    # generated event. Anything else, including a server-side tool item such as web_search_call and
    # any frame not on that list, releases the stream immediately. On the SSE transport the lines that
    # are not `data:` frames - comments, `event:` lines, blank separators - are held alongside them.
    # The hold is bounded by a frame budget and a 1 MiB byte budget, not by wall-clock time: an
    # upstream that trickles frames holds the response headers for as long as the client will wait.
    # Why: the upstream smuggles `server_is_overloaded` rejections *inside* an HTTP 200 stream,
    # right after those handshake events, instead of returning 503 on the wire. Buffering them
    # keeps the downstream response headers uncommitted long enough to transparently retry on
    # another credential. Only overload/rate-limit rejections trigger failover; every other terminal
    # failure is still delivered in-stream exactly as before. One pre-existing behaviour is worth
    # knowing, because this option makes the window it lives in much longer: if the stream ends while
    # the bootstrap is still holding, the attempt ends instead of the error reaching the client, and
    # whether another credential is then tried depends on how it ended. A clean end with no terminal
    # event is request-scoped on SSE, so nothing else is tried; a websocket close, or a transport error
    # such as a dropped connection on either transport, is not, so the request may be retried on
    # another credential. None of that is new, but before this option the hold ended at the first
    # keepalive, so it was rare; now it can span the whole reasoning phase.
    # Trade-off: response headers are delayed until generation starts. Because heartbeats are held
    # too, the delay now ends at the first generated token rather than at the first heartbeat. The
    # budget bounds how much is held, not how long: 48 SSE lines, which measures out as 15 heartbeats
    # of the three-line event:/data:/blank shape, 23 of a two-line ": keepalive" comment followed by
    # its blank separator, or 47 of a bare ": keepalive" with no separator - one short of the obvious
    # division, because the rejection frame's own event: line comes out of the same budget before its
    # data: line is parsed. An upstream that sends the rejection as a bare data: line with no event:
    # line gets the round number instead. At a 10s upstream heartbeat that is 150s, 230s or 470s of
    # uncommitted response headers depending on the framing the upstream picks, all of it past nginx's
    # 60s default proxy_read_timeout, so raise the timeouts in front of the proxy before enabling this.
    # Those seconds bound what the buffer holds, not when the response headers are committed. Headers
    # are committed on the first chunk the downstream translator actually produces, so for a format
    # that renders the handshake as nothing - Chat Completions and Gemini do - they stay uncommitted
    # past the budget, until the first generated token. That is not specific to the budget: any frame
    # that releases the buffer has always behaved this way.
    # The websocket transport spends the same 48 differently - one per message read, whether the loop
    # holds it or skips it, with no framing to divide by - so there it is 48 heartbeats, about 480s.
    # Two cases no budget covers: a websocket peer that sends only ping frames, which the library
    # answers inside the read call, leaving only the 5 minute websocket read deadline; and an upstream
    # that stops mid-line on SSE, where the scanner never returns and only the request context ends the
    # wait. Neither is made worse by this option - with it off the same stalled line stalls the
    # conductor instead, which waits on the same context - but a client-side request timeout, not
    # proxy_read_timeout, is what bounds them.
    # Default: false
    stream-bootstrap-buffering: false
    # Optional maximum duration to hold back uncommitted response headers during bootstrap buffering.
    # When set (e.g. "20s"), if the time ceiling is reached before the first generated token,
    # the stream is released to the client and further in-stream overloads are delivered rather
    # than failed over. This bounds how long trickled heartbeats or early empty frames can delay
    # response headers before streaming begins.
    # Recommendation: If your CPA is deployed behind a reverse proxy with a strict read timeout
    # (e.g. Nginx default proxy_read_timeout 60s or Cloudflare 100s timeout), setting this to "20s"
    # is strongly recommended to guarantee headers commit well before proxy timeouts while retaining
    # a comfortable 20s window to fail over early scheduling overloads.
    # Note: The timeout check is evaluated as upstream frames arrive; it never aborts the upstream
    # connection. Downstream headers are committed as soon as the downstream translator emits chunks
    # (for formats that render handshake/heartbeats, headers commit immediately on release; for

# API-key upstreams are separate from access.api-keys (client authentication).
# Each provider contains named groups: one base-url, shared settings, and a keys list.
# Add another group for another endpoint; base-url belongs to the group, not a key.
# Shared settings retain their provider-specific validation and meaning.
# Missing/null per-key overrides inherit the group value, then the runtime fallback.
# Explicit false, 0, empty strings, and empty collections override inheritance when
# supported by the field. Map/list overrides replace the inherited value as a whole.
# Negative request-retry values retain the global fallback; weight belongs to each key.
# An empty proxy-url falls back to requests.proxy-url; direct bypasses proxy settings.
# Shared provider defaults belong to upstream; OAuth-only features remain under oauth.providers.
# Keep differing legacy policies in separate groups or preserve them as key overrides.
# Uncomment the api-keys root and only the provider examples you want to configure.
# Replace placeholder keys/URLs before using them.

#           #                         rotating access tokens. "oauth-cli" is a legacy alias.
#           #
#           # count_tokens keeps the native model/messages/tools shape for every origin, including

#           #
#           # CCH: the billing block may carry a per-request cch hash. CPA emits it exactly where
#           # Claude Code does, which is api.anthropic.com (first-party) and Vertex only. An opt-in
#           # on any other gateway (including Kimi) still sends the billing block, but without cch,
#           # so a per-request hash cannot bust that gateway's prompt cache. api.anthropic.com
#           # strips the block itself (0 tokens, no cache impact). Kimi drops the whole block by
#           # default and keeps it, unsigned, after an explicit fingerprint opt-in.
#           # A real Claude OAuth credential always signs, on every upstream: a downstream Claude
#           # Code pointed at CPA cannot produce that value itself.

# END API KEY EXAMPLES

# OAuth/file-backed credentials. Token material stays in the credential store.
oauth:
  # Authentication directory (supports ~ for home directory)
  auth-dir: "~/.cli-proxy-api"

  # Core auth auto-refresh and manual refresh-all worker pool size (OAuth/file-based auth token refresh).
  # When > 0, overrides the default worker count (16).
  # auth-auto-refresh-workers: 16

  # Global OAuth model name aliases (per channel)
  # These aliases rename model IDs for both model listing and request routing.
  # Supported channels: vertex, aistudio, antigravity, claude, codex, kimi, xai, meta.
  # NOTE: These aliases do not apply to any of the upstream groups under api-keys.
  # NOTE: Because aliases affect the merged /v1 model list and merged request routing, overlapping
  # client-visible names can become ambiguous across providers. For strict backend pinning, use
  # unique aliases/prefixes or avoid overlapping names.
  # You can repeat the same name with different aliases to expose multiple client model names.
  # Optional per-entry fields:
  #   fork: true                  # keep the upstream model and also expose the alias as a separate client-visible model
  #   display-name: "Model Name" # override the human-readable name shown in model catalogs
  #   force-mapping: true         # rewrite upstream response model fields back to the client-visible alias (example below uses antigravity only)
  # Per-auth OAuth aliases can also be stored in an OAuth auth JSON file as "model_aliases".
  # Legacy "model-aliases" credentials remain supported and are normalized at load time.
  # They apply only to that selected auth and take precedence over global aliases for the same client-visible alias.
