## 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 dylan-from-2045-field-kit-ai-vendor-cutoff-kit-f11432a0
```

Example prompt: Can you pull up the AI vendor field kit so I know the knowledge cutoff dates and context window sizes for the major LLMs I'm working with?

## When to prefer this

Choose this endpoint when an agent needs a quick, structured, machine-readable reference for AI vendor knowledge cutoffs and context window sizes without scraping documentation sites. It is ideal for agent bootstrapping, pre-task briefing, or when building GO/HOLD gates that depend on knowing LLM freshness. At $0.01 USDC per call it is cost-effective for frequent lookups.

## Known failure modes

- Payment not received (402) – USDC micropayment of $0.01 required before content is served
- Product slug not found (404) – if endpoint path is incorrect
- Cloudflare Worker timeout or cold-start delay
- Malformed JSON response if Worker encounters an internal error
- Rate limiting if called in rapid succession without valid payment

## How this service works

Agent-ready playbooks and language-learning data as JSON, $0.01 USDC per call. Agent ops: deploy-sheet (12 GO/HOLD checks before shipping agent-written code), one-screen-brief (6-field task brief), agent-forgets (State Capsule prompt for drifting sessions), field-kit (AI vendor cutoff kit), agent-skill-pack (5 drop-in SKILL.md skills). Language learning / CJK: kanji-hanzi-manga (characters written the same in Japanese and Chinese but read differently, kana+romaji vs pinyin with tones, false-friend warnings), false-friends (Norwegian/German/Dutch words that trick English speakers, with example sentences). Briefs: signal, signal-07 (sourced AI pricing brief). Full agent products at $1.00 each: orchestration-prompts-4, file-bus-interop-kit, agent-output-acceptance-suite. Free index: GET /products.

## Output

A JSON object containing the 'field-kit' product slug, title, source attribution, optional upsell details, and structured content covering AI vendor knowledge cutoff dates and context window reference data, plus a summary and use-when guidance string.
