Give your AI a spending limit

An AI that spends money doesn't hesitate — it just does it. So you set the rules: how much per payment, how much per day, who it may pay. Anything beyond gets blocked on the spot — and you can stop everything in one click.

① Set the rules for your AI

Like an allowance: set the caps and purpose — anything beyond simply won't go through.

Name itWhat for (optional)Max per payment (USDC)Max per day (USDC)

Only these payees (optional, one per line; empty = any payee)

③ Where my money went

No records yet. Once your AI pays with this key, allowed and blocked attempts show up here.

What do I do with the key?

Configure the key in your AI or script and have it pay through OceanAlt. Every payment is then checked against your rules — compliance, limits, payee, purpose — and only goes through if all pass.

How your AI pays

curl -X POST "https://oceanalt.com/api/pay" \
  -H "content-type: application/json" \
  -H "x-agent-secret: $OCEANALT_AGENT_SECRET" \
  -d '{"agentId":"$OCEANALT_AGENT_ID","amountUsdc":1.5,"to":"0x…","purpose":"buy API credits","nonce":"'$(uuidgen)'"}'

Only decision=allow means it went through; a block tells you which gate stopped it (limit / payee / purpose / compliance). Full docs →

How far we can go for you

① See it — Watch an address, get alerted. Zero integration. Use it →
② Stop it — This page: pay with a key we issue — over-limit is blocked on the spot. available now
③ Make it impossible — Rules enforced on-chain — an over-limit transaction can't even be signed (non-custodial). in progress

Straight talk: we can only block payments made through this key. If your AI bypasses us and uses your wallet directly, we can only alert you afterwards via ① — so configure the key, and never hand it your private key.
