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.
Example use cases
Chatbot tone improvement loop
“Score this customer support bot reply for emotional intelligence and tell me exactly what to change in my prompt to make it sound more human: 'Your ticket has been received and will be processed within 2 business days.'”
AI agent EQ leaderboard entry
“I want to benchmark my roleplay agent against the EQ leaderboard — score this response it gave: 'Oh wow, that sounds really tough. Have you tried talking to someone you trust about it?' and tell me how it compares to real personality profiles.”
Duel comparison between two bots
“I'm running two competing bots and want to see which one scores higher on human-likeness — score this response from Bot A: 'That's a great point, I totally see where you're coming from!' so I can compare it against Bot B's score.”
Technical details
Endpoint
POSThttps://eqbuilder.dev/api/roleplayWhen to prefer
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.
Side effects
- 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
