# Facebook Event API

Facebook Events

Returns a public Facebook event from its link or ID: name, description, start and end, venue, hosts, and exact going and interested counts. It also has whether it's scheduled, under way, over or canceled, its offset from UTC, whether it's online, the venue's address, city and coordinates, the cover, categories, ticket link, seller and price label, the group it was created in, and for a date of a recurring event its series and how many dates that has.

GET `/v1/facebook/event`

## Example

cURL:

```shell
curl -G 'https://socialtap.dev/v1/facebook/event' \
  --data-urlencode 'url=https://www.facebook.com/events/jannus-live/arch-enemy-the-black-dahlia-murder-wrath-across-north-america-2026/2513378022457980/' \
  -H "x-api-key: $SOCIALTAP_API_KEY"
```

TypeScript SDK:

```typescript
import { SocialTap } from "socialtap";

const client = new SocialTap(); // apiKey defaults to process.env.SOCIALTAP_API_KEY

const res = await client.facebook.event.get({ url: "https://www.facebook.com/events/jannus-live/arch-enemy-the-black-dahlia-murder-wrath-across-north-america-2026/2513378022457980/" });
console.log(res.data);
console.log(res.credits.charged, res.meta.request_id);
```

});
const res = await fetch(`https://socialtap.dev/v1/facebook/event?${params}`, {
  headers: { "x-api-key": process.env.SOCIALTAP_API_KEY ?? "" },

> [!NOTE]
>
> **Good to know**
>
> - metrics.attendee_count (going) and platform_specific.facebook.metrics.interested_count are exact, from the event's guest list, and response_count is the two together. The Facebook City Events API shows them rounded from a thousand.
> - A deleted event, a private one and an ID that never existed all return not_found, because Facebook answers them alike.
> - time_zone is null because Facebook names the zone logged out only by an ambiguous abbreviation (EST). utc_offset_minutes gives the local start time, except for a multi-day event in a zone Facebook names only that way.
> - Each date of a recurring event is an event of its own: its link names it, parent_id names the series, and the series' own ID returns the series.

## Query parameters

| Name | Type | Description | Example |
| --- | --- | --- | --- |
| `url` required | `string`<br>max 2,048 chars | The event's Facebook link (facebook.com/events/\<id>/, with its slugged form /events/\<venue>/\<name>/\<id>/, a date of a series /events/\<series>/\<date>/ or ?event_time_id=\<date>, or the legacy event.php?eid=\<id>; m. and web. hosts too) or its numeric ID. | `https://www.facebook.com/events/2513378022457980/` |

`url` takes Facebook Events event links; another kind of link, or another platform's, fails free with [`invalid_input`](https://socialtap.dev/docs/errors/index.md#invalid_input). Unknown parameters are rejected with a suggestion, never ignored ([Requests](https://socialtap.dev/docs/requests/index.md)).

**Parameters every endpoint accepts**

| Name | Type | Description | Example |
| --- | --- | --- | --- |
| `max_age` optional | `integer`<br>min 0 | Accept a cached response up to this many seconds old. Cache hits cost 0 credits. Omit to always fetch fresh. The Cache-Control: max-age=N request header is equivalent; max_age wins when both are sent. | — |
| `fields` optional | `string` | Return only these fields of each item: comma-separated paths in the schema's notation (id,text,metrics.view_count,segments\[\].text; a parent path keeps the whole object). Unknown paths are rejected. Applied after the cache, so it changes neither the price nor cache hits; page and meta are always returned whole. | — |

### 400

400 Bad Request: 1 error code. Free: errors cost nothing.

| Code | HTTP | Retry | Meaning | What to do |
| --- | --- | --- | --- | --- |
| `invalid_input` | 400 | No | A parameter is missing or malformed, or the link is not one this endpoint takes. | Fix the parameter named in param as the message says. For a link of the wrong kind, call an endpoint listed in details.endpoints, when there is one. |

### 401

401 Unauthorized: 1 error code. Free: errors cost nothing.

| Code | HTTP | Retry | Meaning | What to do |
| --- | --- | --- | --- | --- |
| `unauthorized` | 401 | No | The x-api-key header is missing, or its key is unknown or revoked. On the dashboard's routes: the session cookie is missing or expired. | Send a valid API key in the x-api-key header. No key yet? A person gets one at details.signup_url; an AI agent follows details.agent_auth_url. |

