Provenance Attestation

A signed manifest for an asset or snapshot: asset ID and version, SHA-256 content hash, CC0 confirmation, our "made by humans, no generative AI" attestation, contributor chain of custody, and capture metadata.

It's signed with Ed25519, and our public key is published so buyers can verify it independently rather than take our word for it.

Companies pay for the warranty, not the (already free) assets - a document your own legal or compliance review can point to. That matters more every year in an AI-training and compliance-heavy world where "can you prove this was clean and human-made" is a real question. Bespoke, negotiated per case - contact us to discuss it.

Bulk Snapshots

A point-in-time export of exactly the files, formats, and resolutions you need, cut on demand and delivered directly, without depending on our live API or infrastructure.

It's a good fit for embedded asset libraries, internal mirrors, AI datasets, and any product that needs a fixed, reproducible asset set. Every snapshot ships bundled with its own provenance attestation manifest.

This isn't a recurring product or a self-serve download - each snapshot is a bespoke, negotiated contract. Contact us to scope one out.

Sponsored Projects

Sponsored projects fund real work: HDRI trips, texture collections, scanning equipment, processing hardware, and site infrastructure.

This is not just brand placement. Companies fund a specific outcome that benefits both their team and the wider community.

Sponsorship benefits still scale with contribution size, from acknowledgements and logo placement through to deeper collaboration.

Why Companies Work With Us

The assets and the API to reach them are free, forever, for everyone. Companies that depend on the library in production still choose to fund the operational layer around it:

• A signed, independently verifiable provenance and CC0 warranty for legal or compliance review.
• A reproducible bulk snapshot, delivered directly, with no dependency on our live infrastructure.
• A direct relationship with us if your product depends on the library in production.
• Supporting the continued creation of new public-domain assets.
