Anthropic

Refund Rules

Anthropic generally does not provide refunds for API usage consumption, as charges are based on actual tokens processed. For Claude.ai subscriptions (Pro/Team/Enterprise), refunds are typically not offered for partial months, but customers may cancel at any time to avoid future charges. Billing errors or service issues may be eligible for credits rather than refunds. No specific refund policy for unused API credits or prepaid capacity is documented.

Credit Policies

Anthropic offers service credits for significant downtime or service degradation issues that prevent API usage. Credits may be provided for billing discrepancies or technical issues that result in unexpected charges. The Admin API provides detailed usage tracking to help identify and dispute billing errors. No automatic credits for unused capacity or downtime under SLA thresholds are documented.

Contractual Terms

API usage follows standard terms with no minimum commitments or auto-renewal for consumption-based billing. Claude.ai subscriptions auto-renew monthly unless canceled. Enterprise contracts may include custom terms with annual commitments, price protection periods, and specific cancellation notice requirements (typically 30-90 days). No standard price increase limitations for API usage - rates can change with 30 days notice. Batch API offers 50% discounts but may have volume commitments.

Integration Complexity

Technical Notes

Authentication via API keys only (no OAuth2) - requires Admin API key (sk-ant-admin...) for usage/billing data. Standard REST API with excellent documentation. Rate limits not publicly documented but generally permissive. Admin API requires organization setup (not available for individual accounts). Usage/cost data freshness is ~5 minutes, suitable for real-time monitoring. Supports detailed filtering by workspace, API key, model, and time granularity (1m/1h/1d). Cursor-based pagination for large datasets. All monetary values returned as decimal strings in cents.
