Base URL: https://data.financialresearch.gov/hf/v1

Quick Start

import requests
import pandas as pd

BASE = "https://data.financialresearch.gov/hf/v1"

# List all available datasets
resp = requests.get(f"{BASE}/series/dataset")
datasets = resp.json()
# Returns: {"ficc": {...}, "fpf": {...}, "scoos": {...}, "tff": {...}}

# Search for series by keyword
resp = requests.get(f"{BASE}/metadata/search", params={"query": "*leverage*"})
results = resp.json()
# Each result: {mnemonic, dataset, field, value, type}

# Fetch a single time series
resp = requests.get(f"{BASE}/series/timeseries", params={
    "mnemonic": "FPF-ALLQHF_LEVERAGERATIO_GAVWMEAN",
    "start_date": "2015-01-01"
})
series = resp.json()  # [[date, value], ...]
df = pd.DataFrame(series, columns=["date", "value"])
df["date"] = pd.to_datetime(df["date"])

Authentication

None required. The API is fully open and free.

Data Categories

The HFM organizes data into six categories (each downloadable as CSV):

• size — Hedge fund industry size (AUM, count of funds, net/gross assets)
• leverage — Leverage ratios, borrowing, gross notional exposure
• counterparties — Counterparty concentration, prime broker lending
• liquidity — Financing maturity, investor redemption terms, portfolio liquidity
• complexity — Open positions, strategy distribution, asset class exposure
• risk_management — Stress test results (CDS, equity, rates, FX scenarios)
