Stripe charges $0.30 + 2.9% per transaction — a floor that makes $0.01–$0.05 agent microtransactions structurally unprofitable. API providers are forced into subscriptions and prepaid credits, neither of which works for autonomous agents that need to pay as they go, at machine speed, without human approval.

$0.0001/tx·Native USDC·No gas auctions·No EVM

Stellar's Consensus Protocol settles at $0.0001 per transaction with native USDC support — the optimal rail for high-frequency, low-value workloads that define agent traffic. Predictable, near-zero fees at any volume.

One middleware. That's it.
