# Create a Stripe SetupIntent to capture a card for the caller's org

`POST /mu/setup-intents`

## Request

- Base URL: `https://api.mnemom.ai/v1`
- URL: `https://api.mnemom.ai/v1/mu/setup-intents`
- Auth: HTTP bearer

Creates a Stripe SetupIntent (card capture, no charge) for the authenticated caller's organization — the deliberate second ask of Pricing Model v2 (MNE-3255): sign-up needs no card, and capturing one triggers the one-time intro grant when `setup_intent.succeeded` arrives on the webhook (never on this call). Owner/admin only, same org resolution as the purchase route. Takes NO request body — any body sent is ignored; api authors the upstream request entirely from the server-resolved `billing_account_id`. Response is mnemom-billing's verbatim `{stripeCustomerId, setupIntentId, clientSecret}` on 201.

## Query parameters

- `org_id` string

## Response `201`

SetupIntent created (mnemom-billing response, verbatim): `{stripeCustomerId, setupIntentId, clientSecret}`.

- object

## Other responses

- `401`: Authentication required
- `403`: Forbidden
- `404`: Resource not found
- `409`: Resource conflict — the request cannot proceed because of a current state conflict (e.g., resource already exists, version mismatch, in-flight idempotency key with a different body).
- `429`: Rate-limit exceeded. The global per-IP limiter (100 requests/minute, applied to every `/v1/*` route) rejected this request. Back off until the window resets — `Retry-After` carries the cooldown in seconds and `X-RateLimit-Reset` the absolute reset time.
- `500`: Server error — request was well-formed but the server failed to fulfill it. Typically a downstream dependency (DB / RPC / external API) returned an unexpected error.
- `502`: An upstream dependency returned an invalid response.
- `503`: An upstream dependency is currently unavailable. The request was not processed; retry after the cooldown window.
