How do I fix 410 model_retired?

Line Code ids were retired on November 1, 2026. They answer 410 model_retired and are never billed.

The mapping follows how Line CLI moved saved settings (Fast → Flash, Ultra → Max, Ultra Fast → Heavy).

Good to know#

• On 429, wait the Retry-After seconds before retrying.
• When asking support about an error, send the key's name, never the key.
• Every API request sends your key and your Account ID (X-Clatter-Account: CL-…); a key alone is refused.
