FAQ
Nebula is a financial technology company, not a bank. Deposits are held at FDIC-insured partner institutions and cards are issued by a regulated partner. What we build on top is the part traditional banks do not have: a ledger whose native dimensions are agent, model and environment.
One API call creates a virtual card bound to a policy — a monthly ceiling, a merchant allowlist, an environment, an expiry. The agent receives a scoped credential, never your production keys. Revoking it is a second call and takes effect at the network level within a second.
It cannot, by design. Limits are enforced when the authorisation is requested, before money moves, so a runaway loop is declined rather than discovered on the invoice. Every decline is logged with the policy that fired and the agent that triggered it.
No. Most customers keep their operating account where it is and route inference, cloud and agent spend through Nebula. Connecting vendors is read-only by default, and historical spend is backfilled so your first month is comparable.
Your transaction data is never used to train models and is never sold. Vendor credentials are held in an isolated vault, agents see only the data a task requires, and every access is written to an immutable audit log you can query.
There is no monthly platform fee on the Growth plan. You pay a small basis-point spread on card volume and a per-payout fee on international transfers. The pricing estimator below shows what a company of your size actually pays.
