Durable retry bookkeeping, so backoff survives the session that died. Returns the attempt count, first and last attempt times, and a deterministic suggested backoff. Pass record:true to count this attempt. $0.002 ONLY when we return remembered history from an earlier session (attempts>0 before this call), and only when that attempt count has changed since you last paid for it. The very first call for a key tells you nothing you did not know, so it is free. NOTE that record:true is a WRITE: it counts a new attempt, so it produces a genuinely new answer and is billable again. Use the default record:false to read the history without changing it. Costs $0.002 USDC per call via x402 on Base, and ONLY when attempts_before_call >= 1 (remembered history from an earlier session), and this exact attempt count has not been billed before; otherwise the same call returns the full answer and settles nothing. Authenticate with Authorization: Bearer <agent_secret>, or pass agent_key as an argument if your host cannot set headers. Equivalent HTTP route: POST /v1/retry-state.
