Complete payment infrastructure for autonomous AI agents. From cryptographic budget controls to instant settlement to agent-specific security - enabling agents to transact independently across multiple payment methods.
⚠️ Currently in BETA – Multi-chain crypto payments are live now. Additional payment methods coming soon. Contact us for custom integrations.
AI agents are getting smarter, but they still can't make payments autonomously. Traditional payment systems require human approval for every transaction, blocking the path to true agent-to-agent commerce.
Building payment flows for agents means handling wallets, budgets, and blockchain transactions from scratch. Too complex for most teams.
Traditional rate limiting and fraud detection don't work for agents. You need agent-specific security patterns.
Supporting crypto AND cards means integrating multiple payment providers with different APIs and workflows.
Agents don't view ads or convert like humans. You need direct payment mechanisms but they don't exist.
Traditional payment APIs don't support pre-authorized spending limits. Every transaction needs manual approval.
Setting up crypto wallets, payment verification, and webhook systems takes weeks. Most merchants never launch.
AgentGatePay provides the missing payment layer for the autonomous economy - a protocol-agnostic gateway router that works across payment methods, starting with multi-chain crypto and expanding to traditional rails.

Complete infrastructure stack for autonomous agent commerce
Universal payment routing layer supporting multiple payment methods through a single API. Crypto live today (USDC, USDT, DAI on 4 chains), credit cards and ACH coming Q1 2025. Modular design means adding new payment methods never breaks existing integrations.
Subscription-style spending authorization for agents - like SaaS subscriptions but for AI. Set budgets ($100), permission scopes (API access tiers), and custom duration (hours to months). Cryptographic Ed25519 signatures with real-time USD tracking. Enterprise-grade atomic operations prevent overdrafts even with concurrent requests.
The first security firewall built specifically for AI agents (not humans). Features 5-layer defense: distributed rate limiting, TX-hash replay protection, behavioral reputation scoring (0-200 scale), suspicious pattern detection, and schema validation. Automatically blocks agents with reputation scores below 30.
Native HTTP 402 "Payment Required" implementation with multi-chain blockchain settlement. Intelligent verification strategy: small payments settle instantly, larger payments receive extended verification for fraud prevention. Supports rapid settlement on fast chains (Base, Polygon, Arbitrum).
Immutable audit logging for every transaction, security event, and system action. Dual-write architecture with short-term queryable storage and permanent backup. Provides comprehensive logs and reports for payment verification, fraud analysis, and compliance auditing. Blockchain verification links and user-scoped access control with fast query performance.
From mandate to payment in 4 simple steps
Like a SaaS subscription for agents: set a budget ($100), duration (custom TTL), and permission scopes. Agent spends autonomously within these limits - no human approval for each transaction.
AP2 SaaS MandatesService replies with HTTP 402 + machine-readable payment requirements (chain, token, amount, recipient).
X402 ProtocolAgent pays stablecoins (USDC/USDT/DAI) on selected chain, gets a transaction hash as proof.
Multi-Chain SupportGateway verifies payment on-chain and returns the resource (200 OK). Budget updated, audit log created.
Instant VerificationBuilt for developers, merchants, and the entire autonomous economy
Autonomous purchasing power with cryptographic budget controls. Pay-per-use for APIs, data, and compute without human approval.
Simple SDK integration (Python, TypeScript). Production-ready examples for LangChain, n8n, and custom frameworks.
Accept agent payments with low fees. Instant settlement, no chargebacks, immutable audit trail for compliance.
Monetize your agent's services. Accept micropayments from other agents automatically with webhook notifications.
Enable business models impossible with traditional payments. Sub-dollar transactions with minimal overhead.
AIF firewall, behavioral reputation scoring, comprehensive audit logs. Built for production with immutable transaction records.
