Authonex

Authonex is an identity-verification platform for teams that need document, face, age and watch-list checks alongside risk controls and reusable digital credentials. It suits API-led products and organizations that want the option of running open-source software themselves. Its per-check pricing is low, but the free allowance needs confirmation before it becomes part of a forecast.

Overview

Authonex checks government-issued driver’s licenses, passports, national ID cards and business licenses, then compares the submitted information against sanctions, wanted and other government watch lists. Face verification matches a person to the photograph on an identity document, while age verification supports age-gated services. Enterprise customers can add custom documents, which matters if your users present credentials outside the standard set.

The platform also issues cryptographically signed digital IDs. They can be displayed as QR codes that refresh every 60 seconds, making them more suitable for repeat presentation than a static image. Zero-knowledge proofs can confirm claims such as age without exposing the underlying personal data, a meaningful option for privacy-sensitive access checks.

Key features

Document analysis goes beyond image capture: Authonex checks document format, barcode-data integrity, security features, expiration, revocation, cross-field consistency and fraud indicators. That combination is useful for onboarding and compliance teams that need several authenticity signals in one flow.

Its Risk Engine adds behavioral analysis, device fingerprinting, threat intelligence, real-time scoring, custom rules and blocklists. These controls are relevant when identity verification must be combined with account-abuse or fraud decisions; a team seeking only a simple ID check may not use the broader toolkit.

Developers can integrate through a REST API or libraries for Node.js/TypeScript, Python, Go, React and Flutter, with a command-line tool also provided. The range covers backend, web and mobile projects without forcing one framework. Security claims include AES-256 encryption at rest, TLS 1.3 in transit, and hybrid Ed25519 and Falcon-512 signatures. Authonex states that it is SOC 2 Type II certified, ISO 27001 certified and GDPR compliant.

Pricing

The Free plan costs 0.00 USD, is billed free forever and includes a free trial. Its stated monthly allowance differs by product area: the homepage says 100 verifications, while developer documentation says 1,000. Confirm which cap applies to your account before relying on the free tier.

Cloud verification costs $0.05 per verification, billed per check. Overage fees may apply on paid plans, so high-volume teams should model usage rather than assume a flat monthly bill. Enterprise features, custom integrations and volume discounts are handled through sales, making that route appropriate for organizations with specialized workflows or substantial throughput. Payments are accepted through Paystack, Flutterwave and Payoneer.

Platforms

Authonex is offered as an API, web service and self-hosted deployment. The open-source software is available under the MIT license and can run on your own servers, which gives technically capable organizations more control over infrastructure and data handling. REST access and the listed SDKs support Node.js/TypeScript, Python, Go, React and Flutter implementations.

Who it's for

Choose Authonex for a marketplace, fintech product or age-restricted service that needs document and face checks, watch-list screening and configurable risk signals in one integration. It is particularly suitable when reusable digital IDs, QR credentials or privacy-preserving age proofs are part of the product design, or when self-hosting is a requirement.

It is a weaker fit for a small project that needs a single, unambiguous free quota, a polished consumer app rather than an API, or document coverage outside the standard set without an Enterprise arrangement.

Pros and cons

Pros

• Broad verification scope: document, face, age and government watch-list checks cover more than basic ID capture.
• Detailed document controls: barcode, security-feature, expiry, revocation and fraud checks provide multiple authenticity signals.
• Flexible deployment: API, web and MIT-licensed self-hosting support different infrastructure requirements.
• Privacy and credential options: signed, refreshable QR IDs and zero-knowledge age claims support repeat and data-minimizing verification.
• Low entry price: cloud checks start at $0.05 each.

Cons

• Unclear free quota: the Free plan is described as either 100 or 1,000 verifications per month, so budgeting requires confirmation.
• Potential overage charges: paid plans may add fees beyond included usage.
• Custom documents require Enterprise: organizations with unusual credentials may need a sales-led plan.
• Risk tooling may be unnecessary overhead: teams wanting only straightforward verification may not benefit from the wider engine.

Alternatives

ProntoID is a better starting point for teams wanting a 100-verification developer tier with full API access, sandbox use and community support, plus Android and iOS apps.

Didit suits projects needing 500 full KYC verifications each month on a free plan, including ID, liveness, face match and device and IP signals, with no free trial.

FaceTec is the alternative for a face-focused implementation with self-hosting and free demo or proof-of-concept apps, rather than a broad identity platform.

Shufti offers a free-forever allowance of up to 10 verifications monthly and Android, iOS, API, web and self-hosted access.

Zyphe Age Verification is aimed specifically at age and KYC checks with pay-per-verification billing above its allowance.

AgeChecked is worth considering for Shopify or WooCommerce merchants that prefer commerce-specific plans.

ID.me Authenticator is a free iOS and Android MFA app for the ID.me Wallet, not a general verification stack.

Idswyft is the alternative for an MIT-licensed, self-hosted community edition with unlimited verifications and no rate limits.

Verdict

Authonex is a strong choice for API-driven teams that want document, face, watch-list and risk checks together, with self-hosting and digital credentials available when they matter. Its main drawback is the unresolved Free-plan quota, so choose another provider if predictable free-volume terms are more important than breadth and deployment control.
