How this service works
crypto-intelligence verdicts (CIN) + creative-judgment/QC + post-gen media-ops — agent-facing
Output
Returns a verdict object containing a harmony grade or creative quality score based on the provided tension, harmony, and pitch feature values. The exact schema is a generic object, likely containing numeric scores, letter grades, or pass/fail verdicts for the audio asset's harmonic characteristics.
Example use cases
Post-generation audio QC pipeline
“I just generated a music track and got back these features: tension 0.4, harmony 0.9, pitch 0.55. Can you grade its harmony and tell me if it meets creative quality standards before I publish it?”
Filtering low-quality AI music outputs
“I have a batch of AI-generated audio clips and I want to filter out the ones with bad harmonic quality. Start with this one: tension 0.8, harmony 0.3, pitch 0.65 — what's the harmony grade?”
Comparing creative tension across music variations
“I made two versions of a track. Version A has tension 0.2, harmony 0.7, pitch 0.5, and version B has tension 0.6, harmony 0.6, pitch 0.7. Can you grade both for harmony quality so I can pick the better one?”
Technical details
Endpoint
POSThttps://lucky-x402.onrender.com/x402/harmony-grade?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need automated creative quality control or harmonic grading on post-generated audio or music assets described by tension, harmony, and pitch features. It is particularly useful in AI media pipelines where generated audio needs a pass/fail verdict before publishing or downstream processing. Prefer it over generic ML classification APIs when your use case specifically involves musical/harmonic feature grading.
Side effects
- Missing required 'features' object returns validation error
- Missing tension, harmony, or pitch sub-fields may cause computation failure
- Out-of-range feature values (e.g. outside 0-1) may return unexpected results
- Payment failure or insufficient USDC balance blocks the request
- Service unavailable on Render free tier cold starts causing timeout
