Cozi Family Organizer vs Truto Unified Calendar API

Cozi Family Organizer 15

No readable 90-day incident record established (5). The consumer or commercially available product is documented (10). No public external-agent rate limits, safe-retry contract or SLA were verified (0).

Truto Unified Calendar API 77

Graded as a hosted service on the Unified Calendar API. Better Stack status page with components for api.truto.one health, ping and link-token endpoints and the static IP proxy, with incident history (20). The feed lists "APIs and Dashboard are down" on 29 October 2026 and delayed sync jobs and webhooks on 1 November, which counts as one major outage (10). Truto's own limit is 50 requests every 10 seconds per integrated account, in front of each vendor's (15). A vendor 429 comes back with Retry-After and normalised ratelimit-limit, -remaining and -reset headers, with no idempotency guidance for creates (12 of 15). The Enterprise plan lists an SLA guarantee (10). Generally available (10). 20 + 10 + 15 + 12 + 10 + 10 = 77.

Cozi Family Organizer 10

Documented user workflows and handoff controls earn 10 points. External-agent output controls, batching and safe write retries were not verified. Do not infer a callable API from the product's own AI functions.

Truto Unified Calendar API 71

truto_exclude_fields, truto_ignore_remote_data, truto_key_by and response formats (unified, raw, normalized) size the reply (22 of 25). Query operators such as [gt] and [in], sort_by, limit and cursors, with a meta endpoint that says which filters each vendor supports (18 of 20). Errors name the HTTP status and say whether Truto or the provider failed, with the provider's message extracted (18 of 20). No idempotency key found for creates (5 of 20). Every call needs only the token and integrated_account_id; a CLI and the Link SDK exist, with no general API SDK found (8 of 15). 22 + 18 + 18 + 5 + 8 = 71.

Cozi Family Organizer 15

Public product and help material earns 15 points for explaining user workflows. No external-agent machine contract, input schemas or API error catalogue was verified. This score concerns integration documentation, not consumer usability.

Truto Unified Calendar API 75

An OpenAPI specification is linked from the RFC 9727 API catalogue, but the file timed out and was not read, so it is credited as published and unverified (20 of 25). llms.txt and a Markdown sibling for every page (10). Parameter descriptions say what each does and what it falls back to, such as end_time defaulting to the month of start_time (15 of 20). Types, required marks and allowed values such as focus_time and out_of_office (13 of 15). One documented error shape with provider and Truto fields; few request examples on the reference pages read (12 of 15). Deprecated admin endpoints are marked, but no API changelog was found (5 of 15). 20 + 10 + 15 + 13 + 12 + 5 = 75.

Cozi Family Organizer 0

No dated service release series, support-response sample, official developer SDK or dependency health evidence established (0). An active website alone is not a release history.

Truto Unified Calendar API 50

No API changelog, so the last API change can't be dated; the official @truto/truto-link-sdk was published as 1.3.5 on 26 October 2026, which we take as the latest dated release (20 of 30, since it is the connection widget, not the calendar API). Six Link SDK versions since 8 August (10 of 20, for the same reason). Support through Slack on paid plans, with no public tracker (5 of 15). A CLI and the Link SDK are official, with no API client (10 of 15). Package health not checked (5 of 10). 20 + 10 + 5 + 10 + 5 = 50.

Cozi Family Organizer 10

Published account, privacy and user-control documentation earns 10 points. No external-agent credential scopes, per-call audit contract or complete least-privilege API were verified. Vendor security statements were not independently audited.

Truto Unified Calendar API 52

API tokens are per environment and sent as Bearer headers; no scopes or expiry for them were found (20 of 30). Per-account MCP servers can be limited to read methods or tags and set to expire, and the customer's connection form can restrict access to specific resources, but the REST token reaches every integrated account in its environment (14 of 20). Event titles, descriptions and attendee text from outside parties pass through, and no prompt-injection guidance was found (0). Plans keep request logs 30 or 90 days (10 of 15). SOC 2 is stated in a 2023 blog post, with no trust page, security.txt or disclosure policy found (8 of 20). 20 + 14 + 0 + 10 + 8 = 52.

Cozi Family Organizer 40

Published product, commercial and privacy disclosures earn 35 points. Governing API terms, service-specific retention, deprecation commitments and infrastructure locations were not all established. Where only website terms were found, they are not presented as a partner API agreement.

Truto Unified Calendar API 61

Closed service under terms naming Yin Yang Inc. (15 of 30). Truto says it stores no customer data and calls vendors live, logs are kept 30 or 90 days by plan, data is kept 15 days after termination, and a DPA is public (25 of 30). Deprecated admin endpoints are marked with no policy or dates (6 of 20). Enterprise customers can choose a data region and tokens can be stored regionally; no subprocessor list was found (8 of 20). 15 + 25 + 6 + 8 = 54.
