No llms.txt or Markdown docs for agents (0). The help page says what each tool does and where it stops, such as read-only source events, whole-series edits and place IDs only from a lookup, which is documentation for people rather than tool descriptions (8 of 20). Typed inputs unchecked (0 of 15). Sample prompts but no documented error responses (5 of 15). Dated product posts and App Store notes, with no versioning for the connector (5 of 15).\n- 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.\n\n### Agent ergonomics: Truto Unified Calendar API +43\n\n- Agenda Hero (28): Context cost. The help page lists about seven actions, which suggests a compact toolset, but the definitions weren't read (10 of 25). Events can be read for a date range (8 of 20). Errors. The unauthenticated 401 carries a WWW-Authenticate header with resource metadata; tool errors aren't documented (5 of 20). Annotations unchecked, and removals are immediate and permanent with no review step (0 of 20). Calendar time zone is the default, and there are no SDKs, only the MCP server (5 of 15).\n- 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.\n\n### Reliability: Truto Unified Calendar API +42\n\n- Agenda Hero (35): Read with the hosted lines, for the MCP server. A status page at status.agendahero.com (20). Its history is drawn by script and couldn't be read (5). No rate limits published for the connector or the app (0). No overload or retry guidance (0). No SLA (0). The connector is live in ChatGPT's plugin directory and not labelled beta (10).\n- 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.\n\n### Security \u0026 auth: Truto Unified Calendar API +14\n\n- Agenda Hero (38): Credential model. OAuth with three scopes (calendars:read, events:read, events:write), PKCE S256, dynamic registration and a revocation endpoint, from Agenda Hero's own metadata (30). Least privilege. The assistant can change only calendars the person can edit and only reads events from sources, but the consent screen grants all three scopes together and deletions run with no confirmation (8 of 20). Injection. Tools return event text from schools, teams and other people's calendars and no guidance on untrusted content was found (0 of 15). No audit log or per-call view for the operator found (0 of 15). No security.txt, disclosure policy, bounty or certification found (0 of 20).\n- 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.\n\n### Transparency \u0026 trust: Truto Unified Calendar API +12\n\n- Agenda Hero (49): The terms are an iubenda embed whose path iubenda's robots.txt disallows, so the licence line is unchecked and scored absent (0 of 30, unchecked). The privacy page on agendahero.com says prompts go to OpenAI or Anthropic, no data is shared for third-party model training, and Google data is removed when the person disconnects; no retention periods were readable (12 of 30). No deprecation policy or dated notices found (0 of 20). OpenAI and Anthropic are named; hosting and locations aren't (6 of 20).\n- 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.\n\n### Payments \u0026 pricing: Agenda Hero +10\n\n- Agenda Hero (30): No x402, MPP or L402 (0). Plan prices are public, Plus US$5, Family US$10 and Organizations US$20 a month, with no per-unit price (10). Free forever with no card, and the connector works on free accounts (20). A person signs up and approves the connection in a browser (0).\n- Truto Unified Calendar API (20): No x402, MPP or L402 (0). Plan prices per connector a year are public, with unlimited calls (10). A free 30-day sandbox is given after a work-email request reviewed within a business day (10 of 20).

Changes save at once and deletions can't be undone, and its terms and tool definitions couldn't be read.\n\n**Truto Unified Calendar API.** Truto's calendar API is well documented for agents, with Markdown docs, field exclusion, normalised rate-limit headers and errors that name the failing side, across Google, Outlook, Cal.com and Calendly. It is sold from $999 a connector a year through a demo, had an API outage on 29 October 2026 and has no public changelog.\n\n## Before you call either\n\n### Agenda Hero\n\n1. Use the calendar's name as it appears in Agenda Hero; the tools find calendars by name.\n2. Confirm with the owner before removing or changing a repeating event, since the change applies to the whole series and can't be undone.\n3. Don't try to edit events that come from a source calendar. They're read-only here and must be changed where they live.\n4. Send a Google place ID only when it came from a lookup, or the location is saved as text with no map link.\n\n### Truto Unified Calendar API\n\n1. Pass `integrated_account_id` on every call; the token alone reaches nothing\n2. Call the meta endpoint for the method first to see which filters the vendor supports\n3. Set `truto_ignore_remote_data=true` and list fields in `truto_exclude_fields` to keep responses small\n4. On 429 wait for Retry-After; stay under 50 requests every 10 seconds per integrated account\n5. Set `expand_recurring=true` when the task needs each instance of a repeating event\n\n## Questions\n\n### Which is better for AI agents, Agenda Hero or Truto Unified Calendar API?\n\nTruto Unified Calendar API scores 60.4 (C) on agent readiness against Agenda Hero's 34.2 (F), and leads in 5 of 7 scored categories.
