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 rewritten version of the input text that scores higher on human-likeness against the specified personality profile, along with before and after EQ scores demonstrating the improvement quantitatively using pure statistical (non-LLM) analysis
Example use cases
Customer support bot humanization
“My support bot's draft reply sounds robotic — can you rewrite it targeting the 'empathetic_helper' personality profile and show me how much more human it sounds? Here's the draft: 'Your ticket has been received and will be processed in 1-3 business days.'”
Sales chatbot personality tuning
“Rewrite this sales bot message to match the 'enthusiastic_professional' personality profile so it sounds like a real salesperson wrote it, and give me the before and after humanness scores: 'Our product offers numerous benefits that may align with your business needs.'”
AI companion app voice matching
“I need this AI companion reply rewritten to match the 'warm_conversationalist' personality profile — it sounds way too stiff right now. Here's the text: 'That is an interesting perspective. I appreciate you sharing your thoughts with me today.'”
Technical details
Endpoint
POSThttps://eqbuilder.dev/api/rewriteWhen to prefer
Choose this endpoint when you need to improve an AI-generated text's human-likeness before sending it, especially when you want quantified before/after proof of improvement against a specific personality profile. Prefer this over generic LLM rephrasing when you need deterministic, non-LLM scoring (~150ms), personality-profile targeting across 28 real profiles, and a verifiable quality metric rather than subjective improvement.
Side effects
- Invalid or missing tx_hash causes payment verification failure
- Unrecognized target_profile name returns an error or falls back to default profile
- Empty or very short proposed_text may produce poor rewrite quality
- Payment not confirmed on-chain leads to authentication rejection
- Malformed wallet_address causes transaction lookup failure
