## Errors

Errors share one shape: code, request_id, message and message_zh (a fixed sentence per code), charged, retry, retry_after_seconds, param and docs_url, with the specifics in problems. They are not charged; only settlement_unknown is unknown until looked up. The full table: https://okdata.online/docs/errors/

## Questions

### How much does the X account followers API cost?

You pay $0.0001 for each of the accounts a call returns, at least one and at most $0.02 per call (200 accounts). 1,000 accounts cost $0.10. 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 $0.0001.

### 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).

Prices from price book 1b273c48fea9634e. [Every price on this platform](https://okdata.online/pricing/x/)

- New accounts get $0.10 of credit, no card needed: enough for 1000 accounts from this endpoint.
- 1,000 accounts cost $0.10.

## Known limits

- About 200 accounts come back per page; the platform sets the page size, so there is no page-size parameter.
- For the next page, pass `page.next_cursor` back as `cursor`. A cursor stays valid for 24 hours. When `page.has_more` is false there is nothing left.

## Fields by view

The view column is the smallest `view` a field comes back in: `compact` returns only compact fields, `standard` adds the standard ones, `full` returns everything. The default is `standard`.

- `compact`: `id`, `url`, `username`, `name`, `bio`, `followers`, `following`, `posts`, `likes`
- `standard`: `avatar_url`, `verified`
- `full`: `ext`

## Common errors on this endpoint

| HTTP | Code | Meaning | Charged | Retry |
|---|---|---|---|---|
| 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. | no | after a fix |
| 400 | `cursor_mismatch` | The cursor was sent to another endpoint, or with other parameters than the page it came from (view and fields may change). | no | after a fix |
| 401 | `unauthorized` | The key is missing, malformed, revoked, disabled or expired (reason says which when known). | no | no |
| 402 | `insufficient_balance` | The balance (available) cannot cover the most this call could cost (required). | no | after a fix |
| 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. | no | no |
| 410 | `cursor_expired` | The cursor is older than the endpoint's cursor lifetime (page.cursor_expires_at said when). | no | no |
| 429 | `rate_limited` | The account sent too many requests this minute (reason: rate) or has too many calls running (reason: concurrency). | no | yes |
| 500 | `settlement_unknown` | The data came back, but the charge could not be confirmed. | unknown until looked up | with the same Idempotency-Key |
| 502 | `upstream_failed` | Every data source for this endpoint failed on this request. | no | yes |
| 503 | `capability_paused` | This endpoint is paused right now; nothing ran. | no | yes |
| 504 | `timeout` | The data did not come back in time. The hold was released, so nothing was charged. | no | yes |
