Get started with Yep API

Rate limits

To ensure optimal performance for all users, the API enforces the following rate limits:

• 60 requests per minute per API key
• 3,600 requests per hour per API key
• 86,400 requests per day per API key

If you exceed any of these limits, you'll receive a 429 Too Many Requests response.

All API responses include rate limit headers:

Org admins can tighten these per-key via the management keys API.

Error handling

The API uses standard HTTP status codes and returns error details in the response body:

{
  "error": "Error message describing the issue",
  "request_id": "req_abc123"
}

Search endpoint

POST /api/search

Search for content across the platform. Returns a list of matching items by proxying to our advanced search service.

Base cost: $0.004/request for up to 20 results. Each additional result adds $0.001. Only returned results are charged. Highlights are included at no extra cost.

Request parameters

curl -X POST "https://platform.yep.com/api/search" \
     -H "Authorization: Bearer $YEP_API_KEY" \
     -H "Content-Type: application/json" \
     -d '{"query": "saratoga spring water", "type": "basic", "limit": 10, "language": ["en"], "location": "US"}'

const YEP_API_KEY = process.env.YEP_API_KEY;

    method: 'POST',
    headers: {
        'Authorization': `Bearer ${YEP_API_KEY}`,

Content types

The following content types can be used with the content_type parameter. Selecting a type automatically includes all its subtypes (111 total subtypes across all types).

Supported languages

The following ISO 639-1 language codes can be used with the language parameter. You can also retrieve this list programmatically via GET /api/languages (no authentication required).

Supported locations

The following ISO 3166-1 alpha-2 country codes can be used with the location parameter. Codes are case-insensitive, and UK is accepted as an alias for GB. You can also retrieve this list programmatically via GET /api/locations (no authentication required).

Management keys

Programmatically provision API keys for your organization. Authenticates with a management key, distinct from the search API keys above. Org admins mint management keys at Management keys.

Authorization: Bearer $YEP_MANAGEMENT_KEY

A management key is bound to one organization and one member; every call operates inside that scope. Keys are identified by their SHA-256 hash in all URLs.

Per-key limits

Each API key has three optional overrides: limit_per_minute, limit_per_hour, limit_per_day. When null, the platform defaults apply (60 / 3,600 / 86,400). Overrides must be at most the platform default for their window — higher values are rejected with 422.

Key object

{
  "hash": "6b3c…",
  "label": "yep_1a2b3c4d",
  "name": "production",
  "disabled": false,
  "limit_per_minute": 10,
  "limit_per_hour": null,
  "limit_per_day": null,
  "effective_limit_per_minute": 10,
  "effective_limit_per_hour": 3600,
  "effective_limit_per_day": 86400,
  "last_used_at": "2026-04-17T10:42:11+00:00",
  "created_at": "…",
  "updated_at": "…"
}

• limit_per_* is the stored override; null means the platform default applies.
• effective_limit_per_* is what's enforced right now.

List keys

GET /api/management/keys

List every API key in the organization. Results are ordered newest first.

Request parameters (query string)
