Score Breakdown
⚙ Agent Friendliness
🔒 Security
EU-hosted (Germany), GDPR-compliant by design. Client credentials scoped to read or read-write. TLS enforced. No cookies or fingerprinting used in tracking.
⚡ Reliability
Best When
You need a GDPR-compliant, EU-hosted cookieless analytics API with a clean developer interface and no cookie consent requirements, especially for German or EU-regulated products.
Avoid When
You need individual visitor-level tracking, session recordings, or want to self-host your analytics infrastructure.
Use Cases
- • Retrieving daily visitor and pageview counts for automated reporting pipelines without consent management overhead
- • Querying referrer and UTM campaign data to feed an agent-generated marketing performance summary
- • Fetching real-time active visitor counts as a signal in site-monitoring automations
- • Pulling custom event conversion data (goal completions) to measure funnel performance
- • Comparing traffic across multiple domains managed under a single Pirsch account via the multi-domain API
Not For
- • Session replay, heatmaps, or behavioral recording — Pirsch is aggregation-only
- • Deep funnel analysis requiring individual user-level session stitching across visits
- • Self-hosted deployments — Pirsch is a SaaS-only product (the open-source SDK is for client integration, not server)
Interface
Authentication
Client credentials flow: POST client ID + secret to /api/v1/token to receive a Bearer token. Separate client credentials can be scoped to read-only or read-write. Tokens expire after a configurable TTL. API keys are per-domain.
Pricing
All plans include full API access. Pricing is based on monthly pageview volume. EU-based hosting (Germany) included in all plans.
Agent Metadata
Known Gotchas
- ⚠ Token must be refreshed before expiry — no refresh token mechanism, requires re-authenticating with client credentials
- ⚠ Domain must be verified and added to the account before any queries will return data
- ⚠ Date filters use a specific format (YYYY-MM-DD); timezone is always UTC and cannot be changed per-request
- ⚠ The client_id and client_secret for token exchange are different from the domain-level API key shown in the UI
- ⚠ Rate limit responses do not include Retry-After headers, making automated backoff implementation guesswork
