# PayAI x402 Facilitator pricing

You are billed per **settlement** — the on-chain movement of funds. `POST /verify`, `GET /supported`, and the `/discovery/*` endpoints are free and unauthenticated.

| Plan | Price | Settlements included |
| --- | --- | --- |
| Free Forever | $0 | Capped by total settlements. Exceeding it returns HTTP 403 with an `errorReason` beginning `free_tier_exhausted`. |
| Pay As You Go | $0.001 per settlement | Unlimited |
| Enterprise | Contact for pricing | Unlimited, with dedicated settlement lanes |

On Solana the facilitator sponsors the network fee, so a payer needs only USDC and no SOL. Gas on EVM networks is likewise covered by the facilitator.

Credits, usage, and auto top-up are managed at https://merchant.payai.network. Enterprise enquiries: info@payai.network.

Request-rate limits are separate from pricing and are documented at https://facilitator.payai.network/developers#api-rate-limits.
