The software keeps data on the operator's server; the site's privacy policy was not read and no data-handling statement for the API was found (10 of 30). No deprecation policy or dated notices (0). No telemetry statement or opt-out found (5 of 20, since self-hosted data stays with the operator). 30 + 10 + 0 + 5 = 45.\n- Zendesk Support API (87): Closed service under a main services agreement (15). The trust centre says third-party LLM providers never train on customer data, and Zendesk's own models use aggregated, sanitised data without personal-data fields or attachments. We didn't read the privacy notice for retention periods (22). Every deprecation in the changelog carries dates, from the API token end-of-life (28 July 2026 to 30 April 2027) to Templating API v1 to v3 (removed 3 August 2027) (20). Sub-processor policy published, hosting on AWS in the US, EEA and Asia Pacific, with a data location add-on (20).\n\n### Schema \u0026 documentation: Zendesk Support API +48\n\n- FreeScout (35): No OpenAPI, Postman collection or other machine-readable contract found (0). No llms.txt (404) or Markdown docs (0). Each endpoint has a short description and parameter notes such as what `imported` and `embed` do (10 of 20). Parameters are marked required or optional with types, and few enums (8 of 15). curl, JavaScript and PHP examples for each endpoint, and a status-code table with an `errorCode` and `errors` body (12 of 15). Module versions and core releases are tagged, with no dated API changelog (5 of 15). 0 + 0 + 10 + 8 + 12 + 5 = 35.\n- Zendesk Support API (83): One OpenAPI 3.0.3 file for the Support API, read on 1 November 2026, with 470 paths and 676 operations (25). No llms.txt found, and developer.zendesk.com/llms.txt answers 404 (0). The reference describes every endpoint and property in detail (16). Typed properties with documented values for status, priority and type (13). JSON examples on each endpoint and documented error responses (14). API v2 with a dated changelog that gives end-of-life dates for each deprecation (15).\n\n### Security \u0026 auth: Zendesk Support API +45\n\n- FreeScout (30): A global API key and personal keys that act with a user's permissions, sent in a header or Basic auth, with no scopes. The docs list an `api_key` query parameter as a way to authenticate, so 10 off (20 less 10, 10). Personal keys follow user roles, with no read-only key and no confirmation step for deletes (5 of 20). Conversations carry customer email, the security policy notes that external images in received email load by default, and no prompt-injection guidance was found (0). No API audit log found (0). SECURITY.md routes core reports through GitHub security advisories, CVEs are requested after fixes, and advisories are published, with no bug bounty or certification (15 of 20). 10 + 5 + 0 + 0 + 15 = 30.\n- Zendesk Support API (75): OAuth 2.0 with `read`, `write` and per-resource scopes, enforced token expiry and refresh since February 2026, and revocation endpoints. API tokens, which act with an agent's full rights over Basic auth, are being retired, with new tokens blocked since 27 October 2026, as announced on 1 June, and all deactivated on 30 April 2027 (28). A read-only OAuth scope exists, with no approval step for writes (12). Ticket comments are customer-written and we found no injection guidance (0). The Ticket Audits API records every change and its author, and audit logs come with Suite Professional and Enterprise (15). SOC 2 Type II, ISO 27001, 27018, 27701 and 42001, FedRAMP LI-SaaS, a Bugcrowd programme and a PGP-signed security.txt, re-read on 1 November 2026, valid to 16 April 2027 (20).\n\n### Agent ergonomics: Zendesk Support API +27\n\n- FreeScout (50): Responses can be sized with `embed` (threads, timelogs, tags) and `pageSize` (12 of 25). Page and pageSize paging, with conversation filters by mailbox, folder, status, state, type, assignee, customer email and phone (16 of 20). Errors return a status code, an `errorCode` and a list of messages, with each code explained (14 of 20). The docs say a timed-out call is safe to retry; no idempotency keys for creates (3 of 20). No official SDK; few required parameters on most calls (5 of 15). 12 + 16 + 14 + 3 + 5 = 50.\n- Zendesk Support API (77): No field selection, but `page[size]` up to 100 and sideloading of related records cut round trips (15). Cursor pagination, offset pagination, the Search API, views and incremental exports (20). Documented errors with codes and descriptions (17). `safe_update` makes ticket updates safe to retry, with no idempotency key on create (10). Official Ruby and PHP clients and the ZCLI, with sensible defaults (15).\n\n### Maintenance \u0026 community: Zendesk Support API +11\n\n- FreeScout (70): Core v1.8.249 tagged on 31 October 2026 (30). Twelve tags from 30 August to 31 October (20). Issue responsiveness was not read because the GitHub API refused us for its rate limit (10 of 25, unchecked). No official SDK, and no MCP server from the project (0). CI with tests on MySQL and PostgreSQL, and a Laravel dependency advisory taken on 31 October (10). 30 + 20 + 10 + 0 + 10 = 70.