AI music generation via API

Best for

  • Integrating AI music generation into applications
  • Programmatic soundtrack and audio content creation
  • Comprehensive REST API with endpoints covering the full music generation workflow

Watch out for

  • 15-day asset storage limit
  • Content policy strictly prohibits NSFW generation
  • Credit costs vary by model and are subject to change

Overview

Udio API is a REST interface for programmatic access to AI music generation models. It provides developers with endpoints for creating original music tracks, extending existing compositions, generating cover artwork, and producing timestamped lyrics — all through standard HTTP requests authenticated via API keys.

API Capabilities

The core generation endpoint at POST /api/v2/generate accepts prompts and parameters to produce AI-composed music. Supporting endpoints handle track extension, cover image generation (at 1 credit per image), timestamped lyrics, and audio upload with cover generation. A callback endpoint allows asynchronous task notification, and the task status and query credits endpoints provide operational visibility into usage and generation progress.

Pricing and Credits

The service operates on a credit-based system with monthly, yearly, and pay-as-you-go tiers. According to the vendor's documentation, different AI music models consume varying amounts of credits, and users are advised to consult the credit guide before making generation requests. New users receive free starter credits upon registration, and the platform offers daily check-in credits as an ongoing incentive.

Operational Constraints

Generated assets are retained for 15 days before removal. Failed API calls attributable to system errors may result in automatic credit restoration rather than cash refunds. The refund policy explicitly excludes purchases associated with Terms of Service or Content Policy violations.

Content Moderation

The platform maintains a zero-tolerance policy toward prohibited content. NSFW, sexual, adult, pornographic, and child exploitation material are strictly forbidden, with violations resulting in immediate account termination and potential law enforcement reporting. The privacy policy documents collection of usage logs — including generation requests, API calls, errors, and timestamps — and states that anonymized usage data is analyzed to improve features and reliability.

Developer Integration

API keys are created and managed through the dashboard. The service is owned by AI Music API or its licensors, with all software, interfaces, designs, and trademarks protected by intellectual property laws. For developers building in the AI Developer Tools space, Udio API slots in as a music-generation component alongside tools like ExtWise and CodingPlan.

Score anatomy

The dimensions behind the editorial score, each with its judgment note. AI Readiness and GEO Score are platform assessments generated by VibeLaunch after submission.

Information quality

API documentation covers all endpoints with endpoint paths, credit costs, and operational parameters. Privacy, terms, refund, and content policies are all separately documented and accessible.

7.5
Contextual

Seven distinct documentation pages cover API reference, pricing, dashboard usage, privacy, terms, refunds, and content policy.

Ease of use

Standard REST API with API key authentication and a dashboard for key management. Free starter credits and daily check-ins reduce the initial friction for developer evaluation.

7.0
Contextual

API keys are created through a dashboard interface; documentation provides endpoint references and credit consumption guidance.

Feature depth

Seven distinct API capabilities span generation, extension, cover art, lyrics, upload, status checking, and async callbacks — covering the full music creation pipeline.

7.8
Contextual

Endpoint list includes generate, extend, cover image, timestamped lyrics, upload and cover, task status, query credits, and callback.

Workflow fit

The async callback pattern and REST design fit standard developer integration workflows. The 15-day asset retention window requires explicit download logic in consuming applications.

7.2
Contextual

Callback endpoint enables non-blocking integration; credit query and task status endpoints support operational monitoring.

Reliability

Automatic credit restoration for system errors is a positive signal, but the 15-day asset retention, variable credit costs subject to change, and promotional pricing introduce operational uncertainty.

6.0
Verify

Refund policy documents credit restoration for system errors; pricing page notes limited-time offers and credit cost variability.

Value

Free starter credits provide a no-cost evaluation path. Multiple pricing tiers offer flexibility, but variable per-model credit consumption and promotional discount timelines make long-term cost forecasting difficult.

6.2
Verify

Pricing documentation lists monthly, yearly, and pay-as-you-go options with bonus credits and limited-time savings.

Scores indicate documented product strength, not a hands-on guarantee.

Agent Readiness

How well an agent can understand this product and reconstruct a documented workflow from its official information.

Automated agent-readiness assessment of https://udioapi.pro: 2 of 22 checks verified across 1 fetched pages.

Decision desk

The questions most worth resolving before you rely on the product or visit its official site.

Credits are deducted per API call when invoking metered features or AI models. Different models consume varying amounts of credits, and costs are subject to change. The documentation provides a credit guide for budgeting before making generation requests.

Generated assets are stored for 15 days. After this period, files are removed from the service. Developers should download and persist assets they intend to keep long-term.

New users receive free starter credits upon registration and can earn additional credits through daily check-ins. These credits can be used to evaluate the service before purchasing a paid plan.

The platform prohibits sexual, adult, pornographic, nude, sexually explicit, or otherwise NSFW content, as well as any content involving child exploitation. Violations result in immediate account termination and potential law enforcement reporting.

Failed API calls due to system errors may result in automatic credit restoration rather than cash refunds. For other refund scenarios, users should consult the refund policy and contact support within 7 days for case-by-case review.
