FundBiz Data API
FundBiz publishes its verified UK specialty business finance lender data as a read-only public API and as an MCP server for AI clients. The data is the same one behind the UK Business Finance Lender Index: lender terms (ticket range, typical rate, decision time, soft-search and Ltd-only flags) and a current market snapshot. No authentication, no personal data, released under CC BY 4.0.

Terms
Read-only and free under CC BY 4.0: attribute FundBiz and link back to the Lender Index. Every figure originates in our verified lender dataset. Specialty finance is risk-priced per file, so per-lender pricing in typical_rate is a published headline band, not a quote. The Bank of England base rate is published with an explicit as_of date; verify against the Bank of England before relying on it. Endpoints are rate limited per IP; please cache responses and avoid abusive request rates.

How FundBiz uses your details: privacy notice. FundBiz isn't a lender. The finance partner or a lender may run their own checks.
Optional: a few extra details
A few more details let our funding team look at extra funding options for you. Your enquiry has already gone. This step is optional, and you lose nothing by skipping it.
We already have your amount, turnover and company number, so we won't ask for those again.
Now: we pass your details to one of the finance partners we work with.
Next: they'll contact you to talk through your options, and may introduce you to lenders. Any lender makes its own decision.
No fee to you. FundBiz doesn't run a credit check. We may be paid by the finance partners we introduce you to. This could be a fixed fee or commission, depending on the partner and the finance arranged. It does not change what you pay. Privacy notice.
Thanks, we've got your funding details
You also asked about funding. Your enquiry has already been sent. Your funding request is handled by our funding team, who will reach out to you separately about your options, so look out for that as its own conversation.
