Momentra runs on prepaid credits — no monthly plan. Only two tools spend credits; everything else (search, brief, matching, curation, evaluation, seed) is free.

​
Credits

​
Daily free cap

Never-paid accounts may spend at most 80 free credits per UTC day (and all free accounts together at most 400/day). When a spend would exceed the cap, the tool returns a directive (add credits or come back tomorrow) rather than doing the work — no partial charge. Paid accounts (any credit top-up) are not daily-capped.

​
Billing responses

When a paid tool is called without enough credits (or before linking), it returns a success-shaped directive — not an error — carrying a checkout link the host can surface:
status is auth_required or insufficient_credits. The tool does no work and charges nothing in that case — the agent pays, gets credits, and retries.
A token comes from either the OAuth/CIMD flow (0-credit account) or a Stripe checkout (grants 100 free credits on first create). Both bind to one credit account; top-ups add credits (top-up only — no subscription).

​
Mint or top up a token

Returns a hosted Stripe Checkout URL; the token is bound on checkout.session.completed.

Access and availability

  • Your assistant works with the organizations available to your account. Adding an organization with index_org makes it and its events available to you.
  • Coverage of any organization depends on what it publishes on its own website; Momentra reads the published calendar and does not follow external ticketing or aggregator sites beyond recording their links.
