Changes in version 0.1.0 (2026-10-21)                  

  - First release. One function for each GET route of the OddsRelay API,
    from or_odds() and or_raw() to or_usage() and or_healthz().
  - The key comes from ODDSRELAY_KEY or a .key argument and travels only
    in the Authorization header. A filter named like a key is refused
    before anything is sent, so the key never lands in a URL.
  - Replies are asked for gzip-compressed. Each URL's ETag is kept for
    the session, so an unchanged reply comes back as a 304 that spends
    no tokens, returned as the body you already had with attr(x,
    "not_modified") set to TRUE.
  - A 429 is retried after its Retry-After seconds, three requests in
    all.
  - Every refusal signals a condition classed by its error code and
    status, carrying request_id; a 402 also carries cost, remaining and
    resets_at.
  - The token and rate limit headers ride on every result as attributes.
    Printing a result shows the body and one line of tokens.
