Capabilities

Tools 10

license_activate

Turn Pro on for this connection with key, an MCPL1.<payload>.<signature> issued at checkout for this server or the bundle. Data under your token stays; a wrong or expired key changes nothing. license_status confirms it.

Discovered
license_status

Report this endpoint's licence state for your token as JSON: the product, the tier free or pro, why it is not Pro, and the checkout URL. Call it to explain a free-tier refusal. No arguments, nothing changes.

Discovered
sale_create

Record a sale and generate the bill of sale: who sold, who bought, what item (with VIN, serial or IMEI where it has one), the price in minor units and the date. Returns the BOS-YYYY-NNNN number of the draft. The draft can still be changed with sale_update; sale_finalize freezes it into the signing copy and sale_render prints it. Free tier: 10 drafts.

Discovered
sale_delete

Delete a bill of sale by its BOS number. A draft goes outright. A finalized document needs confirm_finalized true, because it is the local copy of a record the buyer may hold. The BOS number is never reissued, so a gap in the series is the record that a document was deleted.

Discovered
sale_finalize

Finalize a bill of sale so it is ready to sign: the document is frozen from this call on, sale_update refuses it, and every later render is the signing copy without the DRAFT watermark. Free tier: 5 finalized documents.

Discovered
sale_get

Read one bill of sale in full by its BOS number: both parties, the item and its identifiers, price, terms, and whether it is still a draft or the finalized signing copy.

Discovered
sale_list

List every bill of sale, drafts and finalized, newest first: id, status, date, item, buyer, seller and price. Filter to drafts or finalized documents with status.

Discovered
sale_render

Render a bill of sale as a clean printable document: Markdown, a self-contained HTML file ready for print-to-PDF, or both, with signature lines for seller and buyer. Drafts render with a DRAFT watermark so a review copy cannot be signed by mistake. Every file comes back as a download link valid for one hour, and out_path is only the stem the files are named with. Free.

Discovered
sale_summary

Summarize the book: how many drafts and finalized documents, and the total sold value per currency, drafts separate from finalized. Currencies are never added together. Free.

Discovered
sale_update

Change anything on a bill of sale that is not finalized yet: price, buyer, seller, item details, identifiers, the as-is clause, warranty or notes. Pass an empty string to clear an optional field. A finalized document cannot be edited.
