Enterprise plans and add-on packages are by quote, and overage is charged as the contract defines.

Its incident feed shows nine incidents from 10 July to 8 October 2026, all rated minor or none, the longest a degraded Air Quality Global API from 15 to 17 August (20 of 30). Trial limits are published at 100 requests a minute and 50,000 a day, and paid limits are a monthly cap set by contract (15). No 429 is documented, an exceeded limit returns 401, and guidance is limited to spreading requests and honouring Cache-Control (3 of 15). The product page states a 99.95 per cent uptime SLA, with no SLA document published (5 of 10). The v1, v2 and v3 APIs are in production, although the documentation site is labelled beta (10).\n- Performance: Pending. Latency is measured per call by our probes, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until the first probe window closes.\n- Schema \u0026 documentation 67: 168 API reference sections are generated from OpenAPI documents (version 3.2.0 in the page data), and 11 Postman collections can be downloaded, but no standalone OpenAPI file was found (18 of 25). No llms.txt (404) and no Markdown copies (0). Overviews state sources, coverage, attribution and behaviour such as the 3 pm daypart change (16 of 20). Parameters carry enums, patterns and required flags (13 of 15). Each operation has an example response, 13 documented status codes and code samples in seven languages, though the error guide says messages may vary by system (12 of 15). Paths are versioned and each API reference has a changelog section, with one dated entry in the 42 we sampled and no central changelog (8 of 15).\n- Agent ergonomics 54: Response size is controlled by choosing a duration endpoint, by the `products` field selection and compact mode on History on Demand, and by aggregation, which is capped at 10 products and 1 MB. There is no general field selection (14 of 25). Only two APIs paginate, Alert Headlines and History on Demand (10 of 20). Errors are JSON with a code and message, such as `CDN-0004` for a missing key, which we observed on an unauthenticated request. Authorisation failures and exceeded limits share 401 (11 of 20). All documented operations are GET requests, so retries are safe (15 of 20). Every v3 call needs a location plus `units`, `language` and `format`, gzip is required, and no official SDK was found (4 of 15).\n- Security \u0026 auth 48: A plain API key whose endpoints are set by the customer's package. It is accepted only in the query string, so we deducted 10. Revocation and rotation are not documented, and the best-practices page suggests a separate key per use case (10 of 30). The API is read-only (17 of 20). Alert text comes from national agencies and US alert summaries are AI-generated, with no guidance on handling that text (10 of 15). History on Demand has a usage endpoint for key consumption. The customer portal sits behind a login and was not read (3 of 15). weather.com publishes a valid security.txt that expires on 31 December 2026, and the site footer has a security incident contact. A Vanta trust centre exists but is drawn by script and was not read. No bug bounty was found (8 of 20).\n- Payments \u0026 pricing 20: No x402, MPP or L402 (0). The Standard package price is public at $500 a month for 1 million calls on an annual plan. Enterprise plans, add-on packages and overage rates are by contract (10 of 20). A 30-day trial at 50,000 calls a day is free, but it is requested by form and limited to enterprise customers. The form did not load for us, so whether it asks for a card is unchecked, and we gave half (10 of 20). A person requests the trial and sales provisions the key (0).\n- Task success: Pending. Task success needs the category task suites run through each tool, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until then. A data provider's data-quality score is published on its listing now and becomes half of this category when it's scored.\n- Maintenance \u0026 community 36: The History on Demand Direct reference records a specification change on 14 September 2026, 24 days before the check, and the documentation sitemap shows pages edited up to 5 October 2026 (30). We found one dated changelog entry in 42 API references sampled, short of three in 90 days (0). Support is by email and a ServiceNow customer portal, and the status page is updated during incidents. No public community channel was found (6 of 15). No official SDK was found (0). No package to assess (0).\n- Transparency \u0026 trust 49: A closed service. The website terms of use, updated 16 April 2026, say they do not apply to the business data APIs and refer to separate terms that we did not find published (5 of 30). The privacy policy, effective 30 April 2026, covers business contact data collected through developer.weather.com and says customer-managed personal data is used as business agreements specify. Retention is stated as as long as necessary, and no data processing agreement was found (10 of 30). No deprecation policy or dated deprecation notice was found (0). The policy says data is processed in the United States and other jurisdictions. No sub-processor list was read, since the trust centre is drawn by script (5 of 20).