get_v1_marketing_promos_code_eligibility
Prices a promo against a plan and seat count. It is PURE: nothing is redeemed, credited or counted, so it is safe to call from a pricing page on every keystroke.
Prices a promo against a plan and seat count. It is PURE: nothing is redeemed, credited or counted, so it is safe to call from a pricing page on every keystroke. An inactive promo or an exhausted cap quotes ineligible with the reason rather than erroring.
| Tool | get_v1_marketing_promos_code_eligibility |
| Door | https://api.hanzo.ai/v1/mcp |
| Method | tools/call (JSON-RPC 2.0) |
| Arguments | 3, 1 required |
| Operation | GET /v1/marketing/promos/{code}/eligibility |
| Product | cloud |
Arguments
| Field | Type | Required | Default | Values | Description |
|---|---|---|---|---|---|
code | string | yes | — | — | Code is the promo code from the path. |
plan | string | — | — | — | Plan is the plan being priced: pro, max or team. Anything else (including the free Developer plan) has no list price and so nothing to discount. |
seats | integer | — | — | — | Seats is the Team seat count; 0 means 1, and it is ignored for the single-seat plans. |
tools/list declares a type and a description for each field and nothing further. The Required column is taken from GET /v1/marketing/promos/{code}/eligibility, the operation this tool dispatches to — the same declaration the REST API validates against. A — means neither the door nor that operation constrains the field.
Call it
A tools/call carries every argument in one flat object — nothing binds to a path or a query string. This call carries exactly the arguments the operation requires, so it is the smallest one that can run.
curl -X POST https://api.hanzo.ai/v1/mcp \
-H "Authorization: Bearer $HANZO_API_KEY" \
-H "Content-Type: application/json" \

}'Values are the operation's own defaults and enumerated values where it declares them, and a <placeholder> where neither source declares one. tools/list needs no credential; tools/call does — called without one the door answers HTTP 200 with a JSON-RPC result whose isError is set and whose text says what was missing.

How is this guide?
get_v1_marketing_promos
Returns every promo the deployment offers with its live counters: how many orgs have redeemed it and how many redemptions remain under the cap.
get_v1_marketing_promos_code_redemption
Returns the caller org's OWN redemption of a promo — an org-scoped read, so it can never surface another tenant's.
