# Tickers ranked by how many members of Congress traded them

`GET https://api.skylit.ai/v1/congress/top-names`

API: Flowseeker.

Tickers ranked by DISTINCT members disclosing a buy (or sale) in the
window; one member filing several lines counts once. Windows are on
the disclosure date, default the last 30 days, and span at most 366
days. `meta.totalNames` is the number of tickers meeting the filter
before `limit`.

## Authentication

Send your Skylit API key as a bearer token: `Authorization: Bearer <key>`. No other header is accepted.

## Parameters

| Name | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| `date_start` | query | string (date) | no | Inclusive start on the disclosure date (`YYYY-MM-DD`). Defaults to 30 days before `date_end`. Max span 366 days. |
| `date_end` | query | string (date) | no | Inclusive end (`YYYY-MM-DD`). Defaults to today (ET). |
| `side` | query | string | no |  (one of `buy`, `sell`, `all`; default `buy`) |
| `min_members` | query | integer | no | Drop tickers with fewer distinct members on `side`. (default `1`; min 1) |
| `limit` | query | integer | no |  (default `50`; min 1; max 500) |

### 400

Request validation failed.

invalidParam:

```json
{
  "error": {
    "code": "INVALID_PARAMETER",
    "message": "Invalid value 'bogus' for 'timeframe'. Allowed: 5m, 15m, 1h, 4h, 1d."
  }
}
```

### 401

Missing or invalid API key.

missingKey:

```json
{
  "error": {
    "code": "UNAUTHORIZED",
    "message": "Authentication required"
  }
}
```

### 402

The account's shared Skylit credit balance is lower than this route's cost. Top up to continue. Carries `X-Credits-Remaining: 0`.

Headers: `X-Credits-Remaining`.

outOfCredits:

```json
{
  "error": {
    "code": "insufficient_credits",
    "message": "Out of credits. Top up to continue making requests."
  }
}
```

### 403

Unknown, revoked or expired API key (the gateway's `forbidden`), the account's API access is suspended (`account_suspended`) or blocked (`account_blocked`). Not retryable.

badKey:

```json
{
  "error": {
    "code": "FORBIDDEN",
    "message": "Access to this API has been disallowed"
  }
}
```

accountSuspended:

```json
{
  "error": {
    "code": "account_suspended",
    "message": "API access has been suspended for this account. Contact support."
  }
}
```

### 429

Either the key exceeded its requests-per-minute limit (`X-RateLimit-Limit`; no `Retry-After`, wait until `X-RateLimit-Reset`), or the account is over one of the API's own limits, such as the query budget (queries running at once, fresh queries per second): `TOO_MANY_CONCURRENT_QUERIES` or `RATE_LIMITED` with `Retry-After`. Not charged; retry after the wait.

tooFast:

```json
{
  "error": {
    "code": "RATE_LIMITED",
    "message": "Rate limit exceeded."
  }
}
```

queryBudget:

```json
{
  "error": {
    "code": "TOO_MANY_CONCURRENT_QUERIES",
    "message": "This account already has 16 queries running on the shared query engine across all servers (limit ch.concurrent.customer). Cached answers are not affected. Retry after Retry-After; to backfill a day, follow meta.nextCursor instead of splitting time windows. See https://www.skylit.ai/docs/api-reference/rate-limits-and-retries",
    "retry_after": 1,
    "docs_url": "https://www.skylit.ai/docs/api-reference/errors#too_many_concurrent_queries"
  }
}
```

### 500

Unexpected server error (`INTERNAL_ERROR`, `DATABASE_ERROR`). Not charged; safe to retry with exponential backoff.

internal:

```json
{
  "error": {
    "code": "INTERNAL_ERROR",
    "message": "Internal server error"
  }
}
```

### 503

Underlying data source temporarily unavailable, the credit balance could not be verified (`credit_check_failed`), or the API is paused for maintenance (`api_paused`, with a `Retry-After` header and a `retry_after` field in seconds). Not charged; safe to retry.

ingestionLag:

```json
{
  "error": {
    "code": "UNAVAILABLE",
    "message": "Live feed is degraded; please retry in a few seconds."
  }
}
```

creditCheckFailed:

```json
{
  "error": {
    "code": "credit_check_failed",
    "message": "Could not verify credit balance. Please retry."
  }
}
```

### 504

The request did not complete within 25 seconds. Not charged; narrow the window or retry.

tooSlow:

```json
{
  "error": {
    "code": "GATEWAY_TIMEOUT",
    "message": "The request took too long and was not completed. It was not charged; narrow the request or retry."
  }
}
```
