## Primary collector register

GET https://mytdh.xyz/api/raster-collector-tdh?profile={URL_ENCODED_RASTER_ARTIST_PROFILE}&offset=0&limit=100

Example profile: https://www.raster.art/artist/casey-reas

The response contains a paginated collector register. A 404 with covered=false means no register has been generated yet. Never infer a zero score from an uncovered profile.

## Generate a missing register

POST https://mytdh.xyz/api/raster-collector-jobs
Content-Type: application/json

{"profile":"https://www.raster.art/artist/joe-pease"}

The response is either a cached completed register or a durable background job. Poll its `jobUrl` until `state` is `complete`, then fetch `resultUrl`. Jobs are idempotent for the artist and snapshot day and may take several minutes.

## Interpretation

- The primary score is an artist-specific adaptation of abTDH, not oTDH.
- Each current work contributes uninterrupted days held, weighted inversely by its indexed edition size.
- Results are reported per eligible collector address across the artist's verified Raster-indexed oeuvre.
- It does not use price, sales volume, floor price, reputation, or artistic quality.
- A result is meaningful only with its methodology, snapshot date, and corpus.
