LyricPatch

Public pricing and signup-free connection instructions. No charge or account needed. A client handles human Stripe checkout or x402 and private credentials; this tool does not spend, create a customer, or receive wallet secrets.

Create/recover signup-free Stripe checkout for $1.99 / 40 credits; does not pay. Require explicit user authorizations. Keep X-LyricPatch-Session privately saved in transport headers. Give the returned message/link to the human; they pay on Stripe. No wallet or website signup needed. Retry with the SAME session, not a new purchase.

Check the privately connected signup-free session after human payment. No charge. Poll at least five seconds apart. Only active means credits/access are confirmed. The same session header can then run the editing tools; no credentials enter chat.

Find a phrase in YOUR supplied timed words; no ASR, external call or charge. Supply text/start_seconds/end_seconds for each word, from your own audio analysis. Timing is not verified by LyricPatch. Preview before generating; ask which occurrence when ambiguous. Do not invent a transcript/timestamps.

Prepare a private MP3 upload (100 MB / 15 minutes max). PUT bytes to returned URL. Use the returned headers, with no LyricPatch Authorization header on the storage request. This only reserves an upload; follow with create_project and ingest_project.

Read edits, generations, original/preview playback, and available downloads. Links are private and short-lived. Ready download links do not spend credits.

Save a 0.1–6-second selection, not a paid generation. Samples use source sample_rate. Choose anywhere including zero. At most 32 non-overlapping edits per project. Next set original/corrected and replacement words with update_edit.

Optionally find words in only a selected 0.1–6-second clip. Never the entire song. Poll get_transcription for results; check transcription against what you hear. Manual lyric entry works without this step.

Get a fixed expiring quote without spending. Cost is ceil(seconds) per edit. max_credits is the user's authorized ceiling. Quote binds current lyrics/selections; changing an edit requires a new quote. Pass its id to generate_changes to spend.

SPENDS the quoted credits and starts async generation. Requires authorized quote. Returns batch/job IDs. Poll status; never resubmit with a new key on timeout. A genuinely new version needs a new quote and may spend again.

Prepare a credit purchase, without paying yet. 40=$1.99,100=$4.99,400=$14.99,1000=$29.99. Gives an account-bound pay_url. An authorized x402 wallet client POSTs to that URL, reads PAYMENT-REQUIRED, then retries with PAYMENT-SIGNATURE for USDC on Base mainnet. Never send wallet private keys to this tool. Browser Stripe checkout is also available.
