Free tier	20 GB per record, 10 GB per file, and explicitly unlimited records and unlimited files. unit GB; metered on unstated
Price	none stated
Limits	per-object-cap (binding) 10 GB per file source write-gated review source 10 GB per file, 20 GB per record — so 20 TB needs ~1,024 records, which trips EUDAT's 'fair share' clause: 'the uploading of large number of files or creating large number of records is not considered fair use' and they ask you to contact them first. Live rate limit header: x-ratelimit-limit: 500, x-ratelimit-remaining: 499.
Identity	email a B2SHARE account is a B2ACCESS account: B2SHARE's own login page offers only "Sign in with B2ACCESS", and B2ACCESS registers either a home-organisation identity over eduGAIN, a social identity, or a local account. The local-account form asks for a user name, a password entered twice and an email address; organisation name, common name and comments are optional. No card and no phone number is asked for.
Egress	Free, unmetered, direct per-file content URLs (GET /api/records/<id>/files/<name>/content). No egress terms or pricing exist; EUDAT is publicly funded.
Per-object cap	10 GB per file (10000000000 bytes)
Retention	a permanent service; if it draws to a close, data stays archived and accessible for at least 2 years and is migrated to other suitable repositories
Interface	rest, rclone rest
Tooling	InvenioRDM-style REST API (live: GET /api/records?size=1 -> 200 with hits/entries and per-file content links); OAI-PMH; DOI minting (10.23728). Python client via plain requests. No rclone backend.
Composes with	20 GB per record x unlimited records. 50 records = 1 TB; 1,000 records = 20 TB in one account. The docs state outright 'There is no limit to the number of files you can deposit or records you can create'.
Reliability	Rate-limited at 500 requests/window and watched for bulk growth; EUDAT says it 'will increase back-end storage capacity incrementally when necessary', which implies throttling rather than deletion, but the fair-share clause is the trigger for manual review.

Evidence 14

date	source	what it proved
2026-10-21	docs.eudat.eu/b2share/faq/	'the maximum size for a record is 20 GB; and the maximum size for a file is 10 GB'
2026-10-21	eudat.eu/services/userdoc/b2share-faq	'There is no limit to the number of files you can deposit or records you can create'; 'fair share' principle
2026-11-01	eudat.eu/services/b2access	B2ACCESS accepts a home-organisation identity over eduGAIN, an ORCID or a social identity, so an institutional account is one route among several rather than a requirement
2026-11-01	eudat.eu/services/userdoc/b2access-usage	the local B2ACCESS account is created from a user name, a password twice and an email address, with the organisation name optional and no card or phone field
2026-11-01	eudat.eu/services/userdoc/b2access-usage	registration runs through the B2ACCESS account, whose local form asks for an email address, so the identity kind is read rather than defaulted
2026-11-01	docs.eudat.eu/b2share/faq/	the per-file 10 GB and per-record 20 GB caps are unchanged on the FAQ page
2026-11-01	eudat.eu/services/userdoc/b2access-usage	the local B2ACCESS account, one of the three login routes B2SHARE accepts, is created from a user name, a password entered twice and an email address, with the organisation name optional, so the reachable minimum is an email address
2026-11-01	b2share.eudat.eu/login/	B2SHARE's own login page offers a single route, B2ACCESS, so a B2SHARE account is a B2ACCESS account
2026-11-01	docs.eudat.eu/b2share/users/overview/	registration for an upload-capable B2SHARE account is performed on the B2ACCESS site, which is what makes the B2ACCESS form fields the identity cost of this record
2026-11-01	docs.eudat.eu/b2share/users/overview/	the three accepted identities are a local B2ACCESS ID, a social ID and an organisational ID, so an institution is one route among several and not a requirement
2026-11-01	docs.eudat.eu/b2share/faq/	the FAQ answers a retention question with a permanence premise and a 2-year floor with migration assistance
2026-11-01	docs.eudat.eu/b2share/faq/	the permanence claim rests on the consortium behind the service, and the 2-year figure is conditional on the service closing
2026-11-01	docs.eudat.eu/b2share/faq/	the free tier's own source page was read again on this date and still states the 10 GB per file and 20 GB per record caps
2026-11-01	b2share.eudat.eu/api/records?size=1	an anonymous GET of the records API answers 200 and carries a per-caller request allowance of 500 with a Retry-After of 60 seconds
