Example prompt: Can you pull up the U.S. savings bond issuance and redemption piece counts broken down by series? I want to see how many bonds of each type have been issued and redeemed.

## When to prefer this

Use this endpoint when you need structured, machine-readable data on U.S. savings bond issuance and redemption piece counts by series (e.g., Series EE, I, HH). Prefer this over manual Treasury website scraping or general economic data APIs that don't specifically break down savings bond statistics by series.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 payment not accepted (402 Payment Required)
- Service unavailable: upstream data source unreachable (503 Service Unavailable)
- No parameters supported so malformed query strings are silently ignored
- Data may be stale if the upstream Treasury data source has not been updated recently
