| Free tier | No storage quota published. Per-attachment cap is the only hard number: 'Message attachments are limited to 100MB each.' unit mixed; metered on stored-bytes |
|---|
| Price | none stated |
|---|
| Identity | institution (inferred, not read) not published |
|---|
| Egress | No per-GB egress charge found, but files are fetched by authenticated API call or a short-lived download URL tied to the message — not an anonymous CDN path. |
|---|
| Per-object cap | not stated |
|---|
| Retention | Retention is governed by the org's retention policy (license-dependent); free-tier spaces are not a documented permanent store |
|---|
| Interface | rest rest |
|---|
| Tooling | webexteamssdk / webex-python-sdk; POST /v1/messages with multipart files, GET /v1/contents/{id}. Room Tabs API can attach a persistent URL to a space but does not store bytes. |
|---|
| Composes with | 100 MB/attachment x unlimited messages in a space is genuinely large in principle, but free Webex accounts have message-retention limits and the org pays per user beyond the free tier. |
|---|
| Reliability | Retention is policy-driven rather than fixed, so an admin policy change or license lapse can remove content without any API-visible warning. Unverified for the free tier specifically — blocked from the retention help page. |
|---|
| Parsed numbers | |
