Use PZERO in Cursor
Two ways in: hosted MCP (recommended), or Cursor's OpenAI-compatible HTTP settings. Same prepaid balance and same pzero_… key either way.
Fund first
You need a key and confirmed USDC balance before Cursor can spend. Pending credit is not spendable.
- Top Up with x402 for the agent HTTP signup / refill path
- Mint an API Key in Studio if you prefer signing in and minting in the app
Connect via MCP
Paste the Cursor config, put your Bearer key in place, reload MCP, then ask the agent to call agent_me.
Paste into Cursor MCP settings, reload MCP, then ask your agent to call agent_me.

Connect via the API
Skip MCP if you prefer Cursor custom models on the OpenAI-compatible HTTP path.
Open Settings → Models
Turn on OpenAI API Key and paste your pzero_… key. Turn on Override OpenAI Base URL and set https://api.pzero.studio/v1. Both toggles must be on.
- Add a pzero/ model
Cursor rejects ids that match its built-ins. Add Custom Model as pzero/<model-id>, for example pzero/claude-opus-4-8. Use live text ids from GET /v1/models. Image and video models are not callable via chat. Cursor BYOK posts chat completions to this same /v1 base URL; no /cursor suffix.
Select it in Agent
Pick a pzero/… model in Agent. Composer-branded models typically ignore a custom OpenAI key. Turn the OpenAI API Key toggle off when you want Cursor's native stack again (key and base URL stay saved).
