Cohesive payment infrastructure,
for every agent.
The unified payment infrastructure for AI agents. A single API supporting both x402 and MPP, with every transaction settled on Solana and every agent provisioned with a programmable wallet and configurable spend controls.

Trusted by teams building the next generation of autonomous agents.
One API. Any protocol.
The agent payment landscape is fragmented across incompatible protocols, with no shared wallet primitive, no spend controls, and no verifiable on-chain record. Maxim Protocol resolves this at the infrastructure level.
Protocol agnostic
Supports x402 and MPP natively, with automatic protocol detection on every request. No conditional logic required in application code.
On-chain by default
Every transaction settles on Solana with a public signature. There is no secondary ledger or off-chain reconciliation layer.
Programmable spend controls
Per-agent budget caps, domain allowlists, rate limits, and call-level ceilings are enforced at the gateway before any funds move.
Agent wallets, out of the box.
Every agent provisioned through Maxim Protocol is assigned a Solana wallet on first initialization. Fund it, query the balance, and settle payments through a single consistent API, with no separate key management infrastructure required.
- Program Derived Addresses on Solana
- USDC settlement by default
- Fund via dashboard or on-chain transfer
- Non-custodial by design
One call. Any protocol.
A single call to maxim.pay() handles both x402 and MPP automatically. Protocol detection, session management, and signed payload construction are resolved at the gateway. Your application writes one line of code.
- Auto protocol detection
- x402 and MPP handlers
- Transaction hash on every response
- Session reuse for MPP
const response = await fetch( "https://api.maximprotocol.com/v1/pay", { method: "POST", headers: { "Authorization": `Bearer ${process.env.MAXIM_API_KEY}`, "Content-Type": "application/json", }, body: JSON.stringify({ agentId: "my-agent", endpoint: "https://api.dune.com/v1/query/1234/results", method: "GET", }), } ); const data = await response.json();
Every agent chain, on-chain.
When an orchestrator delegates work to sub-agents, the complete payment hierarchy is recorded on Solana with linked transaction references. Every spend is attributable, auditable, and queryable without a separate accounting layer.
- On-chain payment chains
- Budget caps per sub-agent invocation
- Queryable via API or Solana RPC
- Works with any agent framework
