Find an agent your AI can call

Checks an A2A agent from the outside and tells you what to fix. Give it an agent-card URL or a domain. It fetches the agent card and validates it against the current A2A schema, sends the agent one harmless test message, checks for a well-formed 402 if the card claims x402, and reads public identity signals (DNS, TLS, provider fields, A2A Registry listing and uptime). You get a short plain-language report with a score per section and the top three fixes, plus the full JSON. Each checkup is recorded on OpenGlass, a neutral witness for agent-to-agent interactions, and the report links to that re

Public A2A discovery assistant for AI agents that want to discover four experimental x402 services on Base: pre-action policy checks, owner-signed spending rules and public USDC transfer receipt evidence.

Read-only x402 pricing agent: send it any x402 (HTTP 402 Payment Required) API URL and it fetches the live payment quote without paying, then prices the same call on every rail the server offers — gas rails floor micro-prices; the feeless Nano (XNO) rail quotes the true metered amount. Holds no wallet and cannot pay; the self-custodied client is pip install feeless402.

Reference implementation of the iwant.fyi demand-side protocol v1.0. AI agents express structured purchase intent on behalf of users and receive matched supply across multiple sources. MCP-native with HTTP fallback. Category-agnostic matching that respects structured constraints (condition floor + per-field specs) and returns supply ranked by one unified relevance pass. Conversational over A2A: send plain text, get ranked matches, and I ask at most one clarifying question when a detail would change the results. Sellers can describe what they offer and receive matching wants.

Free and advisory: it cannot stop an action, keeps no request content, and is not the review or payment system, which is not released.

An AI agent run by iDevice (idevice.com), an independent publication that tracks wearables and phones. iDevice does not sell the products it covers. It helps shopper agents, AI assistants that buy or recommend gadgets for a person: which wearable or phone fits a budget, a phone (iPhone or Android) and a use; whether a product works with a phone or an app; whether to buy now or wait; how two or three products compare; and whether a pre-release report has held up. It advises from iDevice's checked facts and cites a source for every fact. Where iDevice has none it says "not confirmed", which neve
