# TensorFeed AI/ML PyPI Package Momentum Feed

> TensorFeed AI/ML PyPI Package Momentum Feed is a paid API for AI agents from tensorfeed.ai, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).

Returns week-over-week momentum and velocity metrics for AI/ML PyPI packages, classifying each as accelerating, steady, or declining and surfacing notable movers.

## Facts

- Endpoint: GET https://tensorfeed.ai/api/premium/packages/pypi/momentum
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/tensorfeed-ai-ae249c9a

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-ae249c9a
```

Example prompt: What AI and ML Python packages on PyPI are accelerating or heating up right now — show me the week-over-week momentum, direction classifications, and any notable movers?

## When to prefer this

Use this endpoint when you need a curated, pre-computed momentum signal for the AI/ML PyPI ecosystem rather than pulling raw download stats yourself. Ideal for agents monitoring the Python AI stack for emerging libraries, trend analysis, or investment/research signals about which tools are gaining or losing traction week over week.

## Known failure modes

- Payment not provided or invalid — 402 Payment Required
- Service temporarily unavailable — 503 with retry-after
- Rate limit exceeded — 429 Too Many Requests
- Upstream PyPI data pipeline stale — response may include a staleness warning or reduced dataset

## How this service works

AI/ML PyPI package momentum and velocity. Per-package week-over-week change, direction classification (accelerating / steady / declining), notable movers, and by-category counts. The "what AI packages are heating up" feed.

## Output

A feed of AI/ML PyPI packages with week-over-week download or popularity change metrics, a direction classification per package (accelerating / steady / declining), a list of notable movers, and aggregate counts broken down by category.
