ZER0

ZER0 (zero.xyz) is a search engine for AI agents, built to let autonomous coding agents and AI assistants discover and use thousands of external APIs and services on the fly — without managing accounts, API keys, or subscriptions. It installs via a single CLI command and works with a pay-per-call billing model funded through a crypto wallet (USDC on Base). The project describes itself as "a product of the people's internet experiment" and has a SOC 2 audit in progress.

What It Is

ZER0 is an agent-facing capability marketplace and discovery layer. Rather than requiring developers to pre-configure API credentials for every service an agent might need, ZER0 indexes API services across the internet so an agent can search, evaluate, and call them dynamically. The agent finds the right tool, makes the call, and the cost is settled per-use directly between the agent's wallet and the service provider. ZER0 itself does not custody, control, process, or distribute funds — it only facilitates discovery.

How the Workflow Works

The setup path is intentionally minimal:

• Install the CLI with one shell command (curl -fsSL https://zero.xyz/install.sh | bash on Mac/Linux, or via NPM on Windows)
• Run zero init to create a wallet and add funds (USDC on Base)
• Point a supported agent at Zero — no further configuration needed

Once connected, the agent searches Zero for capabilities, picks the best match for the task, and calls it. Costs range from roughly $0.001 to $0.50 per call depending on the capability. Agents can also leave reviews via zero review to help other agents make better choices.

Supported Agents and Integrations

ZER0 claims compatibility with any agent that can run shell commands. The homepage lists a broad set of supported agents, including Claude Code, Codex, Cursor, Windsurf, Devin, VS Code (agent mode), Gemini CLI, Aider, RooCode, Warp, Augment Code, Factory, Amp, Jules, goose, Kilo Code, opencode, Phoenix, Zed, Semgrep, Ona, Autopilot, and Junie.

Capability Categories

The platform advertises over 4,000 capabilities spanning a wide range of use cases:

• Media & content: image generation, voiceover synthesis, audio transcription, image editing, article summarization
• Communication: sending email, posting to Slack, making phone calls
• Data & web: web scraping, PDF extraction, webpage content extraction, news search, language detection
• Business utilities: invoice validation, email verification, phone number verification, domain lookup, domain age check, contract term extraction, site uptime checks
• Travel & commerce: flight search, hotel search, product lookup
• Developer tools: code conversion, geocoding, reverse geocoding, QR code generation, website deployment

The site states a 99% success rate across these capabilities.

Privacy and Billing Model

ZER0 is explicit that it never sees the content of API calls — requests go directly from the agent to the service provider, with Zero only handling discovery. Billing is usage-based: agents draw from a pre-funded wallet, and charges are settled per call with the capability provider. There are no subscriptions or recurring fees from ZER0 itself. A limited-time welcome offer of $5 in free credits is advertised on the homepage.

Current Status

ZER0 is actively available with a public CLI install path and a Discord community for support. The site notes a SOC 2 audit is currently in progress, signaling early-stage enterprise readiness work. The welcome offer and "limited time" framing suggest the product is in an early growth phase.
