## OpenAPI

````yaml /openapi.yaml get /v1/posts/{postId}
openapi: 3.1.0
info:
  title: Nylon API
  version: 1.0.0
  description: |
    One API for publishing to twelve social networks.

    You address a post to connected profile ids; Nylon knows which network each
    one belongs to, what that network accepts, and how to get the media there.
    Character limits, media specs, upload protocols and threading rules are
    normalised before the request reaches a platform, and every failure comes
    back in one error taxonomy.

    ## Conventions

    - Request and response fields are `snake_case`.
    - Successful responses wrap the payload in `data`. List responses add
      `meta.pagination`.
    - Failures return `{ "error": { "code", "message", "details?" } }`.
      Branch on `code`; `message` is written for humans and may change.
    - Times are ISO 8601 with a `Z` offset.
    - Successful responses carry `RateLimit-Limit`, `RateLimit-Remaining` and
      `RateLimit-Reset`. A `429` carries those plus `Retry-After`.
