Pulse account

Get a Pulse account.

Create a Pulse account to get one API key for the REST API and the MCP server. Estimates are free; analysis uses pay-per-use tokens, with optional token packs for repeated workflows.

No minimum. Run analyses for $0.01 or $0.50, no floor.

One key. Use across REST API, MCP, and the landing page.

Token packs. Buy banked tokens for API-key analysis, or use one-off checkout when you do not need an account.

No subscription. Tokens never expire.

Your Pulse account is ready.

Here's your API key. Copy it now; do not paste it into public directories, screenshots, GitHub issues, or shared chats.

Save this key now. Pulse will never show it again — there's no recovery if you lose it. Store it in a password manager or trusted local environment.

The short version

We don't store your audio as user audio. Files are fetched and processed for analysis, then cleaned up after the job.
Your payment details never touch Pulse. Payment entry happens on Stripe's hosted page. Pulse only ever sees Stripe reference IDs and dollar amounts — no card number, no CVV, no billing address, no bank or device token.
We don't track you. No analytics scripts, no third-party tags. The only outbound calls are to Stripe (payments) and Google Fonts (typography).
We do store your account email, banked-token balance, analysis results (BPM number, key, waveform peaks), and Stripe payment-reference IDs — not your submitted audio as user audio, and never your payment method.
You're responsible for the audio you submit. You do not need to own the song, but you must have rights, permission, lawful access, or another legal basis to submit it for Pulse to process.
Money back when we under-deliver. If a job fails or we charged too much for it, we refund automatically.
