API
Free, read-only JSON access to summary metrics from our cache. No key required. Deliberately bounded: summary-level derived data with small page caps — full chains and the historical snapshot archive live on the site pages, not the API. Research and information only.

Responses come from our own database — the API never triggers upstream vendor calls. Requests are rate-limited per IP; bulk extraction, database reconstruction and commercial republication are prohibited (see Terms). Attribution to Options Band is required when figures are republished.
