get_letter_statusNo charge. Read stored job status and tracking by id with OAuth or a key for the owning workspace. Does not itself refresh mailing status. Inspect the body for not_found.
list_jobsNo charge. List recent jobs in the authenticated workspace; default 20, maximum 100. Pass the last returned job id as before to continue. MCP structuredContent returns {jobs:[...]}; the text content retains the JSON array for existing clients.
get_pricingCalculate a public USD physical-mail quote from mail class, page count, recipient count, print options and optional coupon. No account or charge required; an authenticated request also reports the existing workspace balance. A quote does not send mail, initiate checkout or fund…

preview_product_quoteDownload a saved quote's exact artwork PDF. All small and double-sided postcards include the selected recipient's illustrative address side; postage placement may vary. Other products return stored print artwork. Review before send_product_quote; reading never changes the quote…
