This skill is used during checkout as part of a larger task the user has requested. ### Setup A Halocard token is required. If not configured: Ask the user to sign up: https://secure.halocard.co/enter Ask the user to copy paste an API token: https://secure.halocard.co/dashboard Store it as HALOCARD_TOKEN environment variable ### When This Skill Activates This is a payment step, not a standalone task. It activates when: You're executing a task that requires an online purchase (ordering food, buying a product, subscribing to a service, etc.) You've reached the checkout/payment page and need a card to complete it ### 1. Navigate to checkout Complete the shopping/ordering flow as part of the user's task. Proceed until you reach the payment page. ### 2. Read the total from the page Extract the exact total amount from the checkout page. Do not guess or estimate. ### 3. Confirm with the user before proceeding Always present the following to the user and wait for explicit approval before creating a card: Merchant/website Items being purchased (brief summary) Total amount Example: 💳 Ready to pay. Uber Eats — 2x chicken shawarma, 1x hummus. Total: £24.50. Go ahead? Do not create a card until the user confirms. ### 4. Build the description from context Construct a clear description from what you know: The merchant/website name What's being purchased Example: "Uber Eats order - 2x chicken shawarma, 1x hummus" ### 5. Create the card POST https://agent.halocard.co/api/v1/payments Headers: Authorization: Bearer $HALOCARD_TOKEN, Content-Type: application/json { "amount": 2450, "description": "Uber Eats order - 2x chicken shawarma, 1x hummus" } amount: integer in cents ($24.50 → 2450). Match the checkout total exactly. description: what's being purchased + merchant Response: { "data": { "card": { "id": "card_abc123", "pan": "4111111111111111", "cvc": "123", "expiryMonth": "03", "expiryYear": "2027" } } } ### 6. Fill the payment form Enter the card details into the checkout form: Card number → pan CVC/CVV → cvc Expiry month → expiryMonth Expiry year → expiryYear Cardholder name → user's name (ask if unknown) Billing address → user's address (ask if unknown) ### 7. Submit and confirm Submit the payment. Verify the order confirmation page loaded. Report the outcome to the user. ### Spending Limits If the user set a max amount for the task (e.g. "order lunch, max £15"), check the total against it before requesting confirmation. If over budget, inform the user. Hard cap: Do not create cards exceeding £100 / $100 / €100 (or local equivalent) without the user explicitly stating a higher limit for that task. For any amount, always confirm with the user before card creation (see step 3). ### Rules Never log or store card details (PAN, CVC) to any file. Match the amount exactly to the checkout total — read it from the page. Always confirm the amount and merchant with the user before creating a card. No exceptions. Create the card only when ready to fill the payment form — cards are single-use. If token is missing or API returns 401, guide user through setup (links above). If payment fails, report the error to the user. Do not retry with a new card without asking. ### Example (curl) curl -X POST https://agent.halocard.co/api/v1/payments \\ -H "Authorization: Bearer $HALOCARD_TOKEN" \\ -H "Content-Type: application/json" \\ -d '{"amount": 2450, "description": "Uber Eats order - 2x chicken shawarma"}' ## Trust - Source: tencent - Verification: Indexed source record - Publisher: adhambadr - Version: 1.0.2 ## Source health - Status: healthy - Item download looks usable. - Yavira can redirect you to the upstream package for this item. - Health scope: item - Reason: direct_download_ok - Checked at: 2026-04-29T20:10:40.559Z - Expires at: 2026-05-06T20:10:40.559Z - Recommended action: Download for OpenClaw ## Links - [Detail page](https://openagent3.xyz/skills/halocard-virtualcards) - [Send to Agent page](https://openagent3.xyz/skills/halocard-virtualcards/agent) - [JSON manifest](https://openagent3.xyz/skills/halocard-virtualcards/agent.json) - [Markdown brief](https://openagent3.xyz/skills/halocard-virtualcards/agent.md) - [Download page](https://openagent3.xyz/downloads/halocard-virtualcards)
