Common errors
Every error has the same shape and says whether it was charged. The ones this endpoint can return:
| HTTP | Code | Meaning | Charged |
|---|---|---|---|
| 400 | invalid_params | A parameter is missing, has the wrong type or value, or the method is wrong. problems lists each one; param names the first.Retry: after a fix | no |
| 401 | unauthorized | The key is missing, malformed, revoked, disabled or expired (reason says which when known).Retry: no | no |
| 402 | insufficient_balance | The balance (available) cannot cover the most this call could cost (required).Retry: after a fix | no |
| 404 | not_found | The post, account or page does not exist or is not public. Endpoints whose charge_when_not_found is above 0 charge this answer (the source billed us for it): the body then says charged: true and amount.Retry: no | no |
| 429 | rate_limited | The account sent too many requests this minute (reason: rate) or has too many calls running (reason: concurrency).Retry: yes | no |
| 500 | settlement_unknown | The data came back, but the charge could not be confirmed.Retry: with the same Idempotency-Key | unknown until looked up |
| 502 | upstream_failed | Every data source for this endpoint failed on this request.Retry: yes | no |
| 503 | capability_paused | This endpoint is paused right now; nothing ran.Retry: yes | no |
| 504 | timeout | The data did not come back in time. The hold was released, so nothing was charged.Retry: yes | no |
Questions
How much does the X list followers API cost?
You pay $0.0004 for each of the accounts a call returns, at least one and at most $0.008 per call (20 accounts). 1,000 accounts cost $0.40. An empty page is billed as one item; failed calls are not charged.
How do I get the next page?
Pass page.next_cursor from the response back as the cursor parameter. When page.has_more is false there is nothing left. Every page is its own call at $0.0004.
Do I need a X (Twitter) account, cookies or a QR login?
No. You send only your okdata API key. The data is public data from X (Twitter); nothing is fetched with your own X (Twitter) account.
Am I charged when a call fails?
No. Every error response says charged: false, except a timeout, which says charged: null until the outcome is known. Resend with the same Idempotency-Key and you are never charged twice.
What if X (Twitter) does not show a field?
The field is null, and meta.unavailable names it with the reason: platform (the platform never shows it) or capability (we cannot fetch it yet).
