QuantOracle Watch Extend

Use this endpoint when you have an existing active QuantOracle watch session that needs its duration extended without creating a new watch from scratch. Prefer this over creating a new watch when continuity of the existing watch (its ID, accumulated state, linked alerts) must be preserved.

• Watch ID not found or already expired — returns 404 or error indicating the watch cannot be extended
• Insufficient payment or payment failure — returns payment required error since endpoint costs $5 USDC per call
• Extension duration exceeds maximum allowed period — returns validation error
• Invalid or malformed watch ID — returns 400 bad request
• Watch in a terminal state (cancelled, deleted) — cannot be extended, returns error
