Zero
A service that lets your AI agent instantly use thousands of tools and APIs — sending an email, generating an image, scraping a page — without you creating an account or an API key for each one, paying pennies per call as it goes.

Description
Connecting an AI agent to a new external tool usually means signing up for that tool's service, generating an API key, and wiring it into your agent's configuration — repeated for every tool you want it to use. Zero removes that friction: install it once, and your agent gets access to a huge marketplace of tools and services on demand, paying a tiny amount per call instead of you setting up dozens of separate accounts.
Zero works with Claude, Codex, Gemini and other CLI-based AI agents, exposing access to over 41,000 services and APIs spanning image generation, video creation, web scraping, email sending, code execution and website deployment. There's no manual API key setup: the agent identifies and uses the right service in real time during a conversation, and Zero settles payment directly with the service provider on a per-call basis, billed in USDC on the Base blockchain rather than through a subscription. Zero states it doesn't see the contents of requests, and pricing is transparent with no markup added on top of what the underlying service charges. A community rating and review system helps surface reliable services, and there's a CLI for giving feedback. It launched with a $5 welcome credit and was ranked #3 Product of the Day on Product Hunt.
💬 Our review
The short version: Zero is a clever fix for a real annoyance — API key sprawl across dozens of tools — and worth trying with the free $5 credit, but the crypto-based billing (USDC on Base) is a genuine adoption barrier for anyone not already comfortable with a crypto wallet.
Against Composio or Toolhouse, which also aim to give AI agents broad tool access, Zero's differentiator is the pay-per-call, no-subscription model and the sheer breadth of the catalog (41,000+ services); Composio and Toolhouse tend to lean more toward curated, developer-friendly integration libraries with traditional billing. The tradeoff is real: needing USDC and a Base-compatible wallet is friction that a subscription-based competitor doesn't impose, and a marketplace of 41,000+ community-listed services will inevitably include some of inconsistent quality, which is why the rating system matters — read it before trusting an unfamiliar service with anything important. For a developer already comfortable with crypto rails who wants breadth over curation, it's a strong pick; for someone who just wants to add three or four well-known tools without setting up a wallet, a traditional integration platform will be simpler.
