Fund Letters

List investor letters from hedge funds, partnerships, and registered funds, filterable by manager, fund, company, period, source, and distribution tier.

Retrieve one letter with letter-level narratives, performance figures, and inline theses (capped at 25; thesisCount carries the total). Superseded/merged IDs resolve forever via aliases.

Retrieve the original letter document (format=pdf, 302 redirect) or page-segmented markdown whose bytes verify every anchor (format=markdown).

Keyset-paginated delta feed of fund-letter events (letter.published, letter.updated, letter.superseded, thesis.extracted, manager.added). Never response-cached.

Company coverage index: every company with at least one extracted thesis, with thesis/manager/letter counts and the latest stance.

List funds that publish letters, with per-fund letter counts.

Retrieve one fund. Merged fund IDs resolve forever via aliases; the response carries the canonical id plus requestedId when they differ.

List letter-publishing managers (firms) with coverage stats: letters, funds, companies, theses, period range, and cadence.

Retrieve one manager profile. Merged manager IDs resolve forever via aliases; the response carries the canonical id plus requestedId when they differ.

Fund Overview: one token-efficient briefing per manager — canonical name, description, founders, website, coverage counts, and the latest letter’s highlights with up to 5 headline theses.

Full-text search over letter bodies; hits carry page-anchored highlights.

Semantic (vector) search over letter content; hits carry similarity scores, matched chunks, and page anchors.

Cross-cutting thesis screen: structured per-company extractions (relationship, stance, conviction, narratives, verbatim anchored quotes) across all letters.
