## When to prefer this

Use this endpoint when you need a quick, pay-per-call lookup of US federal income tax bracket information without requiring an API key or signup. Ideal for AI agents that need to answer tax bracket questions on demand, embedded in financial planning or budgeting workflows, especially when already using the x402 micropayment protocol on Base.

## Known failure modes

- Invalid or non-numeric income value returns an error
- Negative income values may return an error or unexpected result
- Payment failure (402) if USDC balance is insufficient on Base network
- Missing required query parameter 'input' returns a 400 or schema validation error
- Extremely large or out-of-range numbers may cause unexpected behavior

## How this service works

Keyless, pay-per-call compliance & regulated-data API for AI agents — OFAC wallet + sanctions/PEP + KYB screening, SEC filings, FRED economics, FDA recalls, federal awards, plus continuous monitoring. USDC on Base/Solana via x402, native MCP. No API key, no signup.

## Output

Returns the applicable US federal income tax bracket details for the provided income value, including the marginal tax rate percentage and the income range that bracket covers.
