Hey HN!

We've built an API that lets developers issue purpose-built virtual cards for AI agents – no more duct-taping payment processors with manual approval workflows.

*The Problem* AI agents need to spend money autonomously, but current solutions force you to: - Share credit cards with dangerous open-ended access - Build clunky approval systems - Trust that "only buy cloud credits" won't be interpreted as "book a luxury cloud conference"

*How Ledger Works* 1. *Issue Cards Programmatically*: Create virtual cards for specific agents/tasks with one API call ``` card = ledger.Card.create( spend_limit="$800/day", merchant_lock="only_amazon_aws", expiry="single_use" ) ```

2. *Let Agents Transact*: Cards work at 9M+ merchants – but only within their programmed limits

3. *Monitor Everything*: Every transaction maps to specific agent/task pairs

*Why Devs Love It* - *Zero Trust by Design*: Cards auto-expire or scope to specific vendors/amounts - *Auto reconciliation*: Each card ties directly to an agent's spend logs - *True Automation*: From DevOps bots provisioning cloud resources to shopping agents making verified purchases

Building AI agents? We'd love to hear how you're thinking about handling payments.
