Solvador is a multi-chain x402 payment facilitator that lets AI agents and API developers pay for services with stablecoins across 15+ blockchain networks.
We support three x402 payment schemes - exact, upto, and batch-settlement - giving developers flexible options for per-request payments, metered usage, and cost-efficient settlement at scale.
Whether you're building autonomous agents that need to pay for APIs or monetizing an API for machine customers, Solvador provides the settlement infrastructure to make it work on whichever chain you choose.
Clients hold stablecoins on different networks and supporting each chain separately is a heavy lift. Solvador gives you a single facilitator integration that accepts payments across 15+ networks. Your clients can pay on whichever chain they prefer and you serve them all without extra work.
Autonomous AI agents need to pay for APIs, data feeds, and compute without human intervention or credit cards. With Solvador, agents pay per request in stablecoins using the x402 protocol. No API keys to manage, no subscriptions to set up, no invoices. The agent sends a payment with the request and gets the resource back instantly.
API developers can monetize their endpoints without building billing infrastructure. Add a single middleware, set your price, and start accepting stablecoin payments from any client on 15+ networks. No user accounts, no payment provider onboarding, no chargebacks. Solvador handles verification and settlement so you can focus on your product.
With the upto scheme, clients authorize a maximum amount and only pay for what they actually consume. This fits LLM inference, streaming data, and any service where the final cost is unknown upfront. The client stays in control of the spending cap while the server settles the exact usage.
Per-request onchain settlement gets expensive at scale. The batch-settlement scheme aggregates many small payments and settles them together, cutting gas costs dramatically. This makes sub-cent pricing viable for high-frequency use cases like per-token inference pricing or per-call data lookups.
