Decision tools — free during preview

Aethis is in preview. Decisions are free for everyone today, with per-IP rate limits; we’ll announce pricing before the preview ends, and existing usage patterns will inform how it’s structured. POST /decide, GET /rulesets/{id}/schema, GET /rulesets/{id}/explain, every MCP decision tool, every aethis decide / fields / explain CLI command — no signup, no key, no credit card.
  • 250 decisions per day per IP for anonymous callers
  • Use them in production, embed them in your product, evaluate rules someone else compiled
  • Same API. Same engine. Same sub-5ms deterministic semantics.
During preview, if you consistently need more than 250/day per IP, apply for access to get a per-key 250/day quota that scales with your fleet.

Rule authoring — invite-only private beta

If you want to compile your own rules from legislation, policy docs, or internal specs — upload sources, generate a DSL, publish your own rulesets — rule authoring is invite-only during preview. We approve applicants in batches as capacity allows.
  • During beta, authoring is free for approved tenants
  • You bring your own Anthropic API key (passed per-request, never stored)
  • Approved tenants get access to the full three-phase authoring pipeline (section discovery → field vocabulary → rule generation) via the CLI, MCP server, or REST API
Applying takes about 30 seconds: your email and a short note on what you want to compile. Request access → Attempting authoring endpoints without approval returns 403 Forbidden with a pointer to the signup.

Enterprise — coming soon

Self-hosted instances, private rulesets with tenant isolation, SLA-backed availability, dedicated support, custom rate limits, audit-log export, and regulated-industry compliance packaging. Pricing is under review. If you’re building something that needs these properties today, we want to talk. enterprise@aethis.ai

What counts as a decision?

One call to /decide = one decision, regardless of how many fields you pass, whether you request include_trace or include_explanation, or whether the server serves the response from its 10-minute decision cache. Listing rulesets, fetching schemas, and reading explanations are metered separately under the rulesets:* tier counters. See Rate-limit tiers for the per-endpoint daily limits.
