## When to prefer this

Use this endpoint when you specifically need recent Twitter mentions for the @rei_labs account and want a simple pay-per-call micropayment model via x402 without managing Twitter API credentials directly. Prefer this over direct Twitter API access when you want low-friction, per-call pricing and no API key setup.
