# TensorFeed AI APIs Feed (APIs.guru AI-filtered)

> TensorFeed AI APIs Feed (APIs.guru AI-filtered) is a paid API for AI agents from tensorfeed.ai, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-13).

Returns a filtered, timestamped feed of AI-relevant APIs from the APIs.guru OpenAPI directory, with per-entry first_seen_at timestamps enabling detection of newly added AI APIs within any time window.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability tensorfeed-ai-694f5ec1
```

Example prompt: Can you pull the TensorFeed AI APIs feed and tell me which new AI-related APIs appeared in the APIs.guru directory in the last 7 days?

## When to prefer this

Use this endpoint when you need to discover AI-relevant APIs from the APIs.guru directory with temporal awareness — specifically when you need to answer 'what new AI APIs appeared in the last N days,' a diff capability that APIs.guru itself does not provide. Prefer this over scraping APIs.guru directly or using generic API directories when AI-domain filtering and recency tracking matter.

## Known failure modes

- Payment not provided or invalid — 402 response requiring x402 USDC payment
- APIs.guru source temporarily unavailable — stale or empty feed returned
- Rate limit exceeded — throttling response
- No new AI APIs in the requested window — empty diff result

## How this service works

AI-relevant APIs from the APIs.guru directory of 2400+ OpenAPI specs, filtered via curated keyword matching. Per-entry first_seen_at against TensorFeed snapshot history so an agent can answer "what new AI APIs appeared in the last 7 days": a diff APIs.guru itself cannot provide. CC-BY-SA 4.0; source links preserved.

## Output

A curated list of AI-relevant API entries sourced from APIs.guru, each enriched with a first_seen_at timestamp from TensorFeed's snapshot history, enabling diff-style detection of newly appeared APIs. Includes API name, description, spec links, and AI-relevance metadata. Licensed CC-BY-SA 4.0 with source links preserved.
