## Airtable (free plan) - attachment fields

- `storage/airtable-attachment-fields` | qualifies-with-caveat | evidence reported | binding request-rate | category paas
- identity a placeholder: card and phone unknown | verified 2026-10-21 (inherited) | stale on 2026-11-05
- url https://airtable.com
- free tier: 1 GB attachment storage per base on Free, with unlimited bases and 1,500 bases per workspace | unit: GB | metered on: stored-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: Free; attachments served from airtableusercontent.com (CloudFront-fronted) with expiring signed URLs | metered: no
- identity: institution
- interface: rest
- limits:
  - request-rate (binding): 33 uploads/day [1]
- limits note: 1,000 records per base on Free; 5 MB per direct API upload; 1,000 API calls per workspace per MONTH on Free; only 5 editor/creator collaborators; 1 GB per base is the billing-flag field maxTotalAttachmentSizeInBytes=1000000000
- binding note: calls are bounded rather than bytes, which is fatal to a nightly job on a monthly counter
- interface detail: rest
- tooling: Official Web API v0: POST /v0/{baseId}/{recordId}/{attachmentFieldId}/uploadAttachment accepts raw bytes up to 5 MB, larger files go via the content.airtable.com upload-then-attach flow
- composes with: 1 GB x 1,500 bases x N workspaces = ~1.5 TB per free workspace as documented, multiplied by unlimited free workspaces. Pricing config also states 'unlimited bases' on Free; the 1,500 figure is the per-workspace cap. This is the single largest documented multiplicative figure in this area.
- reliability: 1,000 API calls per month on Free is a hard wall - that is ~33 uploads/day, so the 1.5 TB chain is rate-limited long before it is capacity-limited.
- notes: the same as the free tier
- evidence:
  - [1] 2026-10-21: 'How many bases can a single workspace store? 1500 Bases per workspace'; also '1000 records per base... 1GB per of attachment storage per base' for the Free tier
  - [2] 2026-10-21: (raw page JSON) - Free plan object: maxTotalAttachmentSizeInBytes=1000000000, maxRowsPerApplication=1000, 'descriptionMarkdown: Unlimited bases / 1,000 records per base / 1GB attachment space per base'; Enterprise: maxTotalAttachmentSizeInBytes=1000000000000 (1 TB/base)
  - [3] 2026-10-21: 'Upload an attachment up to 5 MB to an attachment cell via the file bytes directly'
  - [4] 2026-10-21: probe: GET -> HTTP 401 (API live, auth-gated)
