AgentsProof Pricing 2026

AgentsProof is a freemium ai agent infrastructure tool that offers 6 key features including Trace LLM and tool calls with one wrapper and get a scored report URL, Scores across goal completion, tool accuracy, step efficiency, output quality and safety, Custom graders written as plain-English rules checked on every run. AgentsProof exists to replace vibe-checking an AI agent with a shareable artifact. The integration is intentionally tiny: install one npm package, call `ap.startRun()` with the input and a goal string that anchors grading, wrap each LLM and tool call in `run.trace()`, and call `run.complete()` — which returns a public URL to a proof report. The report scores the run out of 100 with a breakdown across goal completion, tool accuracy, step efficiency, output quality, safety and anomaly detection, alongside the traced step sequence. Beyond the default LLM grader you write custom graders as plain-English rules that are checked against every run automatically, and you define golden test cases — approved input-output pairs the agent must keep satisfying — grouped into proof suites. The problem it targets is the specific failure mode of shipping agents: someone changes a prompt, something breaks silently, and a user notices before the team does. Because a proof report has a public URL, it also works as external evidence — a way to show a customer or a reviewer that the agent behaves, rather than asserting it. Published drop-in support covers OpenAI, Anthropic, LangChain, CrewAI, the Vercel AI SDK and LlamaIndex, with TypeScript and Python SDKs. The product is in beta, and free-tier eval runs return a 402 from the SDK when the monthly limit is reached rather than silently degrading.
