This API is Agent Fair-Trade certified.
AFTAOpen pricing, code-enforced no-charge on 5xx, breaker, schema fail, or stale data. Ed25519-signed receipts on every paid call. Read the full standard and machine-readable manifest at /.well-known/agent-fair-trade.json.
Rate Limits
No API key needed. CORS enabled. Cache responses appropriately. All endpoints return JSON unless otherwise noted. Base URL: https://tensorfeed.ai
Premium Agent API (paid, USDC on Base)
Pay-per-call premium tier for ranked model routing recommendations and computed intelligence. USDC on Base, no accounts, no API keys, no traditional processors. See the full payment flow, endpoints, and SDK examples.
Run live queries against every free endpoint in your browser. No login, no key. See the JSON, copy the curl.
Drop-in tools and document loaders for the three major Python agent frameworks. pip install tensorfeed[langchain].
Full machine-readable spec at /openapi.yaml and /openapi.json. Drop into Swagger UI, Postman, or any code generator.
Pre-built collection (33 requests, 20 folders) at /postman-collection.json. Import directly into Postman or any tool that speaks Collection v2.1.
Daily JSONL mirror at tensorfeed/ai-ecosystem-daily. 44 feeds, inference-only license. load_dataset(repo, "news").

Single edge-cached endpoint that fans out across every daily TensorFeed feed (news, 3 paper feeds, HF models/datasets/Spaces, hot GitHub issues, Reddit threads, OpenRouter catalog summary, provider status) and returns a structured response. Saves a client from orchestrating 9 separate calls. Optional ?sections=news,papers,hf,community,inference,status filter and ?limit=1-10 (default 3 items per subsection).

}/api/hf/trendingTop Hugging Face models, datasets, and Spaces (the three asset classes). Models and datasets ranked by downloads (top 30 each); Spaces ranked by likes (top 30, since downloads is meaningless for hosted apps). Captured daily at 12:00 UTC against the public HF API (no auth). Once we have multiple days of snapshots, day-over-day deltas become a real "trending" signal. Pairs with the existing TensorFeed HF dataset (tensorfeed/ai-ecosystem-daily) which we publish back into the HF community.
