## 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 needle2-14mb-agentic-llm-decision-brief-cb8efc15

Example prompt: Give me a blunt decision brief on whether Needle2 — the 14MB agentic LLM — is actually suitable for my smart home robot project, without any marketing spin.

## When to prefer this

Use this endpoint when an agent or developer needs an objective, agent-optimized evaluation of the Needle2 14MB LLM for deployment on constrained edge hardware (phones, wearables, robots, smart home). Prefer this over general LLM comparison tools when the specific question is about Needle2's agentic suitability on low-resource devices and you want a blunt, structured decision procedure rather than marketing content.

## Known failure modes

- Payment not included or invalid — returns HTTP 402 with payment instructions
- Invalid method used (only GET/HEAD/DELETE accepted) — schema violation error
- topic query param ignored if malformed
- Service temporarily unavailable — provider-side error
- Empty or null brief if generation fails on provider side

## How this service works

Paid agent-facing brief on Show HN: Needle2: 14MB agentic LLM for phones, wearables, smart home and robots -0. Blunt decision procedure, not marketing.

## Output

A structured JSON response containing a prose decision-procedure brief (the 'brief' field) assessing Needle2's suitability for edge/agentic use cases, along with the model name, topic, generation source (llm/reasoning/deterministic), and an ISO-8601 timestamp. The brief is written for agents, not humans, and follows a blunt decision-procedure format rather than promotional language.
