Apollo Enrich Rate Limits

Apollo applies a fixed-window rate limiting strategy to API calls, and the applicable limits are determined by your Apollo pricing plan (higher tiers get higher limits). Apollo's documentation illustrates the model with a team that has a 200 requests-per-minute allowance distributing those calls across any interval within the 60-second window. Apollo does not publish a single fixed per-endpoint number for all customers; instead it exposes a "View API Usage Stats and Rate Limits" endpoint and a developer dashboard where you can read your account's current per-minute, per-hour, and per-day limits and remaining quota. Separately from request-rate limits, most data endpoints consume Apollo credits (email, mobile, export) which are capped by plan.

Apollo Enrich Rate Limits is the machine-readable rate-limit profile for Apollo.io on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 6 rate-limit definitions, measuring requests, records, and domains.

The profile also includes 5 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Contact Discovery, Data Enrichment, Sales Intelligence, Rate Limiting, and Quotas.

Policies

Fixed-Window Rate Limiting
Apollo counts requests within a fixed time window (per minute/hour/day); once the window's allowance is used, further calls are throttled until the window resets.
Plan-Based Limits
Rate limits scale with plan tier; higher plans and Enterprise agreements receive larger allowances.
Usage Visibility
Query the View API Usage Stats and Rate Limits endpoint or the developer dashboard to read current limits and remaining quota.
Backoff Strategy
Clients should implement exponential backoff with jitter on 429 responses and spread calls across the window rather than bursting.
Credit Consumption
Enrichment and search consume Apollo credits independent of request-rate limits; monitor credit balances to avoid data being withheld.
