}Redeem Promo
Redeem a promo code on a FRESH org — no Checkout, no card.
A promo code lets you continue without entering a card. This creates the
subscription server-side with the coupon attached (the self-serve twin of the manual comp flow), stamps
metadata.organization_id so the subscription webhook grants tier +
POC cap, and sets the org’s plan fields inline so the user continues
IMMEDIATELY (no webhook-latency paywall).
Only codes whose window bills $0 (percent_off=100 — every POC code by validated shape) can start service card-less: a partial discount with no payment method would generate a FAILING first invoice (service cut + dunning — strictly worse than the card form; the uncollectable shape POC-PROMO-CAP-2026-07-17 exists to prevent). Partial codes get a clear redirect to checkout, where the discount still applies. Card-ask happens at coupon end (finances’ T-7d lifecycle).
Every failure carries a reason — never a silent no-op.

}Authorizations
Mixpeek API key, sent as Authorization: Bearer mxp_sk_.... Create one in Studio under Settings → API Keys, or with an admin key via POST /v1/organizations/users/{user_email}/api-keys. A missing header returns 403; an invalid or revoked key returns 401.
Body
1 - 64Plan slug to start on the comped window (product_tier, e.g. managed_build). Must be self-serve and match the code's product restriction.
Signup questions — persisted server-side for GTM attribution, parity with the card path (the no-CC cohort is the highest-sales-relevance cohort; client-event-only isn't joinable with the server-side funnel data). The $5/answer credit is NOT minted here — the comped window bills $0, so there is nothing to offset.
