Kahoot! vs Learnosity

Kahoot! 45

Read with the hosted lines. status.kahoot.com is an Atlassian Statuspage with component history (20). One incident since 5 August 2026, YouTube video disruptions on 22 September, minor, about six hours (20). No rate limits in the OpenAPI file, and the support guide that might hold them answered our reader with a Cloudflare check (0). No 429 or retry guidance (0). No SLA found; the Master Service Agreement on the trust centre wasn't read (0). The spec is version 0.1.0 with no stability statement, though the enterprise page sells the API as a feature (5 of 10). 20 + 20 + 0 + 0 + 0 + 5 = 45.

Learnosity 75

Read with the hosted lines on the Data API. Statuspage at status.learnosity.com with component history (20). From 1 August to 3 November 2026 the feed lists six entries, Enhanced Math scoring delays in US-East-1 on 11 September, 2 October and 20 October (the last touching the Data API scoring endpoint for about 4 hours 40 minutes), an LTS remapping issue on 8 October, a demos-site maintenance on 21 to 22 October and Item Pools degraded in all regions for about 2 hours 20 minutes on 26 October, so one incident of an hour or more on a core endpoint and the rest regional or partial (10). Rate limits published per endpoint in 5-second windows (15). A 429 with meta.code 42000 and a stated 5-second wait, but no Retry-After header and no idempotency keys for SET and UPDATE (10 of 15). SLA uptime of 99.8 or 99.9 per cent by support tier on the licences page (10). The APIs are generally available, with LTS versions (10). 20 + 10 + 15 + 10 + 10 + 10 = 75.

Kahoot! 58

Read for a closed service. iOS 6.8.0 on 27 October 2026 (30). Three App Store releases in the 90 days, 12, 22 and 27 October (20). A status page, a help centre and sales contact, but no public changelog for the API and the help centre is behind a bot check for us (8 of 15). No SDK or registry entry (0). No package to judge (0). 30 + 20 + 8 + 0 + 0 = 58.

Learnosity 85

Read for a closed service. Developer release log dated 28 October 2026 and v2026.2.LTS on 10 June 2026 (30). Developer builds about every two weeks with dated logs in September and October (20). Release logs per API, support tickets, the Build Aide feedback widget, and SDK repositories with pull requests merged through 16 October 2026 (12 of 15). Current SDKs for Python (v0.3.13, 14 January 2026, commits to 16 October), Node.js (v0.7.3, 2 October 2026) and PHP (v1.2.1), under Apache-2.0 (15). GitHub Actions CI on the Python and Node.js SDKs; the Node SDK removed express from its dependencies in v0.7.3 (8 of 10). 30 + 20 + 12 + 15 + 8 = 85.

Kahoot! 69

OAuth 2.0 client credentials with an opaque bearer token from a Keycloak realm; the client id and secret are issued by Kahoot! and the spec defines no scopes (24 of 30). The API is read-only by design and reaches one organisation's data (16 of 20). Open-ended, word-cloud and brainstorming answers are participant-written text with no guidance on handling it (5 of 15). Enterprise admins get user management and reports, but no per-call API log is documented (4 of 15). security.txt with Expires 2027-10-02, a published disclosure policy without rewards, ISO 27001 certification and SOC 2 Type 2 stated (20). 24 + 16 + 5 + 4 + 20 = 69.

Learnosity 54

A consumer key and secret per consumer, with every request signed server-side and the secret never sent; rotation and revocation are not described on public pages (22 of 30). Access is scoped per consumer and the MCP server is read-only, but no read-only Data API credential or confirmation for session deletion was found (8 of 20). The Data API returns learner responses, which are untrusted text, with no guidance (5 of 15). No per-call audit log for the operator found on public pages (3 of 15). ISO 27001 certificate, CSA STAR, a public HECVAT, EU-US DPF and a FedRAMP Moderate authorisation stated by the CTO, security@learnosity.com and a good-faith research authorisation; no security.txt or paid bounty (16 of 20). 22 + 8 + 5 + 3 + 16 = 54.

Kahoot! 62

Public OpenAPI 3.1.0 at results.kahoot.com/openapi (25). No llms.txt on kahoot.com, 404 on 3 November 2026 (0). Every operation has a one-line description and the schemas describe each answer type, but nothing says when to use an endpoint or what the data window is (12 of 20). Path ids are typed as UUID, limit has a 1 to 100 range and default, 12 enums such as game mode and answer status, and a discriminator on answer type (12 of 15). Twelve example values in the schemas, but responses list only 200, 401 and 403 with no error body (8 of 15). A /v1 prefix and an ApiVersion schema, with no public changelog for the API (5 of 15). 25 + 0 + 12 + 12 + 8 + 5 = 62.

Learnosity 67

No public OpenAPI or similar document was found for the Data API; the reference is help-centre articles, and only the Build Aide MCP server has typed tool inputs, over documentation rather than data (8 of 25). No llms.txt, but the hosted MCP server serves the documentation to agents with source citations (8 of 10). Endpoint articles state what each category is for and when to use the Data API instead of the pre-built APIs (15 of 20). Parameters are typed per endpoint in the articles, read only in part through the JSON API, so partial credit (9 of 15). Troubleshooting articles per HTTP code with the error body, and SDK examples in five languages (12 of 15). Dated LTS versions, release logs per API and developer release logs every two weeks (15). 8 + 8 + 15 + 9 + 12 + 15 = 67.

Kahoot! 66

Eleven compact GET endpoints returning typed JSON (20 of 25). Cursor pagination with limit up to 100 on users, versions and games, and startedSince on games; no field selection (16 of 20). Only 401 and 403 are documented, with no body schema or codes to branch on (6 of 20). Read-only, so every call is safe to retry (16 of 20). One or two path parameters per call and sensible paging defaults, but no official SDK in any language (8 of 15). 20 + 16 + 6 + 16 + 8 = 66.

Learnosity 61

REST endpoints grouped by category, dataset endpoints for bulk reads, and an MCP server with eight compact tools; field selection on Data API responses was not confirmed (18 of 25). Pagination on list endpoints was not read first-hand, so partial credit (8 of 20). Errors carry meta.status, meta.code and meta.message, with a troubleshooting article per code (14 of 20). No idempotency keys; the MCP tools are read-only and say so (6 of 20). SDKs in Python, Node.js, PHP and more handle signing, with few required fields beyond the signature (15). 18 + 8 + 14 + 6 + 15 = 61.

Kahoot! 15

Read with the hosted rule. No x402, MPP or L402 (0). Pro plans are public, $9 to $79 a presenter a month billed annually, but the API is enterprise-only and priced by quote (10). A free account needs no card and Pro has a seven-day trial, but neither reaches the API (5 of 20). Credentials come from Kahoot! to an enterprise organisation, so a person signs the contract and requests them (0). 0 + 10 + 5 + 0 = 15.

Learnosity 10

No x402, MPP or L402 (0). No price published; tiers and support levels are described and a quote comes from sales (0). No free tier or trial for the platform; the demos site runs on a public demos consumer key and the MCP server is free, which is documentation rather than the product (5 of 20). A contract and credentials from Learnosity are needed; only the documentation MCP server is reachable without a person (5 of 20). 0 + 0 + 5 + 5 = 10.
