- `GET /v1/eol/{product}/{cycle}`: one cycle, $0.001.
- `POST /v1/eol/check`: up to 50 product versions in one call, $0.01.
- `GET /v1/eol/image?image=node:18-alpine3.19`: a container image, its runtime and base OS, $0.005.
- `POST /v1/stack/check`: up to 50 product versions, 50 packages (purls) checked against OSV.dev and 100 CVEs checked against CISA KEV in one call, $0.012.