### 402

402 Payment Required: 2 error codes. Free: errors cost nothing.

| Code | HTTP | Retry | Meaning | What to do |
| --- | --- | --- | --- | --- |
| `insufficient_credits` | 402 | No | The account does not have enough credits for this request. | Have a person buy credits at details.purchase_url (or make them a checkout link with details.checkout), then repeat the request. Do not retry automatically. |
| `spend_limit_reached` | 402 | No | The API key reached its spend limit for this period. The account may still have credits. | Wait until details.resets_at, or raise the key's spend limit (PATCH /v1/api_keys/{id}). Do not retry automatically. |

### 403

403 Forbidden: 2 error codes. Free: errors cost nothing.

| Code | HTTP | Retry | Meaning | What to do |
| --- | --- | --- | --- | --- |
| `forbidden` | 403 | No | The API key is valid but may not make this request, and details.reason says why: the account is suspended, the key lacks the route's scope, waits for its owner to confirm it by email, has expired, or was used from an IP outside its allowlist, or a rotated key's previous secret was used for a call that needs the admin scope. A running job stops with it too when its account is suspended or the key that created it is revoked or expires. It is about the key, never the item: a private item is private_or_unavailable, also 403, so branch on the code. | Act on details.reason. suspended: contact [support](mailto:support@socialtap.dev). scope: use a key with details.required_scope. previous_secret: use the new secret. key_pending: have the owner open the emailed link. key_expired or key_revoked: create a new key. ip_not_allowed: call from an allowed IP. |
| `private_or_unavailable` | 403 | No | The item exists but is not public: it is private, age- or region-restricted, or needs a login to view. It shares 403 with forbidden (which is about the key), so branch on the code. | Only public items can be fetched. Do not retry. |

### 404

404 Not Found: 1 error code. Free: errors cost nothing.

| Code | HTTP | Retry | Meaning | What to do |
| --- | --- | --- | --- | --- |
| `not_found` | 404 | No | The item does not exist or was deleted. On GET /v1/requests/{id}/response: the response was not kept (details.reason says why). | Check the link or ID. Do not retry. |

### 429

429 Too Many Requests: 1 error code. Free: errors cost nothing.

| Code | HTTP | Retry | Meaning | What to do |
| --- | --- | --- | --- | --- |
| `rate_limited` | 429 | Yes, later | The account passed its runaway-protection ceiling: a high per-account limit that stops a broken client loop (plans have no rate limit). Requests without an API key (signup, the MCP server's tool listing and find_endpoint) are limited per IP address instead. It also stops an account whose failed requests in the last hour cost far more than its successful ones paid for: failures are free within a limit (the message says so), and successes raise it. | Wait the seconds in the retry-after header, then retry. If your steady traffic needs more, ask [support](mailto:support@socialtap.dev) to raise the ceiling; without an API key, send one. |

### 500

500 Internal Error: 1 error code. Free: errors cost nothing.

| Code | HTTP | Retry | Meaning | What to do |
| --- | --- | --- | --- | --- |
| `internal` | 500 | Yes, later | An unexpected error on SocialTap's side. | Retry with backoff. If it keeps happening, contact [support](mailto:support@socialtap.dev) with the request_id. |

### 502

502 Bad Gateway: 1 error code. Free: errors cost nothing.

| Code | HTTP | Retry | Meaning | What to do |
| --- | --- | --- | --- | --- |
| `upstream_error` | 502 | Yes, later | The platform failed, or answered with something we could not read. | Retry with backoff. Failed requests are free. |

### 503

503 Unavailable: 2 error codes. Free: errors cost nothing.

| Code | HTTP | Retry | Meaning | What to do |
| --- | --- | --- | --- | --- |
| `upstream_blocked` | 503 | Yes, later | The platform refused every attempt, our own retries included. | Retry later with backoff. Failed requests are free. |
| `overloaded` | 503 | Yes, later | SocialTap was at capacity, or paused by its operators, and did not start the request. Nothing was fetched or charged. | Retry after the seconds in the retry-after header. Failed requests are free. |

## Pricing

From **1 credit** per request. Charged only for successful requests. Errors are free. The price depends on the source that produced the result, reported as `meta.source`; sources are tried cheapest first: Platform API → Public page.

| Source | Price per successful request | Per 1,000 requests |
| --- | --- | --- |

**Balance, sources and what you were charged**

Your balance must be at least **1 credit** to start a request; with less, it is refused with [`insufficient_credits`](https://socialtap.dev/docs/errors/index.md#insufficient_credits) (HTTP 402) and costs nothing. Only that minimum is set aside when the request starts.
