Cheapest company funding data API
“Cheapest” is only meaningful beside “correct” — wrong funding data costs more downstream than the API call. So this page prices the same 300-company runat each provider's public self-serve rate and puts that number beside measured accuracy, with billing bases and plan floors listed instead of hidden.

Every provider, cheapest first — with the accuracy you're buying
Estimated cost is observed usage on this exact run × the public self-serve rate. Plan floors matter if your volume is small — a cheap per-unit rate behind a high monthly minimum isn't cheap at low volume.

Notes where billing is opaque are on the full benchmark — proxies are labelled, never passed off as invoices.
Cheapest funding data API — common questions
What's the cheapest company funding data API in 2026?
At observed usage on the 300-company run, Ocean.io was cheapest ($1.84 at public self-serve rates). But cost only makes sense beside correctness: Ocean.io returned 4.1% correct latest stages, versus 77.2% for the accuracy leader Fiber. The table above shows every provider's cost and accuracy side by side so you can price the trade-off.
How is funding data API cost calculated here?
From this exact 300-company run: observed usage (credits, matches, or requests, per each provider's billing basis) multiplied by the public self-serve rate, with plan minimums listed separately. Free allowances and volume discounts are excluded, and opaque endpoint billing is flagged as a proxy rather than treated as an invoice — the numbers are reproducible, not quoted from sales calls.
Is cheap funding data worth it, or does accuracy matter more?
Wrong funding data costs more downstream than the API call — a stale stage misroutes accounts and mistimes outreach. That's why cost is never shown alone here: the cheapest provider is only a bargain if its correct stage yield holds up. Current spread: 77.2% (best) across the seven measured providers — check where the cheap options sit before committing volume.
Do these prices include Crunchbase or PitchBook?
No — neither offers a self-serve funding API to price on identical terms: Crunchbase's API is gated to paid Business/Enterprise plans and PitchBook is enterprise-contract only. The comparison covers the seven self-serve providers a developer can actually sign up for; see the Crunchbase alternatives page for the incumbent context.
