Endpoint chi la nen tang; cac pattern moi la nhung gi cac builder cua agent thuc su trien khai.
Agents that decide what to buy and execute the purchase without human approval. The API issues a fresh card per transaction, charges it, then deletes it — leaving no reusable payment surface in the wild.
Programmatic issuance of one BIN-471938 (Visa Business) card per Meta / Google / TikTok ad account. Rotate cards every 30-60 days to keep accounts clean.
Marketplaces or platforms that need a unique card per end-user transaction. Issue, charge, delete in under 10 seconds — no PCI scope, no card-storage burden.
Sign up to free trials at scale. Each trial gets a card with the minimum load; deletion before renewal blocks the auto-charge cleanly.
Multi-tenant agents that bill upstream SaaS (AWS, OpenAI, Cloudflare, GitHub) on a per-workspace card. Costs become attributable to the customer without leaking your master billing identity.
Each worker requests a card via the API the moment it needs a payment surface, uses it for the intended action, then closes it. The $1.50 unit cost is a fraction of any alternative approach.
