Prescription price research

Access and contract

Use only the three read-only GoodRx price routes listed in reference/endpoints.md. The optional bundled helper is the only shell command this skill asks to run; its allowlist rejects every other route and it accepts GET requests only. When invoked, it reads CRAWLORA_API_KEY and sends it as an x-api-key header over HTTPS to api.crawlora.net; it reads TMPDIR only to choose a temporary config location. The key is not sent to GoodRx. The helper writes a mode-600 curl config under TMPDIR and removes it when the command exits. It does not enumerate environment variables or files, install software, or run with elevated privileges. Run it only for a requested price comparison; successful requests can consume credits. Check application code as well as HTTP status, stop on authentication errors, back off on 429, and retry a transient upstream failure once. Preserve source URLs, identifiers, and collection times.
