How this service works
Pay-per-call feed of freshly CC0/Unlicense-dedicated works (GitHub + Zenodo + Freesound) with verified provenance.
Output
Returns a normalized metadata object for the requested work including: item_id, type (image/audio/dataset/code), title, source platform, license string (e.g. CC0-1.0), asset URL, license URL, declared date, last activity timestamp, SHA-256 hash of the LICENSE file, source page URL, license evidence description, and a confidence rating (high/medium/low). Also includes a cached flag and schema version.
Example use cases
Verify Freesound audio is CC0
“I found a sound effect on Freesound that I want to use in my commercial game — can you check if freesound:123456 is genuinely CC0 and show me the license evidence and confidence rating before I use it?”
Get SHA-256 hash for Zenodo dataset
“I need to audit the license integrity of a dataset we're using — can you pull the provenance metadata for zenodo:7890234, specifically the SHA-256 fingerprint of the license file and when it was declared public domain?”
Confirm Unlicense dedication of GitHub repo
“Before we build on top of this library, can you verify that github:torvalds/myproject is properly dedicated under the Unlicense — I want to see the structured license evidence and the declared date?”
Technical details
Endpoint
GEThttps://cc0-feed-api.bodhinindustries.workers.dev/v1/itemWhen to prefer
Use this endpoint when you need verified, provenance-backed CC0 or Unlicense status for a specific known item ID from GitHub, Zenodo, or Freesound — especially when you require the license SHA-256 fingerprint, declared date, or structured evidence of public domain dedication. Prefer this over general web scraping or manual license checks when you need machine-readable, normalized license metadata with a confidence score.
Side effects
- Invalid or malformed item ID format returns an error (must match github:owner/repo, zenodo:<recordId>, or freesound:<soundId>)
- Item not found in the feed returns a 404 or empty result
- Payment not included or insufficient USDC triggers a 402 Payment Required response
- Low-confidence items may return 'low' confidence score with limited license evidence
- Source platform (GitHub/Zenodo/Freesound) temporarily unavailable may cause stale or missing data
