Get the plans an account can see, for display in an account-facing UI: the plans set up for its partner, cheapest first. Use this when you're building the plan page a business owner sees. Partners should use List your plans instead.

Prerequisites: with a token, optionally the account's company_id; without a token, the partner's referral_code.

Authentication: Public (no token). With a token, company_id must be inside your own account tree (default: your own company). Without a token, send referral_code; company_id alone is rejected with 422. With neither, the default plans are returned.

Rate limit: 100 requests per minute, counted per client IP address.
