X post API

X post data in one REST call — normalized to the stable JSON schema shared across every FetchPI platform.

1 documented endpoints
GET /v1/x/posts/{id}

Contract summary (English): Get a normalized X post (capability x.post)

Normalized response entity: x/post
capability: x.post

Every response also carries freshness (cache / default / live) and billing metadata.

Use cases

Feed content-analysis pipelines with structured {{platform}} posts: text, metrics, timestamps and media references.
Power moderation, research and monitoring workflows that need the original content plus engagement counts.
Archive {{platform}} content as stable, normalized JSON instead of brittle page scraping.
