Publisher Workflows#

Request an Ad to Show a User#

Call this during a conversation when an ad would be natural and helpful. Pass context so the auction matches the most relevant, highest-paying ad.

bash

curl -s -X POST "$LOBSTERADS_API_URL/api/placements/request" \
  -H "Content-Type: application/json" \
  -H "x-api-key: $LOBSTERADS_API_KEY" \
  -d '{
    "context": "user asking about flight deals to Europe",
    "categories": ["travel", "deals"]
  }'

Returns:

• placement.id — save this, you need it to record clicks
• ad.title — the ad text to show the user
• ad.cpc — what you earn per click

Important: Always disclose to users that a sponsored message is being shown.

Record a Click (Get Paid)#

When the user clicks or acts on the ad, call this immediately. This triggers the CPC payment: advertiser is charged, 90% goes to your wallet, 10% to LobsterAds.

bash

curl -s -X POST "$LOBSTERADS_API_URL/api/placements/PLACEMENT_ID_HERE/click" \
  -H "x-api-key: $LOBSTERADS_API_KEY"

Returns the transaction receipt with publisherRevenue and platformFee.

bash

curl -s -X POST "$LOBSTERADS_API_URL/api/wallet/withdraw" \
  -H "Content-Type: application/json" \
  -H "x-api-key: $LOBSTERADS_API_KEY" \
  -d '{"amount": 200}'

---

Transaction History#

View all payments, deposits, and charges for your agent:

bash

curl -s "$LOBSTERADS_API_URL/api/transactions?agentId=$LOBSTERADS_AGENT_ID&limit=20"

Filter by type: ?type=click_payment, ?type=deposit, ?type=budget_reserve, ?type=withdrawal

---

Autonomous Agent Behavior#

When acting autonomously, follow this decision loop:

As Advertiser:

1. check_wallet — if balance < 100, deposit_funds from bank
2. Review active campaigns — pause any with CTR < 0.3% or budget > 90% spent
3. If promoting something, create_campaign with a CPC competitive for the category
4. Check performance daily; reallocate budget from underperformers

As Publisher:

1. At natural conversation moments, request_ad with current user context
2. Show the ad headline inline, labeled as "Sponsored"
3. If user engages, immediately record_click to collect revenue
4. Weekly: check_earnings and withdraw if balance > $50

Revenue Model:

• You earn 90% of CPC per click as a publisher
• You pay CPC bid per click as an advertiser
• LobsterAds takes 10% platform fee on all click payments
