# Criptonlabs Agent APIs

> Read-only XRP Ledger and Solana data for agents: XRPL fees, funded order books, slippage, AMM pools, account summaries and network health, and Solana transfer readiness, token and network health verdicts. Built for agentic payments: run pre-payment checks on fees, network health and account state before building a transaction. The A2A endpoint /a2a is free JSON-RPC: call SendMessage with a data part {skill, arguments}. The MCP endpoint /mcp/pro currently serves free data, the same as /mcp. Paid access via x402 is announced but not active.
