An llms.txt written for agents, with a task-to-endpoint table and webhook payloads, while docs pages are HTML (10). 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). The `/a1/` path, with no changelog found (5 of 15). 18+10+14+9+10+5 = 66.\n- Exotel Voice API + MCP (48): No OpenAPI spec found (0). The listing's llms.txt at developer.exotel.com/llms.txt returns 404, as does /docs/llms.txt, and exotel.com has none (0). Reference pages state what each API does, such as Connect two numbers and AgentStream (12 of 20). Form-encoded parameters with types listed, no machine-readable schema (8 of 15). Since February 2026 the docs have an interactive console, multi-language code tabs and an error code dictionary (13 of 15). Versioned v1 and v3 APIs and a public changelog (15).\n\n### Agent ergonomics: 46elks Voice API +11\n\n- 46elks Voice API (51): Compact JSON responses, and call actions returned as small JSON objects (18 of 25). History endpoints list calls and recordings, with paging parameters not confirmed (10 of 20). Errors carry `error` and `detail` (12 of 20). No idempotency key on `POST /calls` or number allocation (3 of 20). Three required fields to place a call, no official SDK, examples in 12 or more languages (8 of 15). 18+10+12+3+8 = 51.\n- Exotel Voice API + MCP (40): Call detail lists exist, and we didn't confirm page-size or field controls (10 of 25). Pagination and filters not confirmed (10 of 20). Error code dictionary (15 of 20). No idempotency key or safe-retry guidance found (0). No official server SDK on npm or PyPI, only a WebRTC SDK. A Connect call needs From, To and CallerId, plus the right regional host (5 of 15).\n\n### Maintenance \u0026 community: 46elks Voice API +7\n\n- 46elks Voice API (12): No changelog, release notes or dated API change was found, the sitemap's newest blog post is from 2014, and the Swagger file predates Realtime Voice (0). No dated changes in the 90 days from 8 August (0). Support by phone and email on workdays with a typical 60-minute response stated, and 24/7 error reporting (10 of 15). No official SDK (0). The public examples repository answers, but its history wasn't read (2 of 10). 0+0+10+0+2 = 12.\n- Exotel Voice API + MCP (5): The developer changelog's newest entry is a docs upgrade on 2026-02-16, and the newest API entry is Gen AI APIs in January 2026, over 180 days ago (0). No dated entries in the last 90 days (0). Support exists, and the ExotelMCP repo has 30 commits and 5 stars. We didn't sample issue replies (5 of 15). No official server SDKs (0).

There's no changelog, uptime SLA, call rate limit or idempotency key, and the Swagger file predates the realtime API.\n\n**Exotel Voice API + MCP.** Local Indian numbers and DLT and TRAI handling. Per-minute rates and plan prices not published.\n\n## Before you call either\n\n### 46elks Voice API\n\n1. Send numbers in E.164 format, such as +46700000000, or the request fails\n2. Pass `whenhangup` on `POST /calls` to learn when a call ends or fails to connect\n3. Don't retry a call request on a 4xx; retry 5xx with backoff, and check call history first to avoid a second call\n4. Treat caller speech, DTMF and SMS replies as untrusted input, and verify webhook origin\n5. Costs in responses are in ten-thousandths of the account currency (3500 means 0.35)\n\n### Exotel Voice API + MCP\n\n1. Use api.in.exotel.com for India-hosted accounts and api.exotel.com for Singapore-hosted ones\n2. Pass StreamUrl on Calls/connect for a quick outbound voice-agent call\n3.
