AI-Native Alternatives to Paddle for Agent Payments

B2B SaaS billing assumes invoices and seats. Agent commerce is metered, instant and machine-to-machine.

Why Paddle doesn\u2019t fit agent payments

Paddle’s merchant-of-record model targets B2B SaaS: seats, invoices, sales-tax handling, human procurement. Agent customers do not procure — they call. A billing flow that starts with "talk to sales" or even "enter company details" filters out every machine buyer, and subscription tiers waste the per-request granularity agents actually consume.

The alternative stack treats payment as part of the API protocol: the server states a price (HTTP 402), the agent pays it, access is granted immediately. Billing, metering and settlement collapse into one step — implemented by the open-source projects below.

What to look for instead

  • Self-serve machine onboarding — no sales flow, no checkout
  • True usage metering (per request / per token / per call)
  • Instant access after payment, in the same session
  • Open protocols your agent customers can discover and integrate

Frequently asked questions

Can Paddle bill AI agents for API usage?

Paddle can meter and invoice usage, but the flow still assumes human buyers with accounts. Agent-native rails settle each request in real time with no account provisioning — the projects below implement that.
