Pricing
The free API is live with no signup, card, or account-level meter. The higher-volume tiers below are proposed prices we are using to learn what teams need; they cannot be purchased today.
Paid tiers are a demand test, not a sale. The public API is live now — free, no signup or card. For a higher-volume plan, request access so we can assess demand. There is no checkout, billing, API-key provisioning, SLA, or commitment yet.

What is live now
The public catalog API is free without signup, keys, or account-level metering. Standard network abuse controls may apply. See the documentation for current endpoints and usage guidance.
How proposed paid access works
Requesting access sends us your use case and expected volume. It is not an order and does not create an account, API key, invoice, or contract. If a paid offering is launched, we will contact requesters with the actual terms before any purchase is possible.
Why show proposed prices?
They make the demand test concrete without pretending the service is available. Tell us what volume and reliability requirements you need by emailing hello@caslonmedia.com or use the request-access page.
