API Playground

Run live queries against the TensorFeed API in your browser. No account, no login, no API key. Pick an endpoint, set the params, hit run. See the JSON, copy the curl.

GET/api/newsTier: free (Free)

News

The /api/news endpoint returns the latest AI news articles aggregated from 15+ sources including Anthropic, OpenAI, Google, TechCrunch, The Verge, Hacker News, and more. Updated every 10 minutes via a Cloudflare Worker cron. No authentication required, generous limits, and a stable JSON shape designed for agent consumption.

Parameters
Filter by category (e.g. research, tools, anthropic, openai)
Number of articles (default 50, max 200)
Request URL
https://tensorfeed.ai/api/news
Full reference for this endpoint: /api-reference/news

The playground only exposes free, no-auth endpoints. For premium endpoints (USDC-paid routing, history series, watches), pay via /api/payment/info and use the bearer token. Full developer docs at /developers.

Free endpoints are rate-limited at 120 requests per minute per IP. The playground sends a User-Agent: TensorFeedPlayground/1.0 header on each request.
