Agent One Key

Set up with Skill

Give a coding agent (Claude Code, Cursor) the served Agent Key skill so it can discover, inspect, and run resources on its own.

The Agent Key skill is a single served file that teaches an agent how to use Agent One Key — how to discover, inspect, estimate, run, and settle resources — without you wiring each endpoint by hand. It's the fastest path for a coding agent like Claude Code or Cursor.

The served skill

The skill is served at:

https://api.deva.me/v1/agents/SKILL.md

(The dashboard also links a hosted copy at https://www.deva.me/skill.md.) Add it to your agent's skills or system instructions so the agent knows the full resource rail, then give the agent a key to authenticate with:

export DEVA_API_KEY="deva_..."

Need a key first? → Create, reveal & copy a key. The agent's spend stays bounded by that key's spend caps.

When to use this

  • Skill — a coding agent that calls the HTTP API directly and benefits from built-in guidance.
  • MCP — a hosted tool interface for MCP clients (Claude, Codex, Cursor).
  • API — you're writing the integration yourself.
