The signals quants actually use, not another OHLCV proxy.
Most retail finance APIs reshuffle the same price feed. HedgeFriend is built around the alternative data that academic literature has repeatedly shown to be predictive — and that public agencies already publish for free.
Primary sources only
SEC EDGAR, CFTC, FEMA, FRED, the Federal Register, state WARN registries. We don't scrape — we pull from the agency.
One auth, one shape
A single bearer token. Consistent JSON envelopes. Predictable pagination. No SOAP, no XBRL parsing on your side.
Indie-friendly pricing
Plans starting at $0/mo. Signups are currently paused as we scale our infrastructure.
24 feeds. One key.
SEC Filings
10-K, 10-Q, 8-K and other filings — type, date, period of report, and direct document URL.
Insider Trades
Form 4 transactions: who at the company bought or sold, share count, price, transaction code.
Institutional Holdings
13-F filings: fund name, position size, market value, period.
Reg-A+ Offerings
Form 1-A and amendments — issuer, CIK, offering amount, primary document URL.
XBRL Financials
As-reported Revenue, NetIncome, EPS, TotalAssets and more from structured 10-K/10-Q filings.
CEO Compensation
Named executive officer pay from proxy statements: salary, bonus, stock awards, option awards, and total compensation.
CFTC Commitments of Traders
Long/short positioning by trader category — commercial, non-commercial, open interest — for tracked futures contracts.
FEMA Disaster Declarations
Federally declared hurricanes, floods, wildfires, severe storms by event type, state, and date.
Wikipedia Attention
Daily pageview counts for the company's Wikipedia article — raw counts, no smoothing.
JSON that behaves the same on every endpoint.
Every list endpoint returns the same envelope: a data array, a meta block with pagination, and an X-RateLimit-* header on every response. Errors come back as { error, code }. That's it.
- Bearer token auth — no signing, no OAuth dance.
- ISO-8601 dates. UTC always. Decimal numbers as numbers.
- Rate limits surfaced via headers. No quota guessing.
