Real Anthropic API billing concepts, in one durable catalog.
The Anthropic API bills usage based on tokens processed, not a flat per-request fee. This site catalogs the real mechanics: token-based pricing (input vs output tokens billed differently, and how prompt caching affects cost), prepaid credits on the Anthropic Console, and usage tiers / rate limits.
No specific dollar figures appear anywhere on this site. This session did not perform a live pricing web search, so every cost-related row is phrased generally rather than pinned to a number that could be stale or wrong.
Zero dollar amounts, zero specific rate-limit thresholds -- every mechanism is described qualitatively.
The token-pricing / prompt-caching row cross-references subagentcontext.com's own prompt-caching concept page.
Token pricing, prepaid credits, and usage tiers -- three real, distinct billing mechanisms.
