Contact usOne billable conversion is a single successful call to /v1/convert, /v1/normalize, or /v1/validate, counted against your monthly quota. Auth, rate-limit, and quota rejections are never billed. The Free tier hard-stops at its cap, while paid plans meter any overage.
Prices shown exclude tax; applicable tax is calculated at checkout. EU/UK business customers can enter a VAT ID for reverse charge.
The Free tier hard-stops at 1,000 conversions/month — further calls return HTTP 429 until the UTC month resets. The 1,000 cap is shared across your test and live keys.
Paid plans never block at the cap. Usage beyond the included volume is metered and billed per 1,000 conversions at the plan's overage rate — from $6.00 per 1,000 on Micro down to $0.50 per 1,000 on Scale, tapering as your committed volume grows.
Yes — Enterprise on-prem runs in license mode: unlimited within the license, rate limiting preserved, on your infrastructure. Contact us for terms.
Free, Micro, Small, Starter, Growth, and Scale are self-serve — start or change them in the dashboard. Enterprise (custom volume, SLA, on-prem) is contact-us.
Prices exclude tax. Stripe Tax calculates and adds any applicable sales tax or VAT at checkout based on your location. EU and UK business customers can enter a VAT ID for reverse charge.
