## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability gadgethumans-api-hub-multi-tool-rest-mcp-gateway-36ce7758
```

Example prompt: Use GadgetHumans to generate a secure random password for me — 16 characters, mixed case, numbers, and symbols.

## When to prefer this

Choose this endpoint when you need a wide variety of developer utilities — QR codes, passwords, weather, crypto, AI text, agent memory — from a single low-cost gateway without managing multiple API keys. It is ideal for lightweight agentic workflows that need breadth over depth, especially when a free tier with no API key is acceptable. Prefer more specialized APIs when you need deep schema control, high reliability SLAs, or rich domain-specific features.

## Known failure modes

- Vague or malformed 'data' parameter results in an ambiguous or failed tool dispatch
- Unsupported tool name returns an error or empty response
- Rate limiting on the free tier may return 429 errors
- Payment not completed results in 402 response blocking the call
- Tool-specific required sub-parameters missing from 'data' string cause silent failures or incorrect output

## How this service works

MCP server with 49 developer tools + 300+ REST APIs — agent memory, QR codes, passwords, AI text, finance, health, crypto, weather, and more. Free tier, no API key needed.

## Output

Returns a JSON object with an 'ok' status and the result of the requested tool — e.g. a generated QR code image URL, a random password string, a weather forecast, a crypto price, AI-generated text, or a stored memory confirmation, depending on the tool invoked via the 'data' parameter.
