organization_type e.g. Company, Startup, Public, Academic, Other
organization_size e.g. Micro (0-9), Small (10-49), Medium-sized (50-249), Large enterprise (250+)
nace_code Section letter (e.g. K) or detailed code (e.g. 62.01)

Use GET …/v2/filters/options for values your key may actually use.


Rate limits and tiers

Throughput and monthly quotas depend on your key’s tier (enforced at the gateway and in service middleware).

Typical public tier profile:

Tier Approx. steady RPS Burst Monthly request quota
tier_1 2 5 10,000
tier_2 5 10 50,000
tier_3 10 20 Unlimited (subject to fair use)

Result rows also count against monthly result quotas where configured.

Responses may include rate-limit headers, for example:

http X-RateLimit-Requests-Limit: 10000 X-RateLimit-Requests-Remaining: 9843 X-RateLimit-Results-Limit: 500000 X-RateLimit-Results-Remaining: 498231 X-RateLimit-Reset: 2026-04-01T00:00:00Z

When limits are exceeded, the API returns 429 Too Many Requests.
