Hold a 36-hour expanded-product quote using a workspace key, print-ready PDF and 1–100 US recipients. Returns the exact expiration in expiresAt (UTC). Uploads artwork to DirectMailAmerica for live pricing; no charge or mailing. Each PDF page must match catalog dimensions; postcards require one landscape front artwork page. Two-sided postcard: pro_postcard_85x55, doubleSided:true, color:true, plus reverseMessage OR reverseArtworkBase64; the server assembles two pages. Maximum 25 MiB combined artwork. Staging quotes are demo estimates. Obtain approval of artwork, addresses and total before sending.

Release an immutable saved physical-mail quote using an existing authenticated workspace balance and confirmed=true. Requires approval of the exact artwork, addresses, options and saved total. Can spend the balance and buy postage; insufficient balance stops submission. No funding or checkout. Retry with the same saved quote ID; authorizing or needs_review requires reconciliation. Staging never mails. Email to Postcard quotes require a production workspace credential and the usual OAuth read/write/send permissions.

Advertised destructiveOpen-world
Release the immutable quoteId from quote_letter using an existing authenticated workspace balance. Requires confirmed=true, approvedTotalCents matching the saved quote and one idempotencyKey after review of the exact saved PDF, addresses and options. Changed content requires a new quote and fresh approval. Immediately spends the approved amount and can buy postage. No guest payment, funding or cryptocurrency settlement. Insufficient balance sends nothing. Staging prevents postage but still debits the workspace balance. Reuse the same quoteId and key after interruption; uncertain sends require reconciliation.

}save_cover_sheet — Save Cover Sheet
Advertised destructive
Create or update a reusable workspace cover sheet: name, heading, message, sans/serif font, heading/body sizes and alignment. An empty heading or message omits it. Read list_cover_sheets first; preview changes with render_cover_sheet. Use a new 64-character lowercase hexadecimal id and version:0 to create, or the existing id and current version to edit. A stale version fails; reread before saving again. Use defaultDesign to reset a draft. Maximum 25 designs. Validates fit and preserves fixed envelope address windows. No charge or mailing; does not attach the design to mail or change existing PDFs or saved quotes. Requires OAuth read/write and production workspace access, except the isolated reviewer workspace may save synthetic test designs. Workspace authentication required.

}preview_letter — Preview Letter
Advertised read-only
Render/inspect the exact letter or small postcard PDF and calculate its current price without sending, reserving credits or uploading artwork. Supply exactly one plain-text body or PDF. Covers First-Class, Certified, electronic return receipt, color, duplex, bulk recipients and coupon. Postcards default to included full color; letters default to black and white. Composed preview uses the first recipient. For a small postcard, the primary PDF remains the one-page print artwork; proof identifies a separate two-page PDF showing the approximate white print border and address side. Review that proof, but submit only the original artwork or body, never the proof. Recheck the final price before sending. Workspace authentication required.
