Cortex402
- Ooak21/cortex402
cortex402 is an MCP server that signs USDC x402 payments on Base for per-call sanctions, aviation weather, and US property data.
About
cortex402 MCP bridges coding agents to pay-per-use data products on Base using the x402 payment pattern. developers building compliance tooling, logistics features, or property research apps can fund a small USDC balance (~$5 covers on the order of tens of calls per README guidance) and let the agent invoke sanctions, aviation weather, or US property endpoints without negotiating enterprise data contracts. Each call signs payment from your EVM wallet; ceilings are configurable via CORTEX402_MAX_PAYMENT_USDC. Treat it as a metered integration: ideal for prototypes and selective production enrichment, not for high-volume batch ETL unless you model cost explicitly.

What it does
Pay per API call with USDC on Base so your agent can pull sanctions, aviation weather, or US property data without a traditional SaaS subscription.
Who is it for?
Best when you're prototyping compliance, aviation, or real-estate features and accept crypto micropayments on Base mainnet.
Skip if: Skip if you cannot use private keys in dev environments, need flat-rate enterprise data contracts, or want free public-only datasets only.
What you get
After configuring a funded Base USDC wallet, your agent can fetch paid Cortex402 data products with automatic per-call authorization.
- Agent-callable sanctions, aviation weather, and US property data responses
- Per-call signed USDC payments within configured max ceiling

FAQ
Who is cortex402 for?
Developers and agent developers who need sanctions, aviation weather, or US property data via x402 USDC payments on Base.
When should I use cortex402?
Use it during Build integrations when your feature needs live paid data and you want the agent to call Cortex402 without custom payment code each time.
How do I add cortex402 to my agent?
Install npm cortex402-mcp 0.2.0, set CORTEX402_WALLET_PRIVATE_KEY for a Base USDC wallet, optionally tune CORTEX402_MAX_PAYMENT_USDC, and register the stdio server in your MCP config.
