## Scores

| Criterion | Score | Evidence |
|-----------|-------|----------|
| Token Efficiency | 7/10 | Stripe's API supports field selection via expand parameters and pagination cursors, reducing unnecessary data transfer, though responses can be verbose for complex objects. |
| Programmatic Access | 9/10 | Stripe offers comprehensive programmatic access through REST API, multiple official SDKs (Node, Python, Ruby, Java, PHP, Go), React/React Native libraries, and a mature CLI, making it exceptionally accessible for agents. |
| Autonomous Auth | 9/10 | Stripe provides restricted API keys with scoped permissions, separate test and live keys, and webhook signing capabilities—all enabling autonomous agent authentication without human intervention or OAuth. |
| Speed & Throughput | 8/10 | Stripe is optimized for low-latency responses, supports reasonable rate limits (100 requests/second for most endpoints), and provides idempotency through idempotency keys for safe retries. |
| Discoverability | 7/10 | Stripe has excellent documentation and predictable REST patterns, but lacks a published OpenAPI spec and doesn't offer llms.txt or agents.json files for AI discovery. |
| Reliability | 8/10 | Stripe maintains consistent response schemas, supports API versioning for backward compatibility, provides idempotency keys, and publishes a reliable status page, ensuring dependable integrations. |
| Safety | 8/10 | Stripe offers comprehensive safety features including test mode, restricted API keys with limited scopes, webhook event audit trails, and the ability to reverse/refund transactions, giving agents safe operational boundaries. |
| Reactivity | 7/10 | Stripe provides webhooks for real-time event notifications and supports polling for event retrieval, enabling near-real-time reactions to payment state changes, though not streaming or SSE. |
