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 omniapi-math-solver-cc0a21ec -d '<json body>'
```

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

## When to prefer this

Choose this endpoint when you need programmatic math solving via a pay-per-call API with USDC micropayments and no subscription required. It is suitable for agents needing on-demand computation without maintaining a dedicated math service. Prefer it when integrating into x402-compatible workflows on multi-chain infrastructure.

## Known failure modes

- Malformed or ambiguous query string returns an error or unexpected result
- Unsupported mathematical notation or function not recognized
- Network or server error from the Vercel deployment returning 5xx
- Payment failure via x402 preventing request from completing
- Very complex or computationally heavy expressions may time out or return incomplete results

## How this service works

444 endpoints across 9+ chains. Crypto, AI, Social, Finance, Weather, Tools. Pay per call in USDC via x402 with 4 facilitators: Dexter, Meridian, FluxA, GoPlausible.

## Output

Returns a computed answer or solution to the submitted math query, likely including the result value and potentially intermediate steps or formatted output depending on the query type.
