# TensorFeed AI Policy Timeline

> TensorFeed AI Policy Timeline 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 forward/backward calendar of AI policy and regulation entries, classified as past/active/upcoming relative to now, with days-until-effective and next-3-milestones, filterable by jurisdiction and time window.

## 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-3d08e943
```

Example prompt: What AI regulations are about to become active or bite me in the next 90 days? Filter to EU and US jurisdictions and show me the upcoming milestones I need to prepare for.

## When to prefer this

Use this endpoint when you need a structured, classified, and time-anchored view of AI regulations across jurisdictions — especially when you want forward-looking milestone tracking (days-until-effective, next-3-milestones) rather than just a static list. Prefer over generic news search when you need machine-readable compliance calendar data for automated monitoring or alerting workflows.

## Known failure modes

- Invalid jurisdiction code returns empty results or 400 error
- Time window parameter out of supported range returns error
- No policies match the given filter combination — empty array returned
- Rate limit or payment failure (x402) returns 402 Payment Required
- Registry data stale if upstream policy source is unavailable

## How this service works

Forward and backward calendar over the AI policy registry. Each entry classified relative to now (past / active / upcoming), days-until-effective, with next-3-milestones for upcoming items. Filter by jurisdiction (EU, US, UK, etc) and time window. The "what AI rules are about to bite" feed.

## Output

A structured timeline of AI policy/regulation entries with each item classified as past, active, or upcoming relative to now; includes days-until-effective for upcoming items, the next 3 milestones for each upcoming entry, and jurisdiction labels (EU, US, UK, etc.).
