MARKETPLACE
Service Marketplace
Data APIs and secure runtime tools for AI agents. Pay per request with USDC via x402. No API keys, no subscriptions.
How It Works
Send a request
Call any marketplace endpoint. If no payment is attached, you get a 402 response with the exact price.
Pay with USDC
Attach an x402 payment header with the quoted amount. Payment goes directly to the service partner treasury.
Get your result
Receive the response from the provider. Transaction receipt included in response headers.
Available Services
One endpoint, 40+ chains — JSON-RPC, no API key
Standard JSON-RPC 2.0 across 40+ chains (Ethereum, Base, Solana, Polygon, BSC, Arbitrum, Optimism, Avalanche, Bitcoin, and more) through a single endpoint — just swap the chain in the path: POST /v1/rpc/{network}. EVM eth_* methods and non-EVM (Solana getSlot, …) both work. Pay-per-call in USDC via x402 — no API keys, no rate-limit tiers. Powered by Tatum.
