INFRASTRUCTURE FOR AUTONOMOUS AI AGENTS

Micropayments for the
Machine Economy™

AI agents can't access blockchain data without human-managed API keys.
We solved this with autonomous micropayments.

No API keys • No subscriptions • No human intervention
$0.0001 per RPC call • Solana, Ethereum, Base

The Problem with Traditional RPC

Traditional RPC

  • Requires human to sign up
  • Manage API keys manually
  • Monthly subscription fees
  • Vendor lock-in
  • Single point of failure
  • Can't automate for AI agents

x402 RPC Aggregator

  • Fully autonomous - No human needed
  • Micropayments - Pay per call ($0.0001+)
  • Pay only for what you use
  • Multi-provider - 8+ with auto-failover
  • 99.9% uptime - Intelligent routing
  • AI agent ready - Built for autonomy

Built for Autonomous Systems

Real-world use cases where AI agents need blockchain data without human intervention

DeFi Trading Bots

Autonomous bots need real-time price data, pool reserves, and transaction status. Pay $0.0001 per query, no human setup.

  • Real-time price feeds
  • Pool reserve tracking
  • Transaction monitoring

1M calls/month = $80-100 (vs $200-500 traditional)

NFT Analytics Agents

Scan collections, track floor prices, analyze metadata. Agents pay per query, scale automatically.

  • Collection scanning
  • Floor price tracking
  • Metadata analysis

100K calls/month = $8-10 (pay-per-use only)

Cross-Chain Indexers

Query Solana, Ethereum, and Base with one API. Intelligent routing ensures best provider for each chain.

  • Multi-chain support
  • Automatic failover
  • Optimized routing

Unified API across all chains

30-second flow: Discover → Pay → Get Data

$ curl -X POST https://x402labs.cloud/rpc \
-d '{"method":"getSlot","chain":"solana"}'
{
"invoice": {
"amount": 0.0001,
"provider": "Triton One",
"network": "solana-mainnet"
}
}
✓ Agent pays $0.0001 autonomously → RPC call executed
