Free tier	Free plan: 100,000 calls a month, with realtime weather, a 3-day forecast, the past 1 day of history, 1-day marine weather, and the search, astronomy and IP lookup APIs. unit requests; metered on request-count; Past 100,000 calls no data is served until the quota resets at 00:00 UTC on the 1st of the month. No bulk path on the Free plan: Bulk Request (up to 50 locations a call) starts at Pro+.
Price	none stated
Limits	request-rate (binding) 100,000 calls a month; past it no data until 00:00 UTC on the 1st source request-rate (binding) unverified: behind a sign-up; no per-minute number for the Free plan is published: the terms name a per-minute burst limit and say rate limits by plan are on the pricing page, whose plan table has no rate-limit row, and a blog post names a per-second ceiling by plan and HTTP 429 for a burst source
Binding	request-rate 100,000 calls a month is about 3,333 a day over 30 days and is the only published ceiling; the burst limit has no published number.
Identity	email The email sign-up form asks for an email that becomes the username, a password twice, an arithmetic check and acceptance of the terms, or a Google sign-in; the home page says no credit card is required. A new account starts on a 7-day Business trial and moves to the Free plan when it ends.
Egress	not applicable
Retention	not applicable: the unit is a request
Interface	rest REST over HTTPS with the key in the key query parameter; JSON or XML answers endpoint: https://api.weatherapi.com/v1/current.json
Tooling	any HTTP client; the key goes in the key query parameter
Composes with	A keyed point-weather source with one monthly count: current conditions and 3-day forecasts per location, with only the previous day of history on the Free plan.
Reliability	A call with no key answers HTTP 401 with error code 1002; a call over the monthly count answers HTTP 403 with error code 2007 and no data is served until the quota resets. The error table lists no code for the per-minute burst limit and so does not say what a call over it answers; exceeding it can suspend API access for a time.
Notes	Storage: cached responses are bounded at 60 minutes for current conditions and 24 hours for forecasts; historical data has no caching limit. Bulk path: none on Free; Bulk Request starts at Pro+ (USD 25 a month on the pricing page).
Evidence note	documented Quota, plan contents, caching limits and sign-up fields are read from first-party pages; a call with no key answered HTTP 401, so the free key was not exercised.
