Rate Limit

All API endpoints are rate limited to ensure reliability and fair usage. When a limit is exceeded, the API returns HTTP 429 Too Many Requests. Limits are applied per user (or per API key) with sliding windows; multiple windows may apply simultaneously.

Tiered endpoints and limits

Endpoints covered by tier-based limits:

• POST /v1/jobs/search (Jobs Search)
• POST /v1/companies/search (Companies Search)
• POST /v1/companies/technologies (Technographics)

Shared limits across all three endpoints:

• Paid tier applies to users who have made at least one payment.
• Free tier applies to all other users (users who have never paid or users without any payments done).

Multiple limits are applied simultaneously. A request is rejected if it exceeds any active window.

Rate limit headers

The API returns rate limit information in every response. We follow the IETF HTTPAPI draft for RateLimit headers: RateLimit header fields for HTTP. When multiple rate limits apply, header items are comma-separated and ordered consistently across headers.

IETF compliant headers

• RateLimit: Current quota status per policy. Format: "<policy-name>"; r=<remaining-requests>; t=<time-until-reset>; pk=<partition-key>.
• RateLimit-Policy: Applied policy definition. Format: "<policy-name>"; q=<limit>; w=<window-seconds>.

Other headers

These are included for client convenience:

• RateLimit-Limit: Total allowed requests for each window
• RateLimit-Remaining: Requests remaining in each window
• RateLimit-Reset: Seconds until the current window resets

The order of values in legacy headers matches the order of RateLimit items.

Example response headers:

RateLimit: "per-second";r=3;t=1;pk="dXNlcjoxMjM0", "per-minute";r=9;t=60;pk="dXNlcjoxMjM0", "per-hour";r=49;t=3600;pk="dXNlcjoxMjM0", "per-day";r=399;t=86400;pk="dXNlcjoxMjM0"
RateLimit-Policy: "per-second";q=4;w=1, "per-minute";q=10;w=60, "per-hour";q=50;w=3600, "per-day";q=400;w=86400
RateLimit-Limit: 4, 10, 50, 400
RateLimit-Remaining: 3, 9, 49, 399
RateLimit-Reset: 1, 60, 3600, 86400

Exceeding limits and best practices

• Retry with exponential backoff on HTTP 429 responses.
• Monitor RateLimit or RateLimit-Remaining and RateLimit-Reset to avoid hitting limits.
• Prefer batching and caching to reduce request counts.
• Avoid concurrent bursts that violate per-second limits.
