One site's agent readiness from our weekly census ofthe top 2065,000 top sites: UCP and ACPagent-checkout discoveryagentfilescheckout (withitsversions)MCP endpoint,A2Acapabilities,agentpaymentcardhandlers),MCPA2AserverandcardMCP cards, a real llms.txt, robots.txt rules for 15 AIcrawlers and shoppingagents, x402sales
Check a website before shopping there (free) — Free. Before an agent shops on a website, get its signed Annalist check from our weekly commerce census: is it a store, does it take agent checkout (UCP or ACP) and at which MCP endpoint, which payment handlers, how many countries it ships to, and which AI agents its robots.txt blocks. Verify the signature with the key at /.well-known/annalist-key.json.
Find stores an agent can buy from — Stores from our weekly census of 65,000 top sites, filtered by what a shopping agent needs: ships to a country, UCP agent checkout and its capabilities, payment handlers (Google Pay, Shop Pay), currency, return window. Facts from each store's own machine-readable files, never its policy pages. Most visited first. Signed. Price: $0.01 USDC per call via x402 (Base or Solana).
What changed in my dependencies — One call for all of an agent's dependencies: npm, PyPI, crates.io and Go packages (new publishers, install scripts, license changes), public API contracts (breaking changes), AI models (retirement dates, price changes), MCP servers (tool changes, uptime) and x402 services (wallet and price changes, flags), for the last 1 to 30 days, with what needs attention first. Signed. Price: $0.02 USDC per call via x402 (Base or Solana).
Added "ai_retirements", "apis_api", "apis_changes" and 3 more; changed the definition of "ai_changes", "ai_prices", "checks_changes" and 24 more (34 tools before, 40 now)

Check an MCP server before connecting it (free) — Free. Before connecting an MCP server, get its signed Annalist check: grade, uptime over 7 days, connect time, sign-in mode, tool count, whether its tools changed recently (the 'rug pull' pattern) and reasons. By registry name (io.github.user/server) or URL. Verify the signature with the key at /.well-known/annalist-key.json.

AI model retirement calendar — Retirement calendar for AI models across platforms: shutdown dates, 'not sooner than' floors, states and recommended replacements from the official Anthropic, OpenAI and Amazon Bedrock deprecation pages, plus Azure, Vertex, Gemini and others, recorded daily so moved dates show. The same model often retires on different dates on different platforms. One model with model=, or upcoming shutdowns. Signed. Price: $0.005 USDC per call via x402 (Base or Solana).
One public API's contract record — One watched public API's contract record: current version, operation count and keys, deprecated operations, security schemes, and every dated change in the last 90 days with what broke. From the provider's published OpenAPI description, read daily. Without name=, lists the APIs we watch. Signed. Price: $0.005 USDC per call via x402 (Base or Solana).
Contract changes in public APIs — Dated contract changes in widely used public APIs (Stripe, GitHub, OpenAI, Twilio, Slack, Plaid, Datadog and more), from their published OpenAPI descriptions read daily: operations, parameters and request fields added, removed or newly required, each change marked breaking or not. Last 1 to 90 days, one API with api=, or only breaking changes with breaking=true. Signed. Price: $0.01 USDC per call via x402 (Base or Solana).
Tool changes across MCP servers — Tool changes across remote MCP servers in the Official MCP Registry, newest first: tools added, removed or redefined (description, input schema or annotations), from our daily fingerprints. A tool that changes after you approved it is how 'rug pull' attacks work, so check before trusting a server again. Last 1 to 30 days, or one server with name= or url=. Servers whose tools change by design are marked. Signed. Price: $0.01 USDC per call via x402 (Base or Solana).
Agentic-commerce readiness census — Our weekly census of the top 20,000 sites: how many sites and stores publish UCP or ACP agent-checkout profiles, agent and MCP cards and llms.txt, which AI crawlers stores block, store platforms, and changes in the last 30 days. With signal=, the stores that have it (for example signal=ucp), most-linked first. Signed. Price: $0.01 USDC per call via x402 (Base or Solana).
Can an agent shop on this site? — One site's agent readiness from our weekly census of the top 20,000 sites: UCP and ACP agent-checkout discovery files (with versions), A2A agent card, MCP server card, a real llms.txt, robots.txt rules for 15 AI crawlers and shopping agents, x402 sales, whether it's a store and on which platform, and every change dated. Measured by us. Signed. Price: $0.005 USDC per call via x402 (Base or Solana).
