Everything you need between "idea" and "production call".
A one-time code gets you in. Add a password or two-factor auth later if you want them.
One key for everything, or separate keys per project scoped to exactly the APIs they need.
Test keys run sandbox APIs without ever touching your credits — build first, pay when live.
1,000 credits per dollar, every API priced per call. Auto top-up keeps you online.
Every call logged with credits, latency and status — per key, per API, per day.
One billing account, per-member monthly credit allocations. Everyone builds, one invoice.
Buy credits once, spend them on any API. No subscriptions, no expiry on paid credits.
