Free tier	'The size limit on individual attachments is 100mb for uploads via Messenger and there is currently no limit on the number of attachments that can be uploaded.' No account storage figure published. unit mixed; metered on stored-bytes
Price	none stated
Per-object cap	per-object-cap: 100 MB (100000000 bytes)
Retention	Fetching the same object with the signature stripped and the filename changed still returned 200 with the identical 498,804 bytes — so Intercom CDN URLs are effectively unauthenticated and permanent, which is a reusable pattern (and means 'signed' URLs elsewhere may also be decorative).
Egress	Free, Intercom CDN. Signed URLs with `expires` + `signature` params.
Identity	institution derived from the record's prose, not from an identity field, and no signup was executed: incoming email including all files. request-rate: Intercom API rate limits apply. Retention: no expiry documented. paas
Limits	per-object-cap per-object-cap: 100 MB source per-object-cap: 100 MB (Messenger), 20 MB total per incoming email including all files. request-rate: Intercom API rate limits apply. Retention: no expiry documented.
Binding	per-object-cap the per-object cap sets the shard size and therefore the object count; it bounds the total more tightly than any headline quota
Interface	rest rest
Tooling	Intercom REST API (`/articles`, `/files`), official SDKs.
Composes with	100 MB x unlimited attachments would be per-record-unlimited, but there is no free plan — all tiers start with 'Start free trial'. Cannot be multiplied into free storage.
Reliability	Important control: the CDN `signature` is NOT verified. Fetching the same object with the signature stripped and the filename changed still returned 200 with the identical 498,804 bytes — so Intercom CDN URLs are effectively unauthenticated and permanent, which is a reusable pattern (and means 'signed' URLs elsewhere may also be decorative).
Notes	'The size limit on individual attachments is 100mb for uploads via Messenger and there is currently no limit on the number of attachments that can be uploaded.' No account storage figure published.
