## Copernicus Climate Data Store (CDS) API

- `debrid/copernicus-cds` | qualifies-with-caveat | evidence documented | binding none | category climate reanalysis and forecast archive (token-gated API) | tier free
- needs card no, phone no, ID no, institution no | verified 2026-10-23T03:24:34.450Z (live) | stale on 2026-11-23
- url https://cds.climate.copernicus.eu/how-to-api
- price USD 0
- free tier: Free data, account required: 'If you do not have an account yet, please register ... Once logged in, copy the code displayed below to the file $HOME/.cdsapirc' with url https://cds.climate.copernicus.eu/api and a personal access token. | unit: unlimited | metered on: none | read on: 2026-10-23 | source: [1] | note: No price, no byte allowance and no quota is published on the API setup page.
- per-object cap: not applicable: a retrieval request returns a packaged file (NetCDF, GRIB or ZIP) built from the requested variable, area and period | source: [1]
- retention: the archive is the product: ERA5 and the other datasets are reissued, not deleted, and a retrieval result is held for a limited period before it must be re-requested | source: [1] | note: The result-retention window is not stated on the page read; do not treat this row as a measured value.
- egress: Free. The token is identity, not payment. | metered: no | free allowance: no byte allowance published | source: [1]
- identity: email | detail: A CDS account (email registration) plus a personal access token copied into .cdsapirc, plus a licence acceptance per dataset. No card and no institution.
- interface: rest, cli
- limits:
  - request-rate: no numeric limit published on the setup page; retrievals are queued server-side and the queue position is the observable wait [1]
- limits note: The real gate is identity: registration plus a token plus, per dataset, a licence acceptance. The token is a credential and was not created here, so no retrieval was attempted.
- binding note: Nothing in the seven-kind vocabulary fails at 1 TiB/month that could be measured here; the gate that does fail is identity, which the vocabulary carries in identity_cost rather than in limits.
- interface detail: HTTPS API at https://cds.climate.copernicus.eu/api with the cdsapi python client; the token goes in $HOME/.cdsapirc. Process listing at /api/retrieve/v1/processes.
- endpoint: part of the free tier
- tooling: cdsapi (pip install 'cdsapi>=0.7.7') is the vendor's own client; curl can drive the same endpoints with the PRIVATE-TOKEN header.
- composes with: The only free ERA5-class reanalysis source; pair it with a compute sandbox because a full reanalysis pull is tens of GB and needs processing where it lands.
- reliability: Retrievals are queued and can take minutes to hours at peak; a client must poll a request id rather than expect a stream. No rate was measured because no token exists here.
- notes: Caveat is the account and the queue, not the price. This is the clearest example of a resource that is free but not anonymous: the bytes cost nothing and the token is mandatory.
- evidence note: The setup page was read and the process listing answered anonymously, which proves the service is live but not that a retrieval works. A retrieval with a real token would move this to measured.
- extras:
  - auth: personal access token in ~/.cdsapirc
  - client: cdsapi>=0.7.7
  - process_list_bytes: 25713
- evidence:
  - [1] 2026-10-23: account registration, personal access token in $HOME/.cdsapirc, cdsapi>=0.7.7, url https://cds.climate.copernicus.eu/api
  - probe:https://cds.climate.copernicus.eu/api/retrieve/v1/processes 2026-10-23: 200 with 25,713 bytes of JSON to an anonymous client - the process catalogue is public even though retrieval is not

## Copernicus Data Space Ecosystem (CDSE / ESA DIAS) - 12 TB/month of free READ, zero writable storage

- `storage/copernicus-data-space-ecosystem-12-tb-month-of-free-read` | fails-quota | evidence reported | binding volume-quota | category academic
- needs card no, phone no, ID no, institution no | verified 2026-11-03T15:34:57.981Z (live) | stale on 2026-11-18
- url https://dataspace.copernicus.eu/
- free tier: 12 TB per rolling 30 days of download via S3/OData/STAC for a Copernicus General User, 20 MB/s per connection, 4 concurrent connections, 2,000 requests/min, empty-account registration. After the transfer limit is hit, bandwidth drops to 1 MB/s and 1 concurrent connection until the 30-day total falls back under the limit. Data Workspace adds 0.1 TB/month of deferred-access transfer and 25 processed products/month. JupyterLab gives 10 GB of persistent scratch, 30-day idle expiry. | unit: TB | metered on: downloaded-bytes | read on: 2026-10-21 | source: [1]
- per-object cap: not stated | source: [1] | note: not stated
- retention: not stated | source: [1] | note: not stated
- egress: The whole quota IS egress - this is the largest free read allowance found anywhere in the programme, but there is no general-purpose bucket to write to. | metered: yes
- identity: email | detail: registration form (required fields not itemised on the page) with email verification
- interface: s3, cli
- limits:
  - volume-quota (binding): 12 TB of downloads per rolling 30 days [1]
  - per-ip-shaping: 20 MB/s [1]
  - per-ip-shaping: 4 concurrent connections [1]
  - per-ip-shaping: 1 MB/s and 1 concurrent connection after the 12 TB limit [1]
- limits note: Read-only EO products. No user-owned bucket: the S3 endpoint serves the mission archive. Registration is open to anyone with an email and is self-service.
- binding note: downloads are metered per account over a rolling 30 days; above 12 TB the rate drops to 1 MB/s and 1 connection, which is about 0.086 TB per day
- interface detail: s3
- tooling: S3 credentials self-service from the user panel against eodata.dataspace.copernicus.eu; openEO API (10,000 credits/month, temporary boost); Sentinel Hub APIs (10,000 requests/month); s3cmd/boto3 documented.
- composes with: Per account, and the 30-day rolling window means 12 TB/month sustained without cycling accounts. Creodias resells the same platform with paid extensions.
- reliability: CloudFerro-operated for ESA; the 1 MB/s throttle after the cap is a hard cliff, not a soft degrade.
- notes: the same as the free tier
- evidence note: the vendor pages of the 2026-11-03 evidence rows were read and captured (https://documentation.dataspace.copernicus.eu/Quotas.html, https://documentation.dataspace.copernicus.eu/Registration.html); a field that decides the verdict is not cited by those captures, so the rung stays reported
