There are two price surfaces, and which one a screen may use depends on whether it is tied to one eligible investor. Market-data display carries licensing obligations that sit with whoever shows the data, so this boundary matters as much as any call.

What a price contains

Securitize returns consolidated market data: the best bid, the best offer and the last sale, each with its size and the venue it came from. Show and attribute those values; do not present a derived figure as the national best bid and offer. symbol accepts AAPL, AAPL/USD or AAPL/USDC; every answer names the asset AAPL/USD.

Real time is entitled per investor

Your one API key does not by itself entitle you to real-time data. Each real-time request names an eligible investor, and the entitlement, the limit and the record all attach to that investor:
  • A limit per investor: one request a second and sixty an hour, the same limit each trading call has. Poll on a fixed cadence tied to a visible ticket, not on every keystroke.
  • A record per request: every real-time price is recorded against the investor it was made for, with their classification.
  • Eligibility per request: the investor must be verified with a verified suitability, and in the EEA a passed DLT test.
Securitize treats each investor as a non-professional subscriber unless told otherwise; contact Securitize about an investor who is a professional. Any screen that is not tied to one eligible investor (a market list, a symbol page, a logged-out view) uses the delayed price, labelled as delayed. Before launch, Securitize’s compliance team audits how your screens show market data, the NBBO included, as part of the compliance UI audit.
