Apiosk is the comparison layer for agentic commerce. Listings are grouped by the job they perform, so an agent that needs a task done gets every provider that can do it in one call, priced side by side, with an input mapping that makes the offers substitutable. Three chained endpoints do the comparing, and none of them charges anything: GET /v1/discover (what can perform this task, with stable candidate ids), GET /v1/compare (how those candidates perform against your requirements, scored 0-100 with the weights and per-dimension contributions that produced the number, so it can be recomputed rather than trusted) and GET /v1/decide (one provider back, the rule that picked it, every rejection with the constraint that caused it, and the runners-up in order). Browse the jobs with GET /v1/capabilities; get the candidates for one, cheapest first, with GET /v1/capabilities/{slug}. The call you pick is paid per request over x402 (HTTP 402 + USDC), with no accounts, API keys or SDKs. Describe a need in plain words at GET /v1/search and get the providers ranked. Price, settlement rail and input compatibility are compared for every offer; measured latency and success rate are published for the listings Apiosk has proxied enough calls of, and explicitly absent for the rest. Result quality is not measured anywhere.

Read-only airport delay, weather, and 24h forecast tools for AI assistants. Airport-level only.

TensorFeed is a real-time AI ecosystem data provider built for agents. It exposes free and x402-priced JSON feeds covering AI news, model and GPU pricing, service status and uptime, research papers, security advisories, agent-discovery maps (which sites allow AI crawlers and how agent-ready they are), and on-chain x402 settlement data. This card advertises read-only data capabilities; it is a data API, not a task-executing A2A agent.
