Everyday tools for AI agents, paid per call with x402: images, markdown, speech-to-text, embeddings.
Scored across 24 tools
Most tools target clearly different resources or actions, such as company lookup, DNS, WHOIS, embeddings, transcription, and field watches. The main ambiguity comes from intentional free/paid pairs like extract_data vs. extract_free and read_url vs. url_to_markdown, though the descriptions do distinguish them.
All names use consistent snake_case and are generally readable and predictable. There is some variation between verb-led names like generate_image and noun-led names like company_lei, but the convention is stable enough for an agent to parse.
With 24 tools, the server is on the heavy side for a single toolbox surface, and several capabilities are closely related variants. However, most tools correspond to distinct utility functions, so the count is borderline rather than excessive.
The toolbox covers a broad range of agent utilities: LLM chat, web reading, extraction, document conversion, embeddings, translation, transcription, image generation, company data, DNS/WHOIS, email verification, and field monitoring. Minor gaps exist, such as general web search or persistent storage, but core workflows are well supported.
