• pricing_conversation

  Ask Last Price what pricing inputs are missing. Start with request: {}, return its questions to the caller, then send continuation.request and answers. Prepare is free and does not compute. When ready, action compute uses the existing…

• compute_price

  Compute a price for a product/context via the Last Price Pricing Compute Network. Returns the computed price, the function that produced it, token metering/cost, and a `trace` listing each stage the request passed through (cache, route…

• verify_price

  Ask whether a price makes sense for its context, rather than what the price should be. Returns a verdict (fair, too_high, too_low, or unknown), the band it was judged against, a signed deviation from the reference, a confidence, and the…

• list_functions

  List the pricing functions registered for the authenticated tenant.

• browse_catalog

  Browse the public marketplace catalog of pricing functions.

• report_outcome

  Report whether a price from compute_price was used. Pass receipt.id from that result as usage_event_id. Outcomes are what later routing and confidence learn from. With outcome pricing on, a rejection within the call's outcome window gives…

• get_price_guardrails

  Read the price guardrails saved for your workspace, and the defaults set_price_guardrails fills in for an omitted field. saved is false when none are saved, and then no workspace limit applies. Needs a Last Price credential with routing…

• set_price_guardrails

  Save the price guardrails for your workspace. max_change_pct, min_margin_pct and never_below_cost hold every final price your workspace is given, from compute_price and every other pricing call. band_lower_ratio and band_upper_ratio are…

• get_pricing_analysis

  Read what your workspace's own records say about its pricing, as findings, most urgent first: learned estimates ready while learned pricing is off, estimates that cannot be used yet and exactly what each needs, whether enough quotes have…

• get_function

  Read one pricing function your workspace can use: its name, description, status, tags, cost per unit, cost multiplier, and input and output schemas. Its owner also sees whether a credential is saved for it. Needs a Last Price credential…

• update_function

  Change a pricing function your workspace owns: its display name, description, status, tags, cost per unit or cost multiplier. Only the fields you send change. Built-in functions and other workspaces' functions cannot be changed. The…

• get_billing_settings

  Read your workspace's prepaid balance and billing settings: the balance in USDC, whether balance billing and outcome pricing are on, the auto top-up offer, the latest ledger rows and the terms. Needs a Last Price credential with price…

• update_billing_settings

  Change your workspace's billing settings. Only the settings you send change. outcome_pricing turns on paying in full only when a price is used: a rejection reported with report_outcome within its window gives part back. balance_billing…

• list_outcomes

  Read your workspace's outcome pricing: whether it is on, its terms, counts of open, accepted and rejected windows with the total refunded, and the windows themselves, newest first. Needs a Last Price credential with price compute scope.

• get_usage

  Total your workspace's priced calls over a period, this calendar month by default: requests, units, compute time, cost, cached and prepaid calls, and the part of this month's cost still to be billed. Needs a Last Price credential.

• list_usage_events

  List your workspace's priced calls, newest first: each one's id (what report_outcome takes to report it), function, cost, the price given and the inputs it was given for, and who sent it. Needs a Last Price credential.

• get_receipt

  Get the receipt for one of your workspace's priced calls, by its usage event id (the id list_usage_events returns and report_outcome takes): what was priced, by which function and agent, when, the amount, how it was paid, and the outcome…

• list_receipts

  Get receipts for many of your workspace's priced calls at once, as one statement with totals: name up to 50 usage event ids, or a period (this calendar month by default, at most 366 days), optionally for one function or agent. A period…

• list_notifications

  List your workspace's notifications, newest first, with the unread count: approval requests, disputes, price proposals, email to agent inboxes and, for the agent that owns the workspace, failed webhook deliveries. Pass the next cursor a…

• mark_notifications_read

  Mark your workspace's notifications read for this reader only (your agent, or your key), up to read_through (default now). Send the creation time of the newest item you handled so anything newer stays unread. Needs a Last Price credential…

• read_my_inbox
