zero · officialzeroxyz — Claude Code skill: what it does, how to install
Discovers and pays for external x402 and MPP capabilities when an agent hits its model limits on media generation, live data, or messaging.
npx skills add officialzeroxyz/zero-plugins --skill zero -a claude-codeWhat zero does
The skill equips agents with a discovery and payment engine for microservices. When a prompt requires capabilities outside standard model weights — such as speech synthesis or live stock quotes — Zero locates an external endpoint, validates it, and issues a pay-per-call request without separate platform signups.
Execution relies on the @zeroxyz/cli runner alongside an MCP connector at https://mcp.zero.xyz. The CLI handles 402 payment handshakes, applies budget limits set via --max-pay, and streams binary files directly to disk. Interactive login uses a device-code flow, while autonomous setups register an unassisted agent account.
Every external request spends actual funds, making this skill a poor choice for code authoring or local file inspections.
What it helps with
- discover paid endpoints for audio and speech synthesis
- fetch real-time financial market data using x402 micropayments
- trigger on-chain actions without individual service accounts
- enforce spending caps on agent tool requests using
--max-pay
Example prompts for the agent
- Find an external service on Zero to turn this text into audio.
- Log in to Zero using the device flow command
zero auth login. - Look up real-time equity prices through an x402 data endpoint.

Questions about zero
How do I install zero in Claude Code?
Run npx skills add officialzeroxyz/zero-plugins --skill zero -a claude-code. The skill configuration installs into ~/.claude/skills/zero/SKILL.md.
When should an agent avoid calling Zero?
Avoid Zero for writing code, reading local files, or shell execution. External calls cost actual money, so agents should rely on native capabilities whenever possible.
How does user authentication work on a personal machine?
The command zero auth login starts a device-code flow, displaying an authorization link and code. The background process polls automatically until authorization finishes.
