POSTERIOR · ACCESS
Pricing

Public receipts first. Live access only when you need it.

Posterior is priced like a research desk, not a tout sheet. Free surfaces show the record. Pro unlocks the live almanac. Builder exposes the API for teams, researchers, and internal tools.

Is Free a trial?

No. Free is the public proof layer: resolved examples, delayed ledger, news, and board previews stay visible without a subscription.

Does Pro promise profit?

No. Pro shows probabilities, market context, and conservative risk references. Posterior publishes losing days and calibration drift instead of promises.

What does Builder API add?

Builder adds machine-readable access for teams and researchers who need the same probabilities, calibration buckets, and player context in JSON.
