Free tier	Data are free but gated: 'You will need to use Earthdata Login anytime you want to download Earth science data from any of the DAACs. Access to DAAC and other EOSDIS web information (e.g. about data, missions, instruments) does not require a login.' The CMR search API answers anonymously. unit unlimited; metered on none; Registration is at urs.earthdata.nasa.gov; no fee is mentioned.
Price	USD 0
Limits	request-rate (binding) CMR deploys throttling rules that return 429 with a retry-after header; a hard 180-second limit applies to any request, and paging stops at the 1,000,000th item source The CMR page names the throttle mechanism and the 180 s ceiling but publishes no numeric rate. The download path itself was not exercised because no EDL account exists here.
Binding	request-rate For a caller holding an account, CMR's throttling and the 180-second request ceiling bound a catalogue walk. For a caller without one, the EDL gate fails first - recorded in identity_cost, because the seven-kind vocabulary has no identity kind.
Identity	email Earthdata Login registration (free, at urs.earthdata.nasa.gov) is mandatory for any DAAC download; the catalogue search needs nothing.
Egress	Free. The login is identity and metrics, not payment: the registration page describes it as a user registration and profile system. free allowance: no byte allowance published
Per-object cap	not applicable: a granule is the object and its size is collection-specific. The search response measured here was 4,238 bytes.
Retention	per collection; DAACs publish their own retention, and CMR itself is a catalogue that reflects current holdings
Interface	rest, cli CMR search at https://cmr.earthdata.nasa.gov/search/ (JSON), granule download from the DAAC with an EDL bearer token or a .netrc entry; earthaccess and the EDL client wrap the token flow. endpoint: https://cmr.earthdata.nasa.gov/search/
Tooling	earthaccess (python) handles login and download; curl needs the Authorization: Bearer header; the CMR API also takes a token query parameter but marks it for deprecation.
Composes with	The climate and remote-sensing counterpart to Copernicus: two login-gated archives that between them cover reanalysis and satellite products, both needing the same kind of free account.
Reliability	CMR paging cannot pass the millionth item and granule queries without a collection stop at 10,000; a whole-archive crawl has to be sliced by collection or by time.
Notes	Caveat is identity: the bytes are free and the account is mandatory. This is the pattern is meant to separate from the anonymous sources - NASA is not a no-account source, even though nothing is charged.
Evidence note	documented The search API was exercised anonymously and the login requirement is the vendor's own sentence; no granule was downloaded, so the download path is documented and not measured.