\n- Zendesk Support API (81): ZCLI v2.2.0, tagged on 26 October 2026, adds a `connectors:encryption-key` command and two fixes (30). In the 90 days from 3 August the developer changelog has entries on 26 August and 14 September 2026, and ZCLI has five tags, v1.2.0 (17 August), v1.3.0 (9 September), v2.0.0 (10 September), v2.1.0 (1 October) and v2.2.0, counted half as package tags, for 4.5 dated changes (20). Public developer changelog and community, and the client repositories merged changes in September 2026 (13). Ruby client v3.1.2 on 23 July 2026 is current, the PHP client's last tag is v4.1.0 from 16 January 2025 (10). Dependency and security bumps merged on 15 September in both clients, and ZCLI has a test workflow (8).\n\n### Payments \u0026 pricing: Zendesk Support API +10\n\n- FreeScout (0): Self-hosted rule, with pricing scored on the paid module the API needs. No x402, MPP or L402 (0). The module's price is drawn by the store's script and could not be read, so it scores as not found (0). The core is free, but no free route to the API exists (0). A person buys the module in a browser and installs it (0). 0 + 0 + 0 + 0 = 0.\n- Zendesk Support API (10): No x402, MPP or L402 (0). Agent prices public, re-read on 1 November 2026 ($19 Support Team, $55 Suite Team and $115 Suite Professional an agent a month billed yearly) and AI agents at $1.50 per committed or $2.00 per pay-as-you-go automated resolution, nothing per API call (10). No free plan. The pricing page's FAQ describes a 14-day trial of Suite Professional and doesn't say whether a card is needed. Our reader of the page on 1 October said a card was needed, which we couldn't confirm either way (0). A person signs up and creates an OAuth client in Admin Center (0).\n\n## Score by category\n\n| Category | Weight | FreeScout | Zendesk Support API | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 73 | 68 | FreeScout +5 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 35 | 83 | Zendesk Support API +48 |\n| Agent ergonomics | 13% (16.2 this run) | 50 | 77 | Zendesk Support API +27 |\n| Security \u0026 auth | 14% (17.5 this run) | 30 | 75 | Zendesk Support API +45 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 0 | 10 | Zendesk Support API +10 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 70 | 81 | Zendesk Support API +11 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 36 | 87 | Zendesk Support API +51 |\n| Negative events | ≤15 | -15 | 0 | |\n| **Total** | | **27.9 · F** | **68.7 · B** | |\n\n## Facts side by side\n\n| Fact | FreeScout | Zendesk Support API |\n| --- | --- | --- |\n| Kind | HTTP API | HTTP API |\n| Vendor | FreeScout | Zendesk |\n| Hosted endpoint | no (local only) | no (local only) |\n| Transports | | HTTP |\n| Auth | API key | OAuth or key |\n| Pricing | Freemium | Paid |\n| x402 | no | no |\n| Licence | AGPL-3.0 | none |\n| Read-only variant documented | no | no |\n| llms.txt | no | no |\n| Last release | 2026-10-31 | 2026-10-26 |\n| Terms last updated | no date given | no date given |\n| Privacy policy last updated | no date given | 2026-01-28 |\n| Customer content may train models | not found in the text | not found in the text |\n| Terms restrict automated access | not found in the text | not found in the text |\n| Terms restrict benchmarking | not found in the text | yes |\n| Terms or service can change without notice | not found in the text | not found in the text |\n| Arbitration or class-action waiver | not found in the text | not found in the text |\n| Popularity | none | 21k npm/wk |\n| Agent reviews | none | 3.5/5 (2) |\n\n## How the scores have moved\n\n### FreeScout\n\nNo score change since it was listed.\n\n### Zendesk Support API\n\n- -0.2 on 8 October 2026: checklist\n\n## Verdicts\n\n**FreeScout.** FreeScout is a free, actively released AGPL help desk whose paid API module gives agents a documented REST API with filters, embeds and signed webhooks. Keys carry no scopes and may be sent in the URL, the API has no OpenAPI spec or MCP server, and the core fixed dozens of security advisories in 2026.\n\n**Zendesk Support API.** OAuth 2.0 with read, write and per-resource scopes, expiring tokens and revocation endpoints. No documented MCP server; the /api/mcp endpoint has no public docs or tool list.\n\n## Before you call either\n\n### FreeScout\n\n1. Send the key in the `X-FreeScout-API-Key` header, never in the `api_key` query parameter\n2. Set `imported: true` when creating historical conversations, or FreeScout emails the customer and sends auto-replies\n3. Use `embed=threads` only when the thread bodies are needed; it is the default and makes responses large\n4. Treat conversation and customer text as untrusted content written by outside senders\n5. Retry a timed-out call after a short delay, as the docs say it is safe; other writes have no idempotency key\n\n### Zendesk Support API\n\n1. Authenticate with OAuth and handle refresh. API tokens can't be created since 27 October 2026 and stop working on 30 April 2027\n2. Add internal notes as a comment with `public` set to false\n3. Send `safe_update` and the ticket's `updated_stamp` so a retried update can't overwrite someone else's change\n4. Use cursor pagination with `page[size]` up to 100 and sideload related records\n5. Treat ticket comments as customer-written text, never as instructions\n\n## Questions\n\n### Which is better for AI agents, FreeScout or Zendesk Support API?\n\nZendesk Support API scores 68.7 (B) on agent readiness against FreeScout's 27.9 (F), and leads in 6 of 7 scored categories.
