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, along with a concrete, actionable prompt fix recommendation to improve the score. Response arrives in approximately 150ms with no LLM calls involved — pure statistical scoring.
Example use cases
Optimizing customer support bot tone
“Run this customer support reply through EQBuilder's stress test and tell me how human-like it sounds and what I should change in my prompt: 'Your ticket has been received and will be processed in 2-3 business days.'”
Pre-launch chatbot quality check
“Before I ship my new sales chatbot, can you stress-test this sample reply on EQBuilder to see how it scores on emotional intelligence and what personality profiles it matches: 'Hey! Great to hear from you — I'd love to help you find the right plan.'”
Duel prep — improving bot EQ score
“I want to climb the EQBuilder leaderboard. Score this response from my agent — 'I hear you, that sounds really tough, and I want to make sure we get this resolved for you' — and tell me exactly what prompt change will push the score higher.”

Endpoint
POSThttps://eqbuilder.dev/api/stress-testWhen to prefer
Choose this endpoint when you need fast (~150ms), deterministic, LLM-free emotional intelligence scoring of AI-generated text — particularly when you want actionable prompt improvement suggestions alongside the score. Prefer it over general sentiment analysis when the goal is specifically measuring human-likeness or EQ against a diverse set of personality archetypes, or when you want leaderboard-comparable scores for competitive benchmarking of bots.
Side effects
- Missing or empty proposed_text field returns an error or zero score
- Invalid or unconfirmed tx_hash may result in payment validation failure and rejected request
- Malformed wallet_address causes payment attribution to fail
- Rate limiting or 402 payment required if no valid x402 payment is attached
- Very short or nonsensical text may produce low-confidence or edge-case scores
