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.
