# Platform Limits

These are the size and rate limits that apply when processing data through Tediware.

## Payload Size

EDI files are limited to 1 MB each. A typical document stays far below this: 1 MB fits several thousand line items. If you expect larger files, [contact us](https://tediware.com/contact) and we can raise the limit for your account.

## Transformation Execution

JSONata transformations have a maximum execution time of 5 seconds. An expression that exceeds the limit is terminated and returns an error. If a transformation times out, simplify the expression or reduce the input data size.

## Schema Validation

JSON schema validation has a maximum execution time of 10 seconds. Validation that exceeds the limit is terminated and returns an error.

## API Rate Limits

Platform API requests are rate-limited per API key:

- **Read endpoints** (fetching results, artifacts, and the feed): 240 requests per minute.
- **Write endpoints** (submitting EDI or JSON): 240 requests per minute.

When you exceed a limit, the API responds with `429` and a `Retry-After` header telling you how many seconds to wait. The API reference Errors page covers the full response format and how to handle it.

If you need higher rate limits, [contact us](https://tediware.com/contact) and we'll be happy to help.