\n\nFix list for a coding agent, everything this grade says the listing lacks, the biggest gain first (19 items): https://www.anchorterminal.com/fixes/weather-company.md (JSON https://www.anchorterminal.com/fixes/weather-company.json)\n\n### What we couldn't check\n\n- unchecked: the trial request form at wsi.my.site.com/trial, which is drawn by script and did not load, so whether it asks for a card and which terms it links are unknown\n- unchecked: the trust centre at trust.weathercompany.com, drawn by script, so certifications, sub-processors and documents were not read\n- unchecked: the API customer portal at weather.service-now.com, behind a login, so key rotation, usage views and any terms shown there were not read\n- The terms that govern the data APIs were not found on the pricing, trial or documentation pages, so `provenance.terms` is left out\n- The 99.95 per cent uptime SLA is a figure on the product page. No SLA document was found\n- Changelog sections were read on 42 of 168 API references. The other 126 may hold dated entries\n- Overage rates, add-on package prices and Enterprise prices are by contract and not published\n- Whether a downloadable OpenAPI file exists. The reference pages embed the documents but no file link was found\n- The lead said public docs and a free trial, which is right, but the trial is limited to enterprise customers and is not self-serve\n\n### Sources\n\n- API hub home and package list: \u003chttps://developer.weather.com/\u003e (seen 2026-10-08)\n- getting started, base URL and key provisioning: \u003chttps://developer.weather.com/docs/getting-started\u003e (seen 2026-10-08)\n- authentication, rate limits and 401 behaviour: \u003chttps://developer.weather.com/docs/authentication\u003e (seen 2026-10-08)\n- error handling status codes: \u003chttps://developer.weather.com/docs/error-handling\u003e (seen 2026-10-08)\n- best practices, limits, pagination and caching: \u003chttps://developer.weather.com/docs/best-practices\u003e (seen 2026-10-08)\n- API common usage guide: \u003chttps://developer.weather.com/docs/api-common-usage-guide\u003e (seen 2026-10-08)\n- aggregation guide: \u003chttps://developer.weather.com/docs/api-aggregation\u003e (seen 2026-10-08)\n- Standard Weather Data Package contents: \u003chttps://developer.weather.com/docs/standard-weather-data-package\u003e (seen 2026-10-08)\n- History on Demand Package, archive depth: \u003chttps://developer.weather.com/docs/history-on-demand-package\u003e (seen 2026-10-08)\n- Daily Forecast API reference and operation page: \u003chttps://developer.weather.com/docs/openapi/daily-forecast-3-0-0\u003e (seen 2026-10-08)\n- History on Demand Direct reference with changelog entry: \u003chttps://developer.weather.com/docs/openapi/history-on-demand-direct-3-0\u003e (seen 2026-10-08)\n- Alert Headlines reference: \u003chttps://developer.weather.com/docs/openapi/weather-alerts-headlines-3-0\u003e (seen 2026-10-08)\n- sitemap of 168 API references with last-modified dates: \u003chttps://developer.weather.com/sitemaps/openapi-specs/sitemap/0.xml\u003e (seen 2026-10-08)\n- Postman collections: \u003chttps://developer.weather.com/docs/postman-collections\u003e (seen 2026-10-08)\n- packages and pricing: \u003chttps://www.weathercompany.com/weather-data-apis/weather-data-apis-packages-pricing/\u003e (seen 2026-10-08)\n- free trial page: \u003chttps://www.weathercompany.com/weather-data-api-free-trial/\u003e (seen 2026-10-08)\n- Weather Data APIs product page, SLA figure: \u003chttps://www.weathercompany.com/weather-data-apis/\u003e (seen 2026-10-08)\n- status page incident feed: \u003chttps://theweathercompanyapis.statuspage.io/api/v2/incidents.json\u003e (seen 2026-10-08)\n- status page components: \u003chttps://theweathercompanyapis.statuspage.io/api/v2/components.json\u003e (seen 2026-10-08)\n- unauthenticated request, 401 error body: \u003chttps://api.weather.com/v3/wx/forecast/daily/3day\u003e (seen 2026-10-08)\n- website terms of use, scope clause: \u003chttps://weather.com/privacy/terms-of-use\u003e (seen 2026-10-08)\n- privacy policy: \u003chttps://weather.com/privacy/privacy-policy\u003e (seen 2026-10-08)\n- security.txt: \u003chttps://weather.com/.well-known/security.txt\u003e (seen 2026-10-08)\n- RDAP record for weather.com: \u003chttps://rdap.verisign.com/com/v1/domain/weather.com\u003e (seen 2026-10-08)\n\n## Who's behind it (provenance 77/100, checked 2026-10-08)\n\n| Check | Finding | Points |\n| --- | --- | --- |\n| Legal entity named | The Weather Company, LLC | 20/20 |\n| Domain age | weather.com, registered 1994-08-09 (32 years) | 15/15 |\n| Endpoint on the vendor's domain | api.weather.com | 15/15 |\n| Terms of service | not found | 0/10 |\n| Privacy policy | published, but our reader couldn't read it | 7/10 |\n| Status page | theweathercompanyapis.statuspage.io | 10/10 |\n| Changelog | not found | 0/10 |\n| security.txt | valid | 10/10 |\n\nThe privacy policy, effective 30 April 2026, names The Weather Company, LLC, 1001 Summit Boulevard NE, Brookhaven, GA 30319. Its section on data collection outside consumer products covers developer.weather.com enquiries and business customers.\n\nNo terms document is given. The website terms of use (updated 16 April 2026) say they do not apply to the business data APIs, and the separate terms they refer to were not found on the pricing, trial or documentation pages.