Endpoint
GEThttps://market-calendar-api.onrender.com/v1/next-auction?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need the single next upcoming US Treasury auction for a specific or any term — ideal for real-time trading desks, fixed-income research tools, or financial calendar agents that need a quick point-in-time lookup rather than a full date-range list of auctions.
Side effects
- Invalid or unrecognized term string returns an error or empty result
- No upcoming announced auction for the requested term may return null or empty
- Service unavailable if the underlying render.com host is cold-starting
- Rate limit or payment failure (x402 protocol) if USDC payment is not processed
