Pricing.

Amanoki is in public preview. Every endpoint is callable today without authentication, subject to the free-tier rate limit. Paid tiers change the rate ceiling, not the response shape — SDK and HTTP callers written against the free tier continue to work unchanged once the billing stack opens.

Tier	Rate limit	Included	¥ / month
Free	60 rpm / IP	All public endpoints, no signup	¥0
Hobby	300 rpm	REST + websocket (planned), 30-day archive read	¥5,000
Pro	1,200 rpm	Full archive, all forecast horizons, spatial-influence	¥30,000
Pro+	3,000 rpm	Priority weather refresh, early access to new forecast families	¥100,000
Enterprise	Custom	SLA, custom templates, optional dedicated instance	—

Paid tiers open when the Paddle Merchant-of-Record integration lands. Annual billing will include two months free. Enterprise is a placeholder for volume relationships, not an open sales channel today.

Fuel-cost adjustment

The fuel-cost adjustment calendar and /v1/nencho/* sit outside this table: free to call, no account and no key, at the free-tier rate limit of 60 rpm per IP. The settled months are arithmetic on public data, and anyone can check them.

What is outside the rate limit

/v1/reference and /openapi.json — API documentation, uncounted.
/v1/health and /v1/health/deep — liveness checks, uncounted.
/ — service-discovery root, uncounted.
/v1/admin/usage — request counters, bearer-gated (no token → 404), uncounted on the public rate counter.
/v1/admin/model-performance — the serving model's held-out Brier scores, open and likewise uncounted; /stats reads it on page load.

What counts against the rate limit

All /v1/markets, /v1/status, /v1/power/{market}/{area}/*, and /v1/nencho/* endpoints.
Reads are idempotent; rate limiting is by route template, not by payload.
Client IP is the counter key (Fly-Client-IP when Fly terminates, falling back to X-Forwarded-For).

Refunds

See /refunds for the policy. Monthly subscriptions are cancellable any time; annual subscriptions have a 30-day money-back window.
