Exa: search API for agents
Give an agent live web context with POST https://api.exa.ai/search, or point MCP at mcp.exa.ai/mcp.
devrels.xyz/a/277Exa is a search API over Exa's own web index. You send a natural language query, you get ranked pages plus optional highlights. Site: exa.ai. Docs: exa.ai/docs.
Get a key at dashboard.exa.ai/api-keys. New accounts start with credits, no card required. If you only need Google-style SERP JSON, this is a different product: Exa ranks for agents, not for a browser results page.
Call search first
Default type is auto (~1s). Other types: fast, instant, deep, deep-lite, deep-reasoning. Optional category values include company, people, news. Coding agents should also read the coding-agent search reference.

Bring the product you already build. Cofounder runs the rest of the company as tasks you can approve.
Give an agent its own mailbox and delegated spend so verify → pay → receipt stays in one identity.
OpenAPI-built trading tools were not enough. Agents still needed the prose: which operation, which constraints, which auth. Alpaca put that behind MCP too.