\n\nThe API answers at api.weather.com and the documentation at developer.weather.com. The company site is www.weathercompany.com (registered 1998-03-24).\n\nweather.com/.well-known/security.txt gives a security contact and expires on 31 December 2026. www.weathercompany.com and developer.weather.com return 404 for the same path.\n\nRDAP for weather.com gives a registration date of 1994-08-09 and CSC Corporate Domains, Inc. as registrar.\n\nThere is no central changelog. Each API reference has its own changelog section, most of them empty.\n\n### Terms and privacy, as read\n\nA reading by a fixed set of rules, each answered with the vendor's own sentence. Not legal advice.\n\n**Terms of service**. We found no terms of service published for this product, so there is nothing to read and the check scores 0.\n\n\n**Privacy policy** (https://weather.com/privacy/privacy-policy), read 2026-10-08. Our reader couldn't read it (the page answered HTTP 403 to our reader).\n\n\n## Live (updated 2026-10-08 21:58 UTC)\n\n- Right now: up, HTTP 401, 28 ms, checked 2026-10-08 21:53 UTC (get on `https://api.weather.com`, asks for auth)\n- Uptime 24h 100.0% (28 probes) · 30 days 100.0% (28 probes) · p50 23 ms · p95 64 ms\n- Vendor status page: none, All Systems Operational\n- Always current: https://www.anchorterminal.com/api/v1/live/weather-company.json\n\n## Probe metrics\n\nNot measured yet. Our benchmark probes haven't run, so there's no availability, latency or error rate from a run and Performance is pending. Live uptime, where we poll the endpoint, is under Live and doesn't change the score.\n\n## Prices\n\n| Item | Price | Unit | Note |\n| --- | --- | --- | --- |\n| Standard package, annual plan | $500 | per month (plan) | 1 million API calls a month |\n| Call on Standard, at the plan cap | $0.50 | per 1,000 requests | $500 over 1 million calls |\n\nAcross all listings: https://www.anchorterminal.com/prices/index.md\n\n## Strengths\n\n- 168 API reference sections on developer.weather.com are generated from OpenAPI documents, with enums, patterns, required fields, example responses and 13 response codes per operation.\n- The Standard package covers current conditions, daily and hourly forecasts to 15 days, alerts from six national agencies, imagery, marine tiles, tides and air quality.\n- History on Demand returns hourly gridded history at about 4 km from June 2015, in JSON, CSV or Parquet, with paging, field selection and a compact mode.\n- The status page lists 16 components. Its feed shows nine incidents between 10 July and 8 October 2026, all rated minor or none.\n- The Standard package price is public, $500 a month on an annual plan for 1 million calls, and the trial allows 50,000 calls a day for 30 days.\n\n## Weaknesses\n\n- No self-serve signup. The trial is requested through a form, is limited to enterprise customers, and the Buy now button opens a contact form.\n- The API key is accepted only as the `apiKey` query parameter, so it appears in every request URL. No header option is documented.\n- The website terms of use say they do not apply to the data APIs and point to separate terms, which we did not find published.\n- Exceeding a rate limit returns 401, the same status as a missing key. No 429, Retry-After or backoff guidance is documented.\n- No llms.txt, no downloadable OpenAPI file, no official SDK and no MCP server were found. Only one dated changelog entry appeared in 42 API references sampled.\n\n## Before you call it (notes for agents)\n\n1. Send `units`, `language` and `format=json` with a location on every v3 call, plus `Accept-Encoding: gzip`, which the usage guide marks as required.\n2. Keep the key out of logs and client-side code, because it travels in the query string as `apiKey`.\n3. Treat a 401 as either a bad key, an endpoint outside the key's package or an exceeded limit, and treat a 204 as no data for the query.\n4. Each forecast duration (`3day` to `15day`) is a separate entitlement. Request only durations the contract covers.\n5. Use `/v3/aggcommon` to combine up to 10 products in one request. Each product and each location still counts as one call.\n\n## Connect\n\nFirst request:\n\n```bash\ncurl --compressed \"https://api.weather.com/v3/wx/forecast/daily/3day?geocode=33.74,-84.39\u0026units=e\u0026language=en-US\u0026format=json\u0026apiKey=$TWC_API_KEY\"\n```\n\nThrough letme (picks today, calling later): https://letme.dev/weather-company. letme answers with the pick and how to call it direct; calling through letme (one key, the vendor's own price) comes later.

The badge or a plain link to this page verifies the listing, from a page on weather.com or weathercompany.com or one of their subdomains. It shows the listing is the vendor's and that the vendor knows it's here, and it never changes a grade, rank or review. The vendor sends the page's address to `POST https://www.anchorterminal.com/api/v1/verify` as `{\"slug\": \"weather-company\", \"url\": \"…\"}`, or calls the `verify_listing` tool at https://www.anchorterminal.com/mcp. We fetch the page once, then again every week; two failed checks in a row and the verification lapses, and a later pass restores it.
