Terms of Use
People keep emailing to ask whether they're allowed to use biquote in their project. The answer is almost always yes — this page is that answer, in writing, so you don't have to wait for a reply. Last updated 2 September 2026.
What you may do
All of the following is permitted, for both commercial and non-commercial projects, at no cost and with no key or signup:
- Use the data in your product. Desktop apps, web apps, dashboards, bots, research pipelines — anything where biquote data is an input to what you build.
- Store it. Save quotes and OHLC bars in your own database, keep raw immutable archives, retain them forever. There is no retention limit and nothing to delete if you stop using the service.
- Display it. Show current and historical prices to your users, including paying and authenticated users.
- Build on it. Signals, charts, analytics, backtests, determinations — anything your system derives from the data is yours, and you may sell it without restriction.
- Cache and poll it. Within the rate limit (15,000 requests/min per IP). The SignalR stream is unmetered — prefer it for live prices.
- Keep the last quote for offline or closed-market display. The API supports this natively via
allowStale=true.
The one thing you may not do
Don't resell or redistribute the raw feed. Do not expose biquote quotes or OHLC data through your own API, offer bulk downloads of it as a data product, sublicense it, or operate a competing market-data service on top of it. Using the data inside your product is fine, whatever the product; acting as a data vendor of our feed is not.
What the data is — and isn't
biquote prices are indicative OTC quotes sourced from broker feeds (MetaTrader 5). They are not exchange-licensed data, official index values, or regulated benchmark rates — please don't present them to your users as such. There is no order-book depth, no fundamentals, and no corporate actions. History is shallow by design: roughly a week of hourly bars and about two years of daily bars. If you need deep history, collect it yourself going forward — deeper archives are on our roadmap.
The data is provided as-is, with no warranty of accuracy, completeness, or fitness for any purpose. It is market information, not investment advice. If you make trading decisions with it, that is your decision and your risk — pass allowStale=false so a stale price becomes a 404 instead of a trade.
Service level
The free API — which is currently the only API — comes with no SLA: no uptime guarantee, no advance notice of changes, no support obligation. We run it with care and it is stable in practice, but if your production system needs contractual guarantees, dedicated support, or change notifications, write to us and we'll discuss a commercial arrangement.
Attribution
A visible "Market data by biquote" credit is appreciated and helps the service stay free — but it is not a condition of use.
Fair use and changes
We may throttle or block traffic that abuses the service or circumvents the rate limit, and we may update these terms; the current version always lives at this URL. Material changes will be noted in the date above. Continued use after a change means acceptance.
