ChromaGate · Agent Pay

A pay-per-lookup library of provable color palettes extracted from world-class cinematography. Animators and colorists meter their inspiration, paying only for the specific palettes they export into their workspace. Facilitators settle high-fidelity color telemetry on Base, ensuring the original curator gets a micro-royalty for every style 'forked' by another artist. The endpoint is priced in USDC over x402, so an autonomous agent can pay for itself without an API key.

The primitive.

full primer →

The color study curation endpoint publishes its own price, so an autonomous agent can pay and retry with no API key — filmmakers watch a machine buy the answer beside a human doing the same thing.

Why this primitiveLoading details…

Kernel
an endpoint whose price, asset and payee are published in its own 402 response, so an autonomous agent can discover the terms, pay in USDC and retry with no API key and no signup
Drives the UI as
a side-by-side view of the human client and an in-page agent running the same request → 402 → pay → retry loop
