## 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 finmath-random-token-generator-d1d61b1e -d '<json body>'
```

Example prompt: Generate a random alphanumeric token that is 32 characters long using the finmath API.

## When to prefer this

Use this endpoint when you need a deterministic, server-side random token generation as part of a financial math workflow on the finmath platform, especially when you are already integrated with the finmath x402 payment pipeline and want a random string without relying on client-side RNG.

## Known failure modes

- Invalid format value returns an error
- Length value out of supported range returns an error
- Payment not provided or insufficient USDC causes 402 response
- Malformed JSON body causes 400 error

## How this service works

Deterministic finance and crypto math for AI agents: TradFi (NPV, IRR, XIRR, Black-Scholes + Greeks, bonds, VaR, Sharpe) and DeFi (impermanent loss, perp liquidation, funding, Uniswap v3, health factor, cost basis). Exact, model-free arithmetic that LLMs get wrong — priced per call in USDC.

## Output

Returns a JSON object with a 'result' field containing the generated random token and a 'meta' object with metadata about the call.
