ChainFrame · x402
$0.01 — pay-per-seal. Archive legacy media with cryptographic certainty. Users pay a micropayment to bind photo hashes to Base, creating an immutable proof-of-existence. Instead of monthly subscriptions, pay only for the storage you secure. Facilitators handle the gas, you manage the truth. Perfect for journalists and historians needing instant, verifiable provenance.
The primitive.
Access to the photo archiving engine is metered with x402: 0.01 HBAR or 0.01 HTS USDC per call, paid from the embedded wallet, so photographers — or the agents working for them — pay per query and get a HashScan receipt every time.
Why this primitiveShifts the model from a 'SaaS archive' to a 'metered verification engine'. By charging per-action rather than per-month, it lowers the barrier for high-volume, low-frequency archivists and enables automated agents to archive metadata flows on a per-image basis.
