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## Facts\n\n| Field | Value |\n| --- | --- |\n| Vendor | Yin Yang Inc. (https://truto.one) |\n| Kind | HTTP API |\n| Category | Calendars \u0026 scheduling (https://www.anchorterminal.com/categories/scheduling) |\n| Auth | API key · A Truto API token, created in app.truto.one under Settings \u003e API Tokens for one environment (development, staging or production), sent as `Authorization: Bearer`. Every request names an `integrated_account_id`, the end customer's connected calendar account, whose OAuth tokens Truto holds. Per-account MCP servers can be limited to read or write methods and tags, and given an expiry. |\n| Pricing | Paid ($83.25 / mo) · Expansion from $999 per connector a year and Enterprise from $1,999, each with unlimited connections and API calls, sold through a demo. A free 30-day sandbox is given on request with a work email, usually within one business day. |\n| x402 | No · No x402, MPP or L402 in the docs index, the pricing page or the API catalogue (checked 2026-11-06). |\n| Licence | unknown |\n| Packages | npm: `@truto/truto-link-sdk` |\n| Docs | https://truto.one/docs/api-reference/unified-calendar-api/ |\n| llms.txt | https://truto.one/docs/llms.txt |\n| Last release | 2026-10-26 |\n| Surface listed | The Unified Calendar API at api.truto.one/unified/calendar, read from truto.one's Markdown docs, pricing, status page, DPA and terms on 6 November 2026. No account or sandbox was requested and no call was made |\n| Category | Listed in scheduling, beside the unified calendar APIs aurinko-calendar, cronofy and nylas-calendar, rather than the lead's aggregator; the rest of Truto's platform is not graded here |\n| MCP | Truto can create an MCP server per integrated account that exposes that account's described Proxy API methods, limited by read or write methods and tags, with an optional expiry and an option to require an API token. It is not the unified calendar surface |\n| Plans | Expansion (30-day log retention, up to 5 environments) and Enterprise (90-day logs, single tenant, data region choice, SSO and SLA guarantee) |\n| Legal entity | Yin Yang Inc., named in the terms and privacy policy. After termination, customer data is kept 15 days, per the terms |\n| Capabilities | calendar.read, calendar.write, calendar.availability, calendar.booking, automation.auth |\n| Tags | hosted, unified-api, paid, sales-led, openapi, llms-txt, status-page, webhooks, google-calendar, outlook |\n| JSON | https://www.anchorterminal.com/api/v1/tools/truto-calendar.json |\n\n## Score breakdown (methodology v0.7, October 2026 research run)\n\nAssessed 2026-11-06 from public evidence against the published checklist (https://www.anchorterminal.com/benchmark/#checklist). Confidence: medium. Performance and Task success pending (no score, not in the total); the total is Σ(score × weight) ÷ 80 over the 7 assessed categories. \"This run\" is each category's share of the 100 points.\n\n| Category | Weight | This run | Score (0–100) | Points |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% | 20 | 77 | 15.4 |\n| Performance | 10% | pending | pending | n/a |\n| Schema \u0026 documentation | 13% | 16.2 | 75 | 12.2 |\n| Agent ergonomics | 13% | 16.2 | 71 | 11.5 |\n| Security \u0026 auth | 14% | 17.5 | 52 | 9.1 |\n| Payments \u0026 pricing | 10% | 12.5 | 20 | 2.5 |\n| Task success | 10% | pending | pending | n/a |\n| Maintenance \u0026 community | 7% | 8.8 | 50 | 4.4 |\n| Transparency \u0026 trust (editorial 54, provenance 67) | 7% | 8.8 | 61 | 5.3 |\n| Negative events | up to −15 | up to −15 | none recorded | 0 |\n| **Total** | | | | **60.4 → C** |\n\n### Why each score\n\n- Reliability 77 (checked 2026-11-06): 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- Performance: Pending. Latency is measured per call by our probes, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until the first probe window closes.\n- Schema \u0026 documentation 75 (checked 2026-11-06): 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- Agent ergonomics 71 (checked 2026-11-06): `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- Security \u0026 auth 52 (checked 2026-11-06): 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- Payments \u0026 pricing 20 (checked 2026-11-06): 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). A person requests access or books a demo (0). 0 + 10 + 10 + 0 = 20.\n- Task success: Pending. Task success needs the category task suites run through each tool, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until then. A data provider's data-quality score is published on its listing now and becomes half of this category when it's scored.\n- Maintenance \u0026 community 50 (checked 2026-11-06): 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.\n- Transparency \u0026 trust 61 (checked 2026-11-06): 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\nFix list, everything this grade says the listing lacks, the biggest gain first (18 items). What it covers is at https://www.anchorterminal.com/fixes/truto-calendar.md (JSON https://www.anchorterminal.com/fixes/truto-calendar.json).

Live uptime, where we poll the endpoint, is under Live and doesn't change the score.\n\n## Prices\n\n| Item | Price | Unit | Note |\n| --- | --- | --- | --- |\n| Expansion plan connector | $83.25 | per month (plan) | From $999 per connector a year |\n| Enterprise plan connector | $166.58 | per month (plan) | From $1,999 per connector a year |\n\nAcross all listings: https://www.anchorterminal.com/prices/index.md\n\n## Strengths\n\n- One REST shape for Google Calendar, Outlook Calendar, Cal.com and Calendly, including availability and event types\n- Markdown copy of every docs page and an llms.txt index\n- `truto_exclude_fields`, `truto_ignore_remote_data` and response formats to size replies\n- Errors say whether Truto or the provider failed, and vendor rate limits come back as standard headers\n- Pass-through design with no stored customer data, and a public DPA\n\n## Weaknesses\n\n- Priced from $999 per connector a year with a demo-led sandbox\n- An outage of the APIs and dashboard on 29 October 2026 is on the status page\n- No public changelog for the API\n- API tokens are per environment with no scopes found\n- Only five calendar integrations, and Calendly support is partial on events\n\n\n\n## Before you call it (notes for agents)\n\n1. Pass `integrated_account_id` on every call; the token alone reaches nothing\n2. Call the meta endpoint for the method first to see which filters the vendor supports\n3. Set `truto_ignore_remote_data=true` and list fields in `truto_exclude_fields` to keep responses small\n4. On 429 wait for Retry-After; stay under 50 requests every 10 seconds per integrated account\n5. Set `expand_recurring=true` when the task needs each instance of a repeating event\n\n## Connect\n\nFirst request:\n\n```bash\ncurl \"https://api.truto.one/unified/calendar/events?integrated_account_id=$ACCOUNT_ID\" -H \"Authorization: Bearer $TRUTO_API_TOKEN\"\n```\n\nThrough letme: https://letme.dev/truto-calendar. letme answers with the pick and how to call it direct.

The badge or a plain link to this page verifies the listing, from a page on truto.one or one of its subdomains. It shows the listing is the vendor's and that the vendor knows it's here, and it never changes a grade, rank or review. The vendor sends the page's address to `POST https://www.anchorterminal.com/api/v1/verify` as `{\"slug\": \"truto-calendar\", \"url\": \"…\"}`, or calls the `verify_listing` tool at https://www.anchorterminal.com/mcp. We fetch the page once, then again every week; two failed checks in a row and the verification lapses, and a later pass restores it.
