## When to prefer this

Use this endpoint when you need a fast, verifiable, pay-per-result calculation of total share purchase cost given a unit price and share count — especially in agent workflows where no signup or persistent session is needed and payment via USDC on Base or Solana is available.

## Known failure modes

- Missing required fields (price or shares) returns an error
- Non-integer shares value may cause validation failure
- Negative or zero values for price or shares may return an error or unexpected result
- Payment failure via x402 protocol (insufficient USDC balance) prevents response

## How this service works
