46elks Voice API 12

didlogic Voice API 38

Release notes dated by month, the newest September 2026 (click-to-call API and WebSocket calls), about 37 to 67 days before this check (20). Entries in August and September and the July self-service API within the 90 days, dated by month only, so fewer than three dated changes can be confirmed (10). Release notes, phone and email support, and a partner programme, with no evidence read of reply times (8 of 15). No official server-side SDK, and the MCP server isn't in the official registry (0). No package to assess (0). 20+10+8+0+0 = 38.

46elks Voice API 47

Graded on the hosted REST and Realtime Voice APIs with the hosted lines. A status page exists, linked from 46elks.com/status on UptimeRobot (20). It draws its data by script from a path its robots.txt disallows, so no history was readable (5). SMS sending speed is documented in the FAQ, but no limit for calls, numbers or WebSocket sessions was found (5 of 15). llms.txt says to retry 5xx with exponential backoff and not to retry 4xx unchanged, with no Retry-After or idempotency for POST /calls (7 of 15). The SLA page commits to support hours and 24/7 error reporting with no uptime figure, and extended SLAs are by sales (0). Voice and Realtime Voice carry no beta label (10). 20+5+5+7+0+10 = 47.

didlogic Voice API 26

Graded on the hosted API and MCP server with the hosted lines. The footer's network status page carries no components or incidents, and no other status page was found (0). No readable incident history (5). Rate limits are given only for recording lookups (one a second, one lookup a minute) (5 of 15). Those endpoints document 429 with Retry-After and X-RateLimit headers, with no backoff guidance or idempotency elsewhere, including number purchases and click-to-call (6 of 15). The site claims 99.999 per cent voice uptime, but no SLA was found in the Terms (0). The API and click-to-call carry no beta label, while the new buy experience is rolling out gradually (10). 0+5+5+6+0+10 = 26.

46elks Voice API 66

Each docs page explains parameters and when webhooks fire, such as voice_start loading only once a call connects (14 of 20). Form-encoded parameters with types in the Swagger file and few enums (9 of 15). Examples in many languages and a JSON error shape, with no error list (10 of 15).

Typed request bodies with required fields and enums in the spec (12 of 15). Examples, a standard error envelope ({"errors":{"base":[...]}}) and 401, 403, 404 and 422 responses on most operations (12 of 15). Paths versioned v1 and v2, and release notes dated by month (12 of 15). 25+10+16+12+12+12 = 87.
