change_order_createRaise a change order against a quote or work order and return its CO-YYYY-NNNN number: the reference, the client, a title, the date, and the original contract value in minor units. Free tier: 5 open.

change_order_add_lineAdd one line to a draft change order: added or removed with a quantity and a unit price in minor units, or changed with the old and the new quantity and price, each with a reason and a date. Free.

change_order_statusMove one change order along and stamp the date and note: draft to sent, sent to approved or rejected, either to void. Backwards steps, an unsent approval and a backdated move are all refused.

change_order_getReturn one change order in full by CO number or client: every added, removed and changed line with its reason and delta, VAT, delta gross, the status history and the running value. change_order_list finds the id.
change_orderstringrequired
change_order_listList change orders newest first with status, reference, client, currency and net delta, and above them the APPROVED and the pending delta per currency, kept apart. Filter by reference, status, client, date.

change_order_deleteDelete a DRAFT change order with no lines, freeing an open slot. One sent, approved, rejected or voided is refused, and so is one carrying lines: void it with change_order_status instead. The number is not reissued.
change_orderstringrequired
contract_valueThe running value of one quote or work order: original, approved deltas and current value, with pending draft and sent deltas kept apart. Net of VAT. A reference with no change order is refused.
referencestringrequired
change_order_documentRender one change order as a plain-text document for the client to approve: every line with its reason, the delta net and gross, the contract value before and after, and an approval block. The same text also comes back as a .txt download link valid for one hour. Pro.
change_orderstringrequired
change_order_invoice_payloadBuild the approved delta as invoice_create-ready items in MAJOR units and quote_create-ready items in MINOR units, with VAT at the shared profile rate. Writes nothing and creates nothing. Pro.

license_statusReport 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.
license_activateTurn 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.

Availability history
Each block is one measurement round. Green: working response. Amber: responded but the server was returning errors (5xx). Red: no response at all.
Era history
Each cell is one probe run. Faded cells are incomplete probes — one leg did not answer, so the era is inconclusive.
Response time history
The two probe legs separately: modern server/discover and legacy initialize.
Event log
Derived by comparing consecutive probes — changes in era, protocol version, build and reachability.
