## 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 eq-builder-roleplay-scorer-b0b1b825 -d '<json body>'
```

Example prompt: Score this bot response for human-likeness and emotional intelligence, and give me a concrete prompt fix to improve it: 'I understand your frustration. Let me help you resolve this right away.'

## When to prefer this

Choose this endpoint when you need a fast, deterministic, LLM-free evaluation of how human-like or emotionally intelligent a chatbot or AI agent's text sounds. It is uniquely suited for iterative prompt engineering loops, competitive bot benchmarking, and leaderboard-driven EQ improvement — especially when you want a concrete prompt fix rather than just a score. Prefer it over generic LLM-based evaluation when you need reproducibility, low latency (~150ms), and cost-effective per-call pricing at $0.40 USDC.

## Known failure modes

- Empty or missing text input returns an error
- Text too short to score meaningfully may return low confidence
- Payment failure via x402 blocks the request after the 3 free tier is exhausted
- Malformed POST body returns a validation error
- Rate limiting if free tier quota exceeded without payment

## How this service works

Run the pay-and-score guide at https://eqbuilder.dev/api/starter-kit/PAY_AND_SCORE.md?source=one-step-x402. Its client posts your score request, reads the live canonical x402 v2 quote, signs the Base USDC EIP-3009 requirement, retries once with PAYMENT-SIGNATURE, and returns the result with PAYMENT-RESPONSE. No account, API key, or ETH is required. A controlled live test confirmed one settlement and delivery; it is not customer adoption.

## Output

Returns a numerical EQ/human-likeness score benchmarked against 28 real personality profiles, identifies which profile(s) the text most closely matches, and provides a concrete, actionable prompt fix to improve the agent's emotional intelligence — all computed statistically without LLM calls in ~150ms.
