v1.1→v2

The deprecation, the gates, the third-party seam.

Filed by Michael Park
Section: developer reference

Twitter API v2 is the current generation of the official X developer platform. It replaces v1.1, which X Corp has deprecated on a rolling schedule. Most new official documentation, code samples, and SDKs target v2 exclusively.

What follows: what the version bump changed, what it broke, and where the third-party seam offers a different model entirely.

Where the third-party seam fits

TwitterAPI.io is not a v2 client. It is a separate API surface, independently designed, that happens to cover the use cases pulling people to v2 in the first place — search, user lookup, follower graphs, real-time stream. Whether it is the right surface for your work depends on the constraints that brought you here.
Pick official v2 when
  • You need first-party SLA guarantees on the wire.
  • Your use case requires write actions only in the v2 paid tiers.
  • Compliance or procurement requires a direct vendor relationship with X Corp.
  • You already pay for Pro / Enterprise — no incremental third-party benefit.
Pick third-party when
  • Price-sensitive workloads. Per-call cents instead of a $200/month floor.
  • No tolerance for project review delay; you need the key in five minutes.
  • One key serving many small use cases — narrower surface to manage.
  • Fast iteration and prototyping over canonical guarantees.

Migration in four strokes

From an existing official-v2 script to TwitterAPI.io is typically a single sitting:
01

Swap base URL

From api.twitter.com/2/ to api.twitterapi.io/twitter/. The path under the base is different per endpoint; the docs.twitterapi.io reference lists every one.

02

Swap auth header

v2 carried the credential as Authorization: Bearer <token>. TwitterAPI.io carries it as X-API-Key: <key>. The key sits in /dashboard, available the moment Google sign-in completes.

03

Adapt response unpacking

v2 returns data: [...] with a sibling includes: {...} block that the caller stitches back together by id. TwitterAPI.io flattens this — each tweet object carries its embedded author profile inline. Remove the includes-join code.

04

Keep the query syntax

Operator vocabulary (from:, since:, until:, filter:, lang:, near:) is unchanged. Anything that worked in v2 search strings still works.

Notes

Note 01

Is Twitter API v1.1 still available?

Most v1.1 endpoints are deprecated by X Corp. Some still respond but with deprecation warnings; many have been removed entirely. New projects should not target v1.1.

Note 02

Is the official v2 API free?

There is a free tier (about 1,500 posts/month, limited endpoints), then paid tiers at $200/month (Basic), $5,000/month (Pro), and $42,000+/month (Enterprise). All paid tiers require project review.

Note 03

Is TwitterAPI.io a v2-compatible API?

TwitterAPI.io is an independent third-party API with its own surface — it is not a drop-in v2 client. Functionally it covers the same use cases (search tweets, fetch users, follower graphs, real-time stream) with a different request/response shape. Migration from an existing v2 script is usually thirty minutes: swap base URL, swap auth header, lightly adapt response unpacking.

Note 04

Which version should new projects use?

If your budget supports it and your use case fits the official tier policies, use official v2 — first-party guarantees, canonical documentation. If you're outside that bracket (price-sensitive, fast iteration, no tolerance for project review), a third-party API like TwitterAPI.io is the standard answer.
