}'Everything a developer platform needs
Keys, credits, metering, limits and analytics — wired end to end, not mocked.
Instant API keys
Create, revoke and regenerate keys. Keys are hashed at rest and shown in full only once.
Credit-based usage
Every request is metered by tokens and deducted atomically — never below zero.
Usage analytics
Requests, tokens, latency and errors, charted by day, week or month.
Secure by default
Provider credentials never leave the server. Row-level security on every table.
Rate limiting
Per-user limits with a clean 429 response, configurable by the platform admin.
Familiar interface
An OpenAI-style chat completions endpoint that drops into existing code.
