Cheapest vendor at increasing age-check volume
Same per-check prices and ID Analyzer tier structure, only monthly volume changes. Watch how ID Analyzer's tiered plans catch up to and overtake Didit's flat per-check rate as volume grows.

Why three age-verification vendors bill checks so differently
Age verification became a mainstream compliance line item almost overnight. Texas's App Store Accountability Act took effect January 1, 2026, with Utah and Louisiana running similar laws and the Supreme Court allowing Texas to keep enforcing it through 2026; Australia's under-16 social-media minimum-age law took effect December 10, 2025; the EU's age-verification blueprint app and the UK Online Safety Act add further obligations. None of the three vendors compared here price the resulting per-signup age checks the same way. Didit uses pure pay-as-you-go pricing — a flat $0.10 per selfie-based Age Estimation check, no monthly minimum, no plan to pick. ID Analyzer bundles document-based age extraction (OCR date-of-birth plus face match) into monthly subscription plans — $89/month for 1,000 included checks with $0.12/check overage, up to $880/month for 15,000 included checks at $0.08/check overage — so the effective per-check cost drops the higher tier you commit to. Stripe Identity charges a flat $1.50 per check at every volume, a deliberate simplicity trade-off rather than a volume-discount ladder.
Those three shapes produce genuinely different winners depending on scale. At low volume, Didit's near-zero marginal cost and lack of any minimum usually wins outright. As volume climbs into the thousands per month, ID Analyzer's tiered plans start to close the gap and eventually overtake Didit once a plan's included credits are well utilized — the calculator's table below shows exactly where that crossover happens for your numbers. Stripe Identity's flat rate almost never wins on raw cost once volume exceeds a few dozen checks a month, since it never gets cheaper per check no matter how much volume you send it — its case is really about billing simplicity and using an existing Stripe relationship, not lowest cost. Facial age estimation and document-based verification also aren't perfect substitutes: which one satisfies your specific regulatory threshold matters as much as price, so confirm the required assurance level before picking on cost alone.
この計算機の仕組み
の Age Verification API Cost Calculator compares three vendor billing shapes — Didit (flat pay-as-you-go per check), ID Analyzer (tiered monthly plans with included credits and per-check overage) and Stripe Identity (flat rate, no volume discount) — at your monthly age-check volume. Didit's cost is simply checks × price per check. ID Analyzer picks the cheapest of its three plan tiers — Entry, Advanced, Business — where each tier's cost is plan fee + max(0, checks − included) × overage rate; the tier with the lowest total for your volume is shown as the winner. Stripe Identity's cost is checks × flat rate, with no tier or discount to select.
These are representative pricing shapes based on typical published ranges, not live vendor quotes — actual Didit, ID Analyzer and Stripe Identity pricing can vary by region, check type, negotiated volume and contract terms, and enterprise volume often moves to custom pricing outside these public tiers. Always confirm current pricing directly with the vendor before budgeting, and confirm which check type (facial estimation vs document-based) actually satisfies the regulation you're complying with.
よくある質問
How much does an age verification API cost per check?
Published self-serve rates vary a lot by check type. Didit's selfie-based Age Estimation module lists at $0.10/check with no monthly minimum. ID Analyzer's document-based age extraction runs through tiered subscription plans from $89/month (1,000 credits included, $0.12/check overage) up to $880/month (15,000 credits, $0.08/check overage). Stripe Identity charges a flat $1.50/check with no volume discount at any tier. These are representative published ranges, not live quotes — always confirm current pricing directly with the vendor before budgeting.
Why do App Store Accountability Acts and social-media age laws matter for age verification costs in 2026?
Texas's App Store Accountability Act took effect January 1, 2026 (with Utah and Louisiana running similar laws), requiring app stores and, in practice, many apps to verify a user's age bracket at account creation and get parental consent for minors. Australia's under-16 social media minimum-age law took effect December 10, 2025. The EU's age-verification blueprint app and the UK's Online Safety Act add further age-assurance obligations. None of this existed as a mainstream compliance cost two years ago — it's now a real per-check line item that scales with signups, which is exactly why comparing vendor billing shapes at your actual signup volume matters.
What's the difference between facial age estimation and document-based age verification?
Facial age estimation (Didit's model) analyzes a live selfie and returns an estimated age plus a confidence range — no ID document required, lower friction, and typically cheaper per check. Document-based verification (ID Analyzer's model) scans a government ID, extracts the date of birth via OCR, and cross-checks it against biometric face-match — higher assurance and often required for stricter regulatory thresholds, but priced through bundled per-document credits rather than a flat estimation fee. Which one you need depends on the regulation you're complying with and the assurance level it requires, not just price.
Why does Stripe Identity's flat per-check rate get relatively more expensive as volume grows?
Stripe Identity deliberately prices at a flat $1.50/check with no volume discount tiers — a simplicity trade-off rather than an oversight. Didit's pay-as-you-go rate stays flat too, but starts far lower ($0.10/check), while ID Analyzer's tiered plans get cheaper per check as you move up plan tiers (12¢ → 10¢ → 8¢ overage). Because Stripe's rate never drops with volume, its total cost scales linearly at the highest per-check price of the three vendors — it can still make sense for a low-volume integration that values Stripe's existing billing relationship over the lowest possible per-check cost.
Which vendor — Didit, ID Analyzer or Stripe Identity — is cheapest for age verification?
There's no fixed answer — it depends on monthly check volume and which billing shape fits it. Didit's pure per-check pricing tends to win at low-to-moderate volume since it has no monthly minimum. ID Analyzer's tiered plans tend to win once volume is high enough that a plan's included credits are well utilized, since its overage rate drops at higher tiers. Stripe Identity's flat $1.50/check rate rarely wins on pure cost at any real volume, but may still suit a team that wants one fewer vendor relationship. Run your own volume through the calculator above rather than assuming any vendor's headline price represents your bill, and confirm current published pricing before committing.
