digital_human.rs uses url::Url::parse but the crate was only a transitive
dependency, not declared in Cargo.toml, so the lib failed to compile with
E0433. Add the explicit dependency (url 2.x was already in Cargo.lock).
Implement the four Gemini native inbound endpoints so Gemini CLI / Google
GenAI SDKs can point their base URL at the gateway:
- GET /v1beta/models — directory listing in Gemini shape, built from
configured routes (like /v1/models); no upstream call, no billing.
- POST /v1beta/models/{model}:generateContent — non-streaming, routed
through ProxyConductor with failover + usage_logs + billing.
- POST /v1beta/models/{model}:streamGenerateContent — SSE passthrough via
open_stream_with_failover + sse_passthrough_response.
- POST /v1beta/models/{model}:countTokens — metadata call, routed for a
channel but not billed.
Auth accepts the gateway key from ?key= or x-goog-api-key (Gemini
convention) and reuses the downstream-key authorization + limits.
Billing closes the loop: gemini_extract_usage reads usageMetadata
(promptTokenCount / candidatesTokenCount) for non-streaming, and
gemini_stream_usage_from_line feeds the shared StreamUsageAccumulator so
streamed usageMetadata is billed too.
Unit tests cover model:action parsing, usage extraction, the stream usage
parser, and query forwarding (key/alt dropped).
Add Gemini-shaped upstream calls that mirror AQBot's native passthrough
and BoosAPI's /v1/responses forwarding: the model lives in the URL path
(/v1beta/models/{model}:{op}) and the key in ?key=, so the body is sent
verbatim with no model rewrite.
- gemini_base_url / gemini_operation_url normalize the v1beta root and
build {base}/v1beta/models/{model}:{op}?key=...&{extra}, stripping a
leading models/ prefix and handling the no-key case.
- execute_gemini_operation runs non-streaming ops (generateContent /
countTokens) and returns upstream JSON verbatim.
- execute_gemini_stream_response opens streamGenerateContent for SSE
passthrough, enforcing alt=sse via merge_alt_sse.
Unit tests cover URL building and alt=sse merging.
Pre-existing breakage on this branch (introduced by the billing commits),
unrelated to the Gemini work but blocking both `cargo build` and
`cargo test`:
- admin/users.rs imported routes::auth::DEFAULT_NEW_USER_MAX_COST_USD,
which was never defined. Add it to auth.rs as $1.0 (the billing design's
"new users default to $1" starter allowance).
- AppConfig gained `payment` and `pixelle_video` fields but several test
helpers still used struct literals missing them. Initialize both with
Default::default() at each affected test site.
Add GET /api/cli-profiles/templates returning copy-ready config snippets
for pointing common AI clients at this gateway: Cursor, VS Code Continue,
Claude Code, and a generic OpenAI-compatible blob.
Ported from AQBot's list_gateway_templates (a desktop app that hardcodes
localhost:8080). Adapted for server-side use: the gateway origin is resolved
per request — ?base_url= override, then X-Forwarded-Proto + Host (correct
behind a TLS-terminating proxy), then config server.host:port fallback
(0.0.0.0/:: rewritten to 127.0.0.1, matching the comfyui-agent local-base
convention). OpenAI-compatible clients get the /v1 base; Claude Code gets
the bare origin since it appends /v1/messages itself.
Scope guard: this only returns config strings + copy hints. It deliberately
does not rewrite local CLI config files (AQBot's desktop cli_config behavior),
which has no meaning on a server.
New module proxy::cli_profiles::templates holds the snippet content; the admin
handler resolves the origin. Covered by 9 unit tests.
