What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of docs.numeral.com controls every word below.

integrating-numeral-tax-api

Use when integrating Numeral's tax API (api.numeralhq.com) into a checkout, invoice, subscription, marketplace, or order-management flow. Covers the calculate / commit / refund / customer lifecycle and the integration pitfalls that cause duplicate transactions, wrong amounts, or under-collection. Read before writing any client code against the Numeral tax API.

integrating-numeral-with-stripe-elements

Use when integrating Numeral's tax API (api.numeralhq.com) into a Stripe Elements implementation — PaymentIntents (one-time and auth→capture), Stripe Invoicing, Subscriptions via the Subscription API, or SetupIntents. Standalone skill — covers calculate/commit timing for each Stripe flow, the calculation_id-via-metadata handoff between server and webhook, address-change recalculation, and webhook event mapping. Read this when Stripe Elements (any of PaymentElement / AddressElement / Subscription / Invoice) is in the stack.
