Orb API
Orb — developer-first usage-based billing platform with real-time metering, flexible pricing model support (per-unit, tiered, matrix, BPS), and a REST API purpose-built for engineering teams.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
SOC2 Type II certified. TLS enforced. Bearer tokens with sandbox/production isolation. Idempotency keys prevent double-billing. Strong SDK type safety reduces implementation errors.
⚡ Reliability
Best When
Your agent product has complex, usage-based pricing with multiple dimensions and you need engineering-grade metering accuracy and real-time billing visibility.
Avoid When
You have simple pricing models or are not engineering-first — Stripe Billing or Chargebee cover simpler use cases.
Use Cases
- • Agents metering API token consumption and billing customers based on actual LLM usage with real-time accuracy
- • Complex pricing models — agents implementing tiered, matrix, or bulk pricing via Orb's flexible price configuration API
- • Real-time usage visibility — agents querying Orb for up-to-the-minute consumption data without waiting for billing period end
- • Credit ledger management — agents granting, consuming, and tracking prepaid credits for customers
- • Revenue analytics — agents fetching subscription metrics, MRR, and usage trends for business intelligence
Not For
- • Simple fixed-price subscriptions — Stripe Billing is simpler for standard recurring billing
- • Non-engineering teams — Orb is developer-first and requires API integration
- • Very early stage (pre-revenue) — overhead of Orb is not justified without billing complexity
Interface
Authentication
Bearer token from Orb dashboard. Single API key per environment (sandbox/production). Idempotency key header support for safe retries.
Pricing
Revenue share pricing model — Orb earns when you earn. Sandbox environment free for development. Enterprise flat-fee options available for predictable costs.
Agent Metadata
Known Gotchas
- ⚠ Events are eventually consistent — ingest returns 200 immediately; balance/usage reflects events after ~30s processing
- ⚠ Price configuration is immutable after use — create new prices rather than modifying existing ones
- ⚠ Customer portal requires separate Orb-hosted URL generation — not directly embeddable without Orb's portal SDK
- ⚠ Sandbox and production use different API keys and separate event streams — don't mix environments
- ⚠ Matrix pricing configuration requires precise price matrix setup — errors at config time cause incorrect billing
