Claude API (Anthropic)
The Claude API is Anthropic's developer platform for building apps and agents on Claude models, billed per million tokens. Rates run from Claude Haiku 5.5 at $0.10 input and $0.50 output up to Claude Fable 5.1 at $10 and $50.
Description of Claude API (Anthropic)
The Claude API is Anthropic's developer platform, reached through the Claude Console at platform.claude.com. Developers use it to call Claude models from their own applications and to build agents with what Anthropic describes as managed agent infrastructure. It is a separate product from the Claude chat app: API usage is billed by tokens processed rather than through a monthly subscription, and you need an API key and a funded account. The platform offers documentation, model overviews and data processing terms, including an agreement for US K-12 use.
Anthropic's pricing page lists four current model families. Claude Fable 5.1 is the top tier at $10 per million input tokens and $50 per million output tokens. Claude Opus 5.5 costs $4 input and $20 output, and Claude Sonnet 5.5 costs $2 input and $10 output. Claude Haiku 5.5 is the low-cost option at $0.10 input and $0.50 output for prompts in its base tier, with higher rates for longer prompts. Each model also has separate prices for writing to and reading from the prompt cache, which lowers the cost of repeated context, for example $0.01 per million cached input tokens on Haiku. Anthropic describes Haiku as aimed at high-volume, latency-sensitive work such as classification, extraction and routing, rather than naming coding as its purpose.
No free API tier is stated on the pricing page. Toolsfine notes that this page was assessed by a model built by Anthropic, the same vendor, and was held to the same standard as other tools.
