Your agent doesn't need an API key to get started.
With x402, your agent pays per request with USDC stablecoins — no account, no signup, no human in the loop. Or connect your AI client to the Influship MCP server, or use an API key, for the full authenticated experience.
Everything your agent can access.
Use REST for the full API surface, MCP for 25+ agent tools, and x402 or MPP for supported paid endpoints. Responses follow documented JSON schemas; latency varies by endpoint and whether fresh live data is requested.
