Frequently Asked Questions
What counts as a proof?⌃
A proof is a complete voice verification request that includes both voice hash verification AND an on-chain Solana stamp. Every Keywave proof gives you both authentication and immutable blockchain attestation in a single API call.
Do retries count?⌃
Yes. Each API call counts as a proof, even if retried. Use Retry-After on 429 responses to back off.
How does billing work?⌃
Pure usage-based billing with automatic graduated pricing. You're charged monthly for the exact number of proofs used, with pricing automatically adjusting based on volume. No monthly minimums, no surprises.
What happens if I exceed my rate limit?⌃
You'll receive a 429 response with Retry-After header. Your requests aren't lost. Implement exponential backoff to retry. Contact us to increase limits anytime.
Do I choose a tier?⌃
No. Your pricing automatically adjusts based on monthly proof volume. Use 50K proofs? Pay Pilot rates. Scale to 500K? Automatically get Production pricing. It's that simple.
Are Solana network fees included?⌃
Yes! Every proof includes the on-chain Solana stamp with all network fees absorbed. You never pay extra for blockchain attestation, it's built into the proof price.
Do you support EVM stamping?⌃
Yes. Keywave can optionally mirror Solana attestations to EVM chains using the Ethereum Attestation Service (EAS). This is available by request for Production and Scale users.
Does this replace KYC?⌃
No, PoH proves humanness, not civil identity. Use PoH to block bots up-front; pair with KYC only where the use case mandates identity.
What if users don’t have a mic?⌃
Fallback allowed; we recommend gating high-risk actions with PoH while permitting read-only behaviors without it.
