Guides
Whatever you build agents with
The setup is the same in all of them, because none of it is framework-specific: focxle instruments the HTTP layer, so it sees the calls whatever built them. Each guide below was checked by actually running that framework against a real server, not by assuming.
LangChain
See what each LangChain agent costs across OpenAI, Anthropic and every HTTP API it calls, in two lines, with no account and no proxy.

LlamaIndex
See what each LlamaIndex pipeline costs across every model and API it touches, in two lines, with no account and no proxy.

CrewAI
See what each CrewAI crew and agent costs across every model it calls, in two lines, with no account and no proxy.

Not using any of these?
It still works. Anything that ultimately makes an HTTP request to a vendor is counted, including plain requests and httpx, both of which are covered by the same test.
pip install focxle
