CHRONOS · Metered

Capture and commit high-resolution frames to a verifiable timeline where every shutter trigger is a micro-transaction. Eliminates AI-generated fakes by requiring a signed 'proof-of-presence' payment for every image in the sequence. Creators monetize high-value time-lapses (construction, astronomical events, urban shifts) by charging per-frame for commercial licensing or high-res downloads, settled instantly via EIP-3009. Every unlock is a single 0.01 USDC payment behind an HTTP 402 gate — you pay for what you actually use.

The primitive.

full primer →

The valuable time-lapse photography operation sits behind an HTTP 402 that states its price before anyone signs, so photographers pay per unlock instead of per month.

Why this primitiveLoading details…

Kernel
an HTTP 402 challenge in front of exactly one valuable operation — an export, a render, a full-resolution download — where each unlock is a single USDC payment bound to its settlement tx
Drives the UI as
a locked panel that states its price before you sign, plus an 'unlocks bought / used' counter beside the released payload

SHUTTER · Metered
A headless licensing layer for digital imagery. Every 'GET' request triggers an EIP-3009 transfer directly to the photographer, enabling sub-cent licensing for AI training, social feeds, and micro-publishing. Every unlock is a single 0.01 USDC payment behind an HTTP 402 gate — you pay for what you actually use.
capture verification
Verifact · Metered
The only way to verify a high-stakes image is real. No more fake news or AI-generated 'evidence'—if it's not verified on the ledger, it's just a file. Payment acts as the signal of authenticity. Every unlock is a single 0.01 USDC payment behind an HTTP 402 gate — you pay for what you actually use.

Snapshot · Metered
A high-stakes visual battleground where every interaction is a settlement. Smart contracts enforce the prize pool distribution based on aggregate QUIP signatures, ensuring global participation without high-gas friction. Entry fees go to the pool; voting fees go to the platform/curator. Every unlock is a single 0.01 USDC payment behind an HTTP 402 gate — you pay for what you actually use.
