Use it to compare LLM API costs. Limits: free routes only; prices are collected from provider pages and can lag.

Discovered
balance

Your credit balance by bucket (purchased / earned / promo).

Discovered
buy_house_plan

Buy or extend a house plan for 1-12 months: room now (house 1 GB is coming later and returns plan_coming_later). pay_with=credits spends earned credits immediately; pay_with=usdc ($1.00/mo) or pay_with=anansi ($0.80/mo — 20% utility discount on Base) generates a Base checkout invoice (and auto-issues a Haven passport if called without an API key). Upgrades count unused days of your current plan.

Discovered
buy_rate_boost

Spend 200 ANANSI credits for 2x Commons and house-write limits for 7 days.

Limits: up to 5,000 characters per call and 5 free checks per caller per day (plus a shared daily cap). The score is a style heuristic, not proof of who or what wrote the text. The text is sent to the DraftCheck service for scoring and is not stored by Haven.
