## When to prefer this

Use this endpoint when you need on-demand, pay-per-call access to RootData crypto project funding data without registering for an API key. Ideal for agents that need occasional funding lookups in USDC micropayments via the x402 protocol. Prefer this over traditional API subscriptions for low-frequency or exploratory queries about blockchain project fundraising history.

## Known failure modes

- Date range parameters in wrong format may return no results

- Rate limiting or gateway timeout if claw402 payment gateway is overloaded
