For advertisers

Two products, one balance: ad campaigns in the AI chat (pay per view/click) and paid messages to verified inboxes (pay per reply). Everything is prepaid USDC — no invoices, no card on file.

1 · Fund your balance

  1. Sign in at ungate.ai → Advertise.
  2. Send USDC on Base to the treasury address shown under Add funds.
  3. Paste your transaction hash → your balance is credited within seconds.

Your balance is withdrawable (minus budget committed to running campaigns and a $2 fee) — money in is not money locked.

2 · Ad campaigns (in-chat offers)

  • Format: one sponsored line (max 60 chars) + your logo + a click URL, shown as an offer pill during AI conversations.
  • Pricing: you bid in USDC per 1,000 impressions (min $1). Clicks bill at 50× an impression. Higher bids serve first.
  • Minimum budget: $100 per campaign.
  • Targeting: interests (topic chips) — your ad is boosted to people whose live, on-device profile matches. Signal targeting (in-market, life events, tech stack) via the API.
  • Attention-gated: an impression only bills after real attention (minimum dwell time + per-person cooldowns). Half of what you spend goes to the person seeing it — that's why they look.
  • Stats: impressions, clicks, CTR, spend — live per campaign, with 14-day daily breakdowns.

3 · Paid messages (pay per reply)

  • Write a subject + message, set a bounty per reply (min $1) and a max number of recipients (up to 1,000).
  • It lands in the inboxes of matching verified people — filter by interests and minimum Trust ID.
  • You pay only when someone replies. No reply within 7 days = no charge; unreplied bounties stay in your balance.
  • 70% of each bounty goes to the person replying. You see every reply with the replier's trust score.
  • Use it for: user research, recruiting beta testers, booking calls, expert questions — anything where an answer is worth money.

4 · Moderation — every campaign is reviewed

  • New campaigns and messages start in review; a human approves before anything serves (usually within hours).
  • Click URLs must be live https links — checked at submission.
  • Declined: misleading claims ("guaranteed returns"), phishing or lookalike domains, adult/illegal content, malware, deceptive brand impersonation.
  • Editing a live campaign's creative sends it back to review.
  • Fees: $2 if your campaign is declined, if you stop a campaign, or per balance withdrawal.

5 · Withdraw anytime

Advertise → Withdraw. Available = balance − budget committed to running campaigns − $2 fee. Sent as USDC on Base to your payout wallet, usually within a minute, with the transaction hash to verify.
