Facebook Followers API

AI prompt

Paste this into your AI assistant. It already holds this endpoint's parameters, response fields and an example request, so the assistant can ask what you need and then write the scraper.

Please help me write a data collection script with the EveryInfra Facebook Followers endpoint (facebook/followers).

Endpoint contract:
- Request: POST https://api.everyinfra.com/api/v1/social with the header Authorization: Bearer <API key>. Read the key from the EVERYINFRA_API_KEY environment variable and never hard-code it.
- In the request body, set platform to facebook and action to followers, and put the parameters inside params.
- Required parameters:
  - username: Specifies the Facebook account or Page identifier without an @ symbol for the followers action.
- Optional parameters:
  - channel: This parameter is used for compatibility with the account identifier in the followers action. If username is supplied, it takes precedence, and public requests must still include the required username parameter.
- Returns one object. Main fields: id, username, url, follower_count, following_count, post_count, like_count, connection_count, precision.
- Example request body:
{
  "platform": "facebook",
  "action": "followers",
  "params": {
    "username": "zuck"
  }
}
- Price: $1.39 per 1,000 requests; failed and empty results are not charged.
- For dozens or hundreds of targets, add "mode": "async" to the body: you get a job_id at once and poll GET https://api.everyinfra.com/api/v1/jobs/{job_id} for the result.
- On 422, fix the request using the suggested parameter names and allowed values in the error; on 429 or 503, wait for Retry-After and try again.

Before writing code, ask me which targets I need, how many, which fields, and what output format I want; then confirm the plan and the rough cost with me.

Request parameters

Code samples

curl -X POST 'https://api.everyinfra.com/api/v1/social' \
  -H "Authorization: Bearer $EVERYINFRA_API_KEY" \
  -H 'Content-Type: application/json' \
  --data-raw '{
  "platform": "facebook",
  "action": "followers",
  "params": {
    "username": "zuck"
  }
}'

[OpenAPI definition (JSON)]Samples read the key from the EVERYINFRA_API_KEY environment variable; copied code never contains your key.

Response example

{
  "id": "req_…",
  "platform": "facebook",
  "action": "followers",
  "results": {
    "id": "zuck",
    "username": "zuck",
    "url": "https://www.facebook.com/（已隐去）",
    "follower_count": 121476586,
    "precision": "exact",
    "platform": "facebook"
  },
  "billing": {
    "charged": …,
    "charged_usd": …,
    "balance_after_usd": …,
    …
  },
  "quota": { … }
}

Response fields

Business data is in results. The table lists the fields a record can contain; values the platform does not show are never made up.

Errors and billing

401

Missing or invalid key. Authentication runs before parameter checks, so unauthenticated requests never see the parameter schema.

422

Wrong parameter name or value. The error lists the parameters and allowed values this capability accepts and the closest match; it happens before any charge.

402

Insufficient balance. Top up first.

429

The account's per-minute request limit was reached (all of its API keys count together; a key's own lower limit applies first). Wait for Retry-After and try again; a rate package in the console raises the limit.

503

Could not complete right now. Any charge for the call goes back to your balance automatically, and the billing receipt in the response states the actual outcome, including when it is not yet known. Do not resend blindly.

200 empty

The request completed without data and is not charged (billing.reason = empty_result_refunded).

Official references

Used only to check objects and terms. They do not imply authorization or endorsement of EveryInfra by the platform.

• Facebook: Following a Page Is Distinct from Liking It ↗

  Official Facebook documentation explains that Follow is used to receive Page updates and notes differences for Pages transitioning from Like to Follow structures; this differentiates `follower_count` from `like_count`, but does not indicate that this platform can export follower lists.
