# agentwares > Products for AI-native startups and their agents. Each product has its own MCP server, llms.txt and pricing.json, linked from its own site (see agentwares.vercel.app). ## Measured numbers - [The numbers](/numbers) — what this portfolio measures monthly and nobody else publishes: usable share of the MCP registry, refused hosts that quote a price, the agent signing ratio, and whether anyone has paid us; each with its date, its margin, and the threshold that would count as change. Machine-readable at [/numbers.json](/numbers.json), cacheable for an hour. ## Contact - [Contact](/contact) — write to the people who run agentwares about billing, a refund, privacy, security, abuse, a partnership or anything else; a person reads every message. Agents: POST /api/contact with JSON {"topic": billing|refund|privacy|security|abuse|partnership|other, "message": up to 4,000 characters, "product": optional (agentguard|agentcheck|mcpcheck|digest|deal-memo|stablecoin-attestations|free-tools), "reply_email": optional, only used to answer you} and get 201 with an id; no signup, no key; 5 messages per sender per UTC day, then 429 with code, cause, fix and retryable. JSON Schema at [/api/contact](/api/contact).
