No status page, SLA, security.txt or idempotency key was found, and the privacy policy says prompts and uploads may be used to train models.\n\n**Soundverse API.** Songs with vocals, instrumentals, stems (2, 6 or 12), SFX and remix behind one endpoint. No status page, changelog or security.txt.\n\n## Before you call either\n\n### MusicGPT API\n\n1. Send the key as the raw `Authorization` header value. The docs show no `Bearer` prefix\n2. Budget two songs for each music request. `POST /v2/MusicAI` returns two versions and the price is per song\n3. Save `task_id` and poll `GET /v1/byId` with `conversionType`, or set `webhook_url`. Music AI V2 sends up to seven webhooks a request\n4. Pass `model` explicitly. The default is `v6`, and `voice_id` or `vocal_only` forces `v6` whatever is passed\n5. Do not retry a create blindly after a timeout. No idempotency key is documented, so a retry may bill again\n\n### Soundverse API\n\n1. Always set `Idempotency-Key` on creates, so a retry after a 429 doesn't bill twice\n2. Retry only errors with `retryable: true` (`RateLimited`, `DependencyUnavailable`). 401 and 403 won't fix themselves\n3. Pass `license` explicitly. The default is 1, royalty-free, which doesn't cover sync or distribution\n4. Fetch audio through `GET /v1/files/{file_id}/download`, then poll `GET /v1/generations/{id}` or open `/stream` for progress\n\n## Questions\n\n### Which is better for AI agents, MusicGPT API or Soundverse API?\n\nMusicGPT API scores 45.9 (E) on agent readiness against Soundverse API's 41.9 (E), and leads in 5 of 7 scored categories. Soundverse API leads on agent ergonomics.\n\n### Which is cheaper for music generation, MusicGPT API or Soundverse API?\n\nMusicGPT API, at $0.035 per call against $0.07 per call for Soundverse API. These are the vendors' published prices for the job.\n\n### Do MusicGPT API and Soundverse API need an API key?\n\nBoth need an API key.\n\n### Can an agent call MusicGPT API and Soundverse API without installing anything?\n\nYes. MusicGPT API has a hosted endpoint at https://api.musicgpt.com/api/public and Soundverse API at https://apiv2.soundverse.ai/v1.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/musicgpt-vs-soundverse.json, and with the fewest tokens: https://www.anchorterminal.com/compare/musicgpt-vs-soundverse.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"musicgpt\", \"b\": \"soundverse\"}`.
