How this service works
Free float for a ticker — the share count genuinely available to trade, net of insider, strategic and restricted holdings — plus `free_float_percent` (0-100), the derived `restricted_percent`, and the `effective_date`. The correct denominator for squeeze and liquidity work: short interest as a percentage of float, not of shares outstanding. From x402stock
Output
Returns a JSON object with the ticker symbol, the absolute free float share count, free_float_percent (0-100 scale), restricted_percent (complement of float), effective_date of the data, an optional note, a source identifier ('x402stock'), and an as_of timestamp. Null values may be returned for any data field if unavailable.
Example use cases
Short squeeze ratio calculation
“I'm building a short squeeze screener. Can you pull the free float for AMC so I can compute short interest as a percentage of float rather than shares outstanding?”
Liquidity check before a large trade
“Before I place a large block order in SPCE, can you look up the free float and free float percent so I can gauge how liquid this stock really is?”
Insider lock-up analysis
“How much of RIVN's shares are restricted or held by insiders versus freely tradable? I need the restricted percent and free float figures from x402stock.”

Endpoint
GEThttps://agents.x402stock.xyz/api/v1/float/{ticker}When to prefer
Choose this endpoint when you need the precise tradable share count net of insider, strategic, and restricted holdings — especially as the denominator for short interest ratios, squeeze scoring, or liquidity analysis. Prefer this over shares-outstanding figures whenever float-adjusted metrics are required. It is specifically designed for US-listed equities and returns the effective date so you know the data vintage.
