No per-number or per-minute price is public, API keys carry no scopes, orders have no idempotency key, and outbound calling needs an approved application. Calls travel over SIP only.\n\n**Twilio Programmable Voice API + MCP.** Twilio APIs SLA at 99.95 per cent for every paying customer, with 10 per cent credits. US outbound at $0.014 a minute, plus $0.0044 for Media Streams or $0.07 for ConversationRelay.\n\n## Before you call either\n\n### DIDWW Voice and Number Management API\n\n1. Send `Api-Key: \u003ckey\u003e` with no `Bearer` prefix, plus `Accept: application/vnd.api+json`, and `Content-Type: application/vnd.api+json` on every request with a body\n2. Set `X-DIDWW-API-Version: 2026-04-16` on each request and read `meta.api_version` in the reply. A header older than the account's version is ignored\n3. Before retrying a timed-out `POST /orders`, list `GET /orders` first. The order is charged to the balance at once and no idempotency key exists\n4. Stay under 20 requests a second per key. On `429` wait before retrying, since no `Retry-After` header is documented\n5. Use `fields[...]`, `filter[...]`, `include` and `page[size]` (default 50, maximum 100) to keep JSON:API replies small\n6. Check `GET /address_requirements` before buying a number. Many countries need a verified identity and address, and the sandbox cannot run identity verification\n7. Create and enable a callback secret in the User Panel before relying on callbacks. Without one nothing is sent, and receivers must verify `X-DIDWW-Signature`\n\n### Twilio Programmable Voice API + MCP\n\n1. Use `\u003cConnect\u003e\u003cStream\u003e` for two-way audio. It blocks further TwiML until the websocket closes\n2. Use `\u003cConnect\u003e\u003cConversationRelay\u003e` when you only want to handle text, and set `interruptible` for barge-in\n3. Trial calls reach only verified numbers in your sign-up country\n4. Retry a 429 with backoff, but check the Calls list before retrying a create that timed out, since there's no idempotency key\n5. Validate `X-Twilio-Signature` on every webhook and websocket upgrade\n\n## Questions\n\n### Which is better for AI agents, DIDWW Voice and Number Management API or Twilio Programmable Voice API + MCP?\n\nTwilio Programmable Voice API + MCP scores 80.4 (A) on agent readiness against DIDWW Voice and Number Management API's 65.1 (B), and leads in every scored category.\n\n### Do DIDWW Voice and Number Management API and Twilio Programmable Voice API + MCP need an API key?\n\nDIDWW Voice and Number Management API needs an API key. Twilio Programmable Voice API + MCP takes an API key or an OAuth sign-in.\n\n### Can an agent call DIDWW Voice and Number Management API and Twilio Programmable Voice API + MCP without installing anything?\n\nYes. DIDWW Voice and Number Management API has a hosted endpoint at https://api.didww.com/mcp and Twilio Programmable Voice API + MCP at https://api.twilio.com/2010-04-01.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/didww-voice-and-number-management-vs-twilio-voice.json, and with the fewest tokens: https://www.anchorterminal.com/compare/didww-voice-and-number-management-vs-twilio-voice.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"didww-voice-and-number-management\", \"b\": \"twilio-voice\"}`.
