## What it 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.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add officialzeroxyz/zero-plugins --skill zero -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/zero/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/zero/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add officialzeroxyz/zero-plugins --skill zero -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/zero/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add officialzeroxyz/zero-plugins --skill zero -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/zero/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install officialzeroxyz/zero-plugins zero
```

2. **Manually: put the files in place**
- File: `.github/skills/zero/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add officialzeroxyz/zero-plugins --skill zero -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/officialzeroxyz/zero-plugins --path plugins/zero/skills/zero
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/zero/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add officialzeroxyz/zero-plugins --skill zero -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/officialzeroxyz/zero-plugins/tree/HEAD/plugins/zero/skills/zero/SKILL.md

## When to use it
- 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
- 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.
