Pricing — Usage-Based Agent Payment Fees

No monthly fees.
Pay per transaction.

Pægents charges only for what you use. No seat licenses, no platform minimums, no overage penalties. Full infrastructure — policy enforcement, escrow, receipts, webhooks — included on every plan.

Fee Schedule

Current pricing across the supported payment rails. All fees are assessed by Pægents on top of any underlying payment processor fees.

Payment Rail	Fee	Minimum Agreement	Min Fee	Settlement
Bilateral Escrow USDC · Base	$0.10 USDC setup + $0.003 per call	$0.30 USDC	$0.10	Automatic on-chain · 24h challenge window
Stablecoin Direct x402 · USDC	2% + $0.05	$5.00	$0.15	Instant on-chain settlement
Card Stripe Connect	1% platform fee + Stripe processing	$5.00	$0.05	Standard Stripe payout schedule

Stripe processing fees apply on the card rail (typically 2.9% + $0.30 per transaction). These are assessed by Stripe, not Pægents, and are passed through to the seller's connected account.

How Each Rail Works

Bilateral Escrow

USDC is locked in the MeteringEscrow smart contract on Base before any service calls execute. The buyer prepays, the seller is guaranteed funds exist, and both parties can verify escrow state on-chain at any time.

Settlement is automatic: when an agreement completes, the platform submits a signed cumulative receipt, initiates a 24-hour challenge window, then finalizes on-chain. Seller claims via their own wallet — Pægents never moves funds.

$0.10 setup + $0.003 / call

Stablecoin Direct (x402)

Per-request USDC payments using the HTTP 402 Payment Required protocol on Base. No escrow, no agreements — each API call carries its own payment authorization and settles immediately on-chain.

Best for low-latency, high-frequency workloads where per-call payment overhead is acceptable and agreement setup cost should be avoided.

2% + $0.05 / transaction

Card (Stripe Connect)

Card-based payments via Stripe Connect, suited for buyers who prefer traditional payment methods or operate in contexts where stablecoin flows aren't practical.

Sellers onboard as Stripe Connect accounts. Pægents applies a 1% platform fee on top of standard Stripe processing. Payouts follow Stripe's standard schedule.

Common Questions

Is there a free tier or trial?

Yes. Account creation and agent registration are free. You only incur fees when transactions execute. You can fully validate the escrow flow on Base Sepolia testnet using faucet USDC before committing real funds.

Are there monthly or seat-based fees?

No. Pægents charges no monthly platform fees, no per-seat costs, and no minimum commitments. You pay only for transactions you actually process.

What happens to escrow funds if an agreement fails?

If a circuit breaker fires or an agreement expires, the platform initiates settlement immediately. The seller is paid for calls already completed; the buyer's remaining balance is returned. Settlement is on-chain and non-custodial — Pægents never holds the funds.

Do Pægents fees apply to testnet transactions?

No. Testnet transactions on Base Sepolia use faucet USDC and do not incur any Pægents fees. Testnet is a full-fidelity validation environment at zero cost.

How is the bilateral escrow setup fee charged?

The $0.10 USDC setup fee is collected from the buyer's escrow deposit at agreement activation, before service calls begin. It covers on-chain contract initialization and receipt signer registration.

What about volume pricing or enterprise plans?

High-volume deployments and enterprise customers with custom requirements can discuss negotiated pricing. Contact us to start that conversation.

Who pays the fees — buyer or seller?

On the escrow rail, the buyer pays the setup fee and per-call fees as part of the funded escrow. On the Stripe card rail, the Stripe processing fee is deducted from the seller's payout and the 1% Pægents fee is assessed on the transaction amount. On x402, fees are deducted from the payment amount.

Is there an SDK or API I can use to estimate costs?

The escrow fee structure is deterministic: multiply expected call volume by $0.003 and add the $0.10 activation fee. For card and x402 rails, apply the percentage and flat fee to the transaction amount. The Python and TypeScript SDKs expose agreement metadata including fee breakdowns.
