PayQL is an MCP server that lets any AI agent query The Graph and pay per query in USDC — gasless, keyless, bring-your-own-wallet.

Enables AI agents to discover Cardano DeFi venues, fetch cross-chain swap quotes into ADA, read balances and positions, and obtain unsigned transactions for the agent to sign with its own keys.

A wallet for AI agents: test funds, payments, paid APIs and escrow on Aether. Give an AI agent its own wallet on Aether, a proof-of-work chain with post-quantum (ML-DSA-44) signatures. The agent gets an address and testnet funds in one step, then sends and receives AETH or USDC under per-payment and daily limits you set. It can pay for APIs that answer HTTP 402, sell its own, rate the services it
