## 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-ai-text-rewriter-17897dd3 -d '<json body>'
```

Example prompt: Rewrite this bot reply so it sounds human — target the 'casual_friend' personality profile and show me the before and after EQ scores: 'I can help you with that request. Please provide more details so I can assist you efficiently.'

## When to prefer this

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.

## Known failure modes

- 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

## 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
