  note: Corrected 2026-08-13. The previous derived value said "self-serve signup"; there is no self-serve signup. https://www.leadsquared.com/free-trial/
    redirects to https://www.leadsquared.com/book-demo/ (HTTP 200 after redirect), so the only entry point is a sales demo
    request. List prices ARE published for Sales CRM ($60/$100 per user per month) and Marketing Automation ($2,000/$3,500
    per account per year). API keys are issued inside an existing tenant, so a developer cannot obtain credentials without
    a commercial relationship.

    A submission returns a RequestId which is then polled on a matching status endpoint, with a metrics endpoint per operation.
    Requests are accepted and retried up to 10 times even while the core platform is unavailable, which is the documented
    way to keep user-facing capture paths off the 5-second throttle. Authentication adds an x-api-key header to the accessKey/secretKey
    pair; the status endpoints need only x-api-key. Hosts are regional, mirroring the REST API.
