PayPilot — Payment Processing for AI Agents
Accept payments, send invoices, issue refunds, and track sales — all through conversation.
Setup
PayPilot connects to a hosted API proxy at https://paypilot.agms.com. On first use, check for credentials:
cat ~/.config/paypilot/config.json
If no config exists, guide the user through setup:
- Register on the PayPilot proxy:
curl -s "https://paypilot.agms.com/v1/auth/register" -X POST \
-H "Content-Type: application/json" \
-d '{"name":"BUSINESS_NAME","email":"EMAIL","password":"PASSWORD"}'
- Login to get an access token:
curl -s "https://paypilot.agms.com/v1/auth/login" -X POST \
-H "Content-Type: application/json" \
-d '{"email":"EMAIL","password":"PASSWORD"}'
- Configure the payment gateway key:
curl -s "https://paypilot.agms.com/v1/auth/configure" -X POST \
-H "Content-Type: application/json" \
-H "Authorization: Bearer $TOKEN" \
-d '{"gateway_key":"YOUR_GATEWAY_KEY"}'
- Save credentials locally:
mkdir -p ~/.config/paypilot
cat > ~/.config/paypilot/config.json << 'EOF'
{
"api_url": "https://paypilot.agms.com",
"email": "merchant@example.com",
"token": "jwt_token_here"
}
EOF
chmod 600 ~/.config/paypilot/config.json
Note: The password is used only during registration and login to obtain a JWT. It is never stored in the config file or read from environment variables.
If the user doesn't have a gateway account, start the onboarding process:
-
Collect basic info conversationally:
- Business name
- Contact name
- Phone
- Business type (retail, restaurant, ecommerce, mobile, etc.)
-
Save the lead to our system:
curl -s "https://paypilot.agms.com/v1/onboard" -X POST \
-H "Content-Type: application/json" \
-d '{"business_name":"Acme Corp","contact_name":"John Doe","email":"john@acme.com","phone":"555-1234","business_type":"retail"}'
- Send them the full application link to complete and e-sign:
"Great! To finish your application, complete the form here: https://agms.com/get-started/ It takes about 5-10 minutes. You'll need your business address, Tax ID, and banking info. After you submit, you'll e-sign right away and typically get approved within 24-48 hours. Once approved, come back and I'll set up your payment processing in seconds."
Important: The agent NEVER collects SSN, Tax ID, bank account/routing numbers, or other sensitive PII. Those go through the secure AGMS form only.
Authentication
All payment endpoints require a JWT bearer token. Load config and set headers:
CONFIG=$(cat ~/.config/paypilot/config.json)
API=$(echo $CONFIG | jq -r '.api_url')
TOKEN=$(echo $CONFIG | jq -r '.token')
AUTH="Authorization: Bearer $TOKEN"
If a request returns 401, re-login and update the saved token.
To refresh an expired token: Prompt the user for their password — never store it or read it from environment variables:
# Re-login
LOGIN=$(curl -s "$API/v1/auth/login" -X POST \
-H "Content-Type: application/json" \
-d "{\"email\":\"$(echo $CONFIG | jq -r '.email')\",\"password\":\"$USER_PASSWORD\"}")
NEW_TOKEN=$(echo $LOGIN | jq -r '.access_token')
# Update config
TMP=$(mktemp)
chmod 600 "$TMP"
jq --arg t "$NEW_TOKEN" '.token = $t' ~/.config/paypilot/config.json > "$TMP" && mv "$TMP" ~/.config/paypilot/config.json
chmod 600 ~/.config/paypilot/config.json
Core Commands
Charge / Sale
Process a payment using a vaulted card token. Never handle raw card numbers.
