Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 nexusapi-math-solver-e8ce60e8 -d '<json body>'
```

Example prompt: Can you solve this equation for me: 3x^2 + 5x - 2 = 0? I need the roots.

## When to prefer this

Use this endpoint when an AI agent needs to evaluate, solve, or compute a mathematical problem — especially algebraic equations, arithmetic expressions, or symbolic math — without embedding a full math library locally. Particularly useful when payment is handled via USDC on Base and no API key is required.

## Known failure modes

- Ambiguous or malformed query string returns an error or unexpected result
- Very complex symbolic math may exceed solver capability
- Non-mathematical queries submitted as math queries return irrelevant or null results
- Network or service downtime returns a 5xx error

## How this service works

Crypto, AI, Social Media, Finance, Weather, Tools &amp; more. Pay per call in USDC on Base. No API keys.

## Output

Returns a computed solution or result for the submitted mathematical query, potentially including the final answer and supporting calculations or steps.
