date and date_imported fields on each record let you assess both when the filer submitted to the SEC and when it appeared in the dataset.
Can I retrieve historical 13F filings for a specific filer across multiple quarters?+
Not currently. get_latest_filings returns recently imported filings across all filers, and search_filers resolves names to identifiers but does not return historical filing history. You can fork this API on Parse and revise it to add a per-filer historical filings endpoint using the permalink values already returned by search.
