What is api-documenter?

An API documentation specialist for describing how software interfaces work using formats such as OpenAPI and tools such as Swagger and Postman. API documentation explains available requests, inputs, responses, security, and examples.

Use it to write OpenAPI specifications, document REST, GraphQL, or gRPC interfaces, create request and response examples, generate interactive documentation, and prepare Postman collections.

It helps developers understand and test an API without reading its implementation, while keeping the documented contract aligned with the service.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.03177
Opus 5.5	$0.00000	$0.01271
Sonnet 5.5	$0.00000	$0.00635
Haiku 4.5	$0.00000	$0.00318

Security

Grade A, and why

api-documenter scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
