feat!: add Hostinger Router as an OpenAI-compatible provider (#44863)
* feat: add Hostinger Router as an OpenAI-compatible provider

Adds hostinger_router (https://router.hostinger.com/v1) to the
JSON-configured openai_like providers with chat completions, responses,
messages, and embeddings endpoints, cost-map entries for claude-sonnet-5,
gpt-5.2 and the two text-embedding-3 models (credits converted at
1 credit = $0.01, sourced from the public
https://router.hostinger.com/v1/models catalog), the endpoint-support
matrix, Admin UI add-model form fields and logo, and respx-mocked unit
tests covering all declared endpoints.

Also routes /v1/embeddings for JSON-configured providers that declare it
in providers.json; previously embedding calls for these providers fell
through to LiteLLMUnknownProvider.

* fix(hostinger_router): match prices to the live catalog, drop retired max_tokens, regenerate the endpoint matrix

* fix(hostinger_router): keep api_base detection off, send embeddings headers as HTTP headers, drop generic key fallback

Unprefixed models called with Hostinger's api_base keep their own provider, JSON provider
embeddings no longer borrow OPENAI_LIKE_API_KEY or litellm.api_key, and the openai_like
embedding handler sends extra_headers as request headers instead of in the JSON body

* fix(openai_like): route Hostinger messages and responses per model, keep the configured key header

Native /v1/messages and /v1/responses calls for a JSON provider now also follow the
model's cost-map supported_endpoints, so Hostinger models without the route go
through chat completions instead of a 403. Embedding key headers replace
extra_headers case-insensitively, and pinstripes stops declaring /v1/embeddings.

* fix(openai_like): let embeddings extra_headers override the key's headers as chat does

Embeddings now match chat through the OpenAI SDK, so an extra_headers entry replaces the key's header of the same name in any letter case. The Hostinger capability test checks that the supports_* lookups agree with each cost-map row instead of pinning vendor flags

* fix(openai_like): send numeric embeddings extra_headers as text and keep Hostinger's 1h cache TTL

A config.yaml header like X-Org-Id: 12345 loads as an int, which the embeddings header check rejected with a 500. Int and float values now go out as their decimal text. Hostinger Router accepts and bills a 1h cache_control TTL on /v1/messages, so its provider entry opts into keeping it.

* fix(openai_like): send Hostinger's 1h cache TTL as the 5-minute default so cache writes bill at its charge

* fix(openai_like): route Hostinger natives per model from providers.json, refuse non-text embeddings headers unless drop_params

* fix(openai_like): refuse Host, Content-Length and Transfer-Encoding in embeddings extra_headers unless drop_params

* fix(openai_like): refuse malformed embeddings extra_headers and ignore transport headers

Header names must be HTTP tokens and values printable ASCII on one line, so a
colon in a name or a line break in a value answers 400 unless drop_params drops
it. Host, Content-Length and Transfer-Encoding are ignored, since a 400 for them
sends the call to the deployment's fallback with the same headers.

* fix(openai_like): trim embeddings extra_headers values and drop values HTTP cannot carry

HTTP ignores spaces and tabs around a header value, so values are trimmed
before they are sent. A value that is not printable ASCII on one line after
trimming is dropped with a warning instead of failing the call, since the
proxy adds headers itself from key aliases and forwarded client headers that
the caller cannot fix. A malformed header name or a non-text value still
answers 400 unless drop_params drops it.

* fix(openai_like): ignore hop-by-hop extra_headers and trim line breaks around values

TE, Upgrade, Connection, Keep-Alive, Proxy-Connection and Trailer in
extra_headers are now ignored like Host, Content-Length and
Transfer-Encoding, since litellm builds the request and TE: gzip fails
HTTP/2 while Upgrade makes some upstreams hang. Line breaks at the ends of a
value are trimmed along with spaces and tabs, so a secret read from a file
with a trailing newline is sent instead of dropped. The drop warning now
names the model.

* fix(embeddings): keep one request's extra_headers out of the deployment's headers and ignore Expect

embedding() merged a request's extra_headers into the headers dict it got
from the deployment's litellm_params. The router only shallow-copies those
params, so the merge wrote the caller's headers into the deployment itself,
and later embeddings calls through that deployment sent them too. Build a
new dict instead, and drop the None checks that can no longer be true.

Also treat Expect as a transport header that hostinger_router embeddings
never forwards, and name the model with %r in the dropped-value warning.

* fix(embeddings): keep name and value pairs working in headers and answer 400 for other non-object values

The previous commit merged headers and extra_headers with dict unpacking,
which only takes a mapping, so a list of name and value pairs that
dict.update used to accept now raised a TypeError and the proxy answered
500. Merge through dict() so pairs keep working, and answer 400 for any
other value, or drop it under drop_params, as the litellm convention does
for an unsupported param.

In total litellm runs 1000+ tests

[02/20/2025] Update:

To make it easier to contribute and map what behavior is tested,

we've started mapping the litellm directory in tests/unit

This folder can only run mock tests.
