Look up one Instagram comment by post URL.

`GET /v1/instagram/comment`

> [!NOTE] **Beta.** This endpoint has not yet been verified against the live source, so fields may be missing or differ until it becomes stable. Failed calls are refunded.

> [!NOTE] **Needs a pack.** Needs a purchased pack and a verified email; free credits do not reach this endpoint. See [pricing](https://onekey.dev/pricing).

## What you get

One Instagram record in Onekey's unified shape, in `data`. If the record does not exist you get a `404 not_found` and are not charged.

## What it costs

- **2 credits** for a fresh fetch, charged only when it succeeds.
- **Free when served from cache (0.2 credit for a cached response over 100 KB).**
- **Free** if the request is invalid (never charged) or the source fails or reports not found (refunded).

## Parameters

| Name | Type | Required | Default | What it is | Constraints |
| --- | --- | --- | --- | --- | --- |
| `url` | string | yes | (required) | Url (URL) | max 500 chars; must match `https?://[^\s]{4,480}`; trimmed |

  headers: { "x-api-key": "YOUR_API_KEY" },
});
const body = await res.json();

if (body.success) console.log(body.data);
else console.error(body.error.code, body.error.message);
```

## Recorded response

A real Instagram response, recorded and returned in Onekey's shape. Fields the platform does not provide are `null`.

```json
{
  "success": true,
  "data": {
    "content": {
      "id": "3001",
      "text": "Nice one",
      "createdAt": "2025-01-01T00:00:00Z"
    },
    "engagement": {
      "likes": 3,
      "comments": 1
    },
    "author": {
      "username": "commenter",
      "avatarUrl": "https://example.com/c.jpg"
    }
  },
  "metadata": {
    "platform": "instagram",
    "endpoint": "comment",
    "cached": false,
    "stale": false,
    "age_s": 0,
    "fetched_at": "2026-01-01T12:00:00+00:00",
    "credits_charged": 2,

  },
  "error": null
}
```

## Field mapping

How this endpoint's source fields become Onekey's [unified schema](https://onekey.dev/docs/schema.md). Fields the source lacks come back as `null`.

| Source path | Onekey field | Transform |
| --- | --- | --- |
| `id` | `content.id` | - |
| `text` | `content.text` | - |
| `created_at` | `content.createdAt` | `toIsoDate` |
| `like_count` | `engagement.likes` | `toNumber` |
| `reply_count` | `engagement.comments` | `toNumber` |
| `user.username` | `author.username` | - |
| `user.avatar_url` | `author.avatarUrl` | `safeUrl` |

## Caching and freshness

- Fresh for about 5 minutes. Repeat calls in that window are served from cache and are free.
- Between 5 minutes and 1 hour the cached copy is still served instantly and marked `stale: true` while Onekey refreshes it in the background.
- If the source is down when a refresh is needed, the last copy can be served for up to 1 day more (marked stale).
- A "not found" is remembered for 1 minute and is free.
- The cache is shared across all customers, which is what keeps repeat calls cheap.

## What can go wrong

| Status | Code | What to do |
| --- | --- | --- |
| 401 | `unauthorized` | Check the `x-api-key` header. |
| 402 | `insufficient_credits` | [Add credits](https://onekey.dev/pricing); your balance must cover the price. |
| 404 | `not_found` | That record does not exist. Free; do not retry. |
| 422 | `invalid_params` | Fix the parameters using the table above. Free. |
| 429 | `rate_limited` | Wait `Retry-After` seconds, then retry. |
| 502 | `upstream_error` | The source failed. Refunded; retry with backoff. |

See [Errors](https://onekey.dev/docs/errors.md) for the full list and retry guidance.