curl -s "$API/v1/payments/charge" -X POST \
-H "Content-Type: application/json" -H "$AUTH" \
-d '{"amount":500.00,"token":"VAULT_ID","description":"Consulting — January"}'
Enable 3D Secure for higher-value or flagged transactions:
curl -s "$API/v1/payments/charge" -X POST \
-H "Content-Type: application/json" -H "$AUTH" \
-d '{"amount":2500.00,"token":"VAULT_ID","description":"Premium service","three_d_secure":true}'
The response includes risk assessment and verification:
{
"transaction_id": "123",
"status": "complete",
"amount": 2500,
"risk": { "score": "low", "flags": [] },
"verification": { "avs": "Y", "cvv": "M" },
"three_d_secure": true
}
Send Invoice / Payment Link
curl -s "$API/v1/payments/invoice" -X POST \
-H "Content-Type: application/json" -H "$AUTH" \
-d '{"amount":500.00,"email":"john@example.com","description":"Consulting — January"}'
Refund
# Full refund
curl -s "$API/v1/payments/refund" -X POST \
-H "Content-Type: application/json" -H "$AUTH" \
-d '{"transaction_id":"TXN_ID"}'
# Partial refund
curl -s "$API/v1/payments/refund" -X POST \
-H "Content-Type: application/json" -H "$AUTH" \
-d '{"transaction_id":"TXN_ID","amount":50.00}'
Void (same-day cancel)
curl -s "$API/v1/payments/void" -X POST \
-H "Content-Type: application/json" -H "$AUTH" \
-d '{"transaction_id":"TXN_ID"}'
View Transactions
curl -s "$API/v1/transactions" -H "$AUTH" | jq .
Sales Summary
curl -s "$API/v1/transactions/summary" -H "$AUTH" | jq .
Customer Vault (Tokenize Cards Securely)
Store a card securely — returns a vault token. The customer enters card details through a secure form; raw card data never touches the agent.
curl -s "$API/v1/vault/add" -X POST \
-H "Content-Type: application/json" -H "$AUTH" \
-d '{"first_name":"John","last_name":"Smith","email":"john@example.com"}'
Charge a Vaulted Card
curl -s "$API/v1/vault/charge" -X POST \
-H "Content-Type: application/json" -H "$AUTH" \
-d '{"vault_id":"VAULT_ID","amount":99.00,"description":"Monthly service"}'
Recurring Billing
# Create subscription
curl -s "$API/v1/subscriptions" -X POST \
-H "Content-Type: application/json" -H "$AUTH" \
-d '{"vault_id":"VAULT_ID","plan_id":"monthly_99","amount":99.00,"interval":"monthly"}'
# Cancel subscription
curl -s "$API/v1/subscriptions/SUB_ID" -X DELETE -H "$AUTH"
Fraud Detection & Rules
# View 30-day fraud analytics
curl -s "$API/v1/fraud/summary" -H "$AUTH" | jq .
# List active fraud rules
curl -s "$API/v1/fraud/rules" -H "$AUTH" | jq .
# Create a fraud rule (flag transactions over $5000)
curl -s "$API/v1/fraud/rules" -X POST \
-H "Content-Type: application/json" -H "$AUTH" \
-d '{"rule_type":"max_amount","threshold":"5000","action":"flag"}'
# Supported rule types: max_amount, min_amount, velocity_limit
# Actions: flag (alert), block (reject), review (hold)
# View a specific rule (if supported)
curl -s "$API/v1/fraud/rules/RULE_ID" -H "$AUTH" | jq .
# Delete a rule
curl -s "$API/v1/fraud/rules/RULE_ID" -X DELETE -H "$AUTH"
Note: rule updates are not supported. Delete and recreate the rule instead.
Example response from creating a rule:
{
"rule_id": "rule_123",
"rule_type": "max_amount",
"threshold": "5000",
"action": "flag",
"status": "active",
"created_at": "2026-03-15T00:00:00Z"
}
When reporting fraud stats:
"🛡️ Last 30 days: 45 transactions, 0 flagged, 0 blocked. 1 active rule (max $5,000). Fraud rate: 0.00%"
Security Rules
- NEVER ask for, log, or store raw credit card numbers
- NEVER include card numbers in conversation history or memory files
- ALWAYS use payment links or customer vault tokens for charges
- ALWAYS use HTTPS — the proxy enforces TLS
- API tokens and gateway keys must stay in config files, never in chat
- The proxy encrypts gateway keys at rest (AES-256-GCM)
- Rate limited: 60 requests/min global, 5/min on auth endpoints
Error Handling
- 401 Unauthorized: re-login, update the saved token, then retry.
- 400 Bad Request: validate request body and log the error message.
- 429 Rate Limited: 60 req/min global, 5/min auth. Back off and retry.
- 5xx Server Error: retry with exponential backoff.
- Network errors: verify HTTPS connectivity, then retry.
Response Patterns
When a payment succeeds:
"✅ Payment of $500.00 processed. Transaction ID: abc123."
When sending an invoice:
"📧 Payment link for $500.00 sent to john@example.com."
When a payment fails:
"❌ Payment declined. Want to try a different method or send a payment link instead?"
When checking sales:
"📊 This month: 23 transactions · $4,750 in sales · 2 refunds ($150) · Net: $4,600"
