# TensorFeed AI Package Release Velocity

> TensorFeed AI Package Release Velocity is a paid API for AI agents from tensorfeed.ai, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-15).

Returns release velocity metrics (24h/7d/30d counts, semver bump classification, breaking-change flag) for AI/ML packages on PyPI and npm, with notable-movers lists

## Facts

- Endpoint: GET https://tensorfeed.ai/api/premium/packages/releases/velocity
- Price: $0.02/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-f36f1e86
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_DNh46O8KUfO-phYm46_MG

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-f36f1e86
```

Example prompt: Can you check which PyPI agent-framework packages have had a major or breaking version bump in the last 30 days, and show me the ones with the fastest release cadence this week?

## When to prefer this

Use this endpoint when you need to know whether AI/ML dependencies are actively changing and whether those changes are breaking — particularly for automated dependency audits, CI/CD pipelines, or agent workflows that need to stay current with the fast-moving AI package ecosystem. Prefer this over generic npm/PyPI APIs when you need pre-filtered AI/ML scope, semver bump classification, and breaking-change detection in a single call.

## Known failure modes

- Unknown ecosystem or category string returns empty result set or 400 error
- Package substring yields no matches, returning empty list
- Payment not attached or invalid returns 402 Payment Required
- Rate limiting or quota exhaustion returns 429
- Stale data if upstream package registry feed is delayed

## How this service works

AI-package release velocity. Per-package releases_24h / releases_7d / releases_30d, latest bump classification (major/minor/patch/prerelease, pre-1.0 minor counts as major per semver), is_breaking_recent flag (major bump within 30 days). Notable movers: recent_major_bumps, most_releases_7d, fastest_cadence_30d. Filter by ecosystem (PyPI/npm), category (llm-sdk, agent-framework, etc), or package substring. The "what AI deps just changed and is it breaking" call.

## Output

Returns per-package release counts over 24h/7d/30d windows, the latest semver bump classification (major/minor/patch/prerelease, with pre-1.0 minor treated as major), an is_breaking_recent flag for major bumps within 30 days, and notable-mover lists: recent_major_bumps, most_releases_7d, fastest_cadence_30d. Filterable by ecosystem (PyPI/npm), category (llm-sdk, agent-framework, etc.), or package substring.
