zero

Use the zero CLI: run zero search with a query to find a capability, inspect it with zero get, then call it with zero fetch. Payment is handled automatically via the x402 protocol when the server returns a 402 response.

Run zero init to generate a new wallet saved to ~/.zero/config.json, or import an existing key with zero wallet set <privateKey>. Then fund it with USDC on Base using zero wallet fund, and verify with zero wallet balance.

Zero covers real-world data and media tasks: image generation, translation, weather forecasts, local business lookups, audio and video processing, web scraping, data enrichment, currency conversion, and stock prices. It is not meant for coding or question answering the model already handles.

Pass the --max-pay flag to zero fetch with a USDC amount, for example --max-pay 0.50. The CLI refuses to pay more than that per call, which protects against unexpectedly expensive capabilities.

A 4xx usually means the request body or headers do not match the capability's schema. Run zero get <position> to check the exact method, bodySchema, and required headers, and never guess field names when bodySchema is null.

Skip zero for tasks the agent already handles natively, such as writing code, answering questions from training data, editing local files, running shell commands, or doing math. Zero is a fallback discovery layer, not a replacement for built-in abilities.
