proof.holdings Pricing

Simple, transparent pricing. Pay for proofs, not messages.

Custom Branding (All Plans)

All plans include custom branding on shared infrastructure:

Custom branding lets users see YOUR context in messages:

BYOC - Bring Your Own Channels (Enterprise)

Full channel ownership - users interact with YOUR endpoints:

BYOC = complete channel ownership. Users never see proof.holdings.

FAQ

How does billing work?

• Overage charged at end of cycle
• No long-term contracts

Can I change plans?

• Upgrade anytime, prorated
• Downgrade at end of billing cycle
• No penalties

Do unused proofs roll over?

• No, included proofs reset monthly
• PAYG overage has no expiration

Is there a free trial?

• PAYG includes 1,000 free proofs/month
• No credit card required to start
• Test mode (pk_test_ keys) is always free with unlimited verifications

What exactly is test mode?

• Use pk_test_ API keys instead of pk_live_ — all API calls work identically
• No real messages are sent (SMS, email, WhatsApp, Telegram are all simulated)
• Use the test-verify endpoint to auto-complete verifications instantly
• Test verifications don't count toward your monthly quota or billing
• Webhooks still fire (with "test": true flag) so you can test your integration end-to-end

What's the difference between Business and Enterprise?

• Enterprise (custom): BYOC - your own Telegram bot, WhatsApp number, dedicated infrastructure
