The request body exceeds the synchronous limit of 2 MiB (or 16 MiB for POST /v1/convert/batch).

Common causes

• A large multi-page statement file sent to the synchronous endpoint
• Batching many messages into one synchronous request body

How to fix it

Use POST /v1/convert/batch (16 MiB, many items per call), or split the file.

Does it bill?

No — rejected before the engine runs. See Test vs Live Keys for the full billing rules.
