Platforms and limits

GET/v1/platforms

Each network has its own rules. Rather than hard-coding them, read them from GET /v1/platforms: the maximum text length, hashtags and mentions, the media accepted, the formats, and whether the network is open to you.

The dry run applies these same rules before you publish.
