Add WRouter provider

[Jaykebc1]

Adds WRouter, an OpenAI-compatible AI gateway.

Provider

• Endpoint https://wrouter.ai/v1 (OpenAI-compatible), env WROUTER_API_KEY, @ai-sdk/openai-compatible.
• Logo uses currentColor only.

Models

12 headline models referencing canonical base_models (Anthropic Claude, OpenAI GPT, Google Gemini).

Pricing

Prices are WRouter's own list prices, taken from WRouter's public pricing API (https://wrouter.ai/api/pricing) and shown on https://wrouter.ai/pricing . As a gateway, WRouter sets its own USD rates, so some differ from the upstream providers' list prices (e.g. gemini-2.5-pro output is $5/M on WRouter). Values verified: claude-sonnet-5 $3/$15, claude-opus-4-8 $5/$25, gpt-4o $2.5/$10, gpt-4o-mini $0.15/$0.60, matching the underlying models.

Reasoning controls

• GPT-5 / mini / nano: OpenAI reasoning_effort (minimal|low|medium|high), passed through the OpenAI-compatible endpoint.
• Claude / Gemini: left as reasoning_options = [] — reasoning-control mapping through the OpenAI-compatible gateway is not yet documented per-model; will add once verified against WRouter's API docs.

Action items

• [high] [violation] providers/wrouter/logo.svg:3 - Check: New providers must ship a logo that uses currentColor with no fixed size or hardcoded colors. Why: The SVG hardcodes brand colors (#0C2E26, #5EF1A0) on strokes and fills, so it will not adapt to light/dark themes and fails the contribution logo guidelines (merge blocker). Action: Rewrite providers/wrouter/logo.svg to use currentColor only (no hardcoded fills/strokes), keep a square viewBox, and avoid fixed width/height.
• [high] [violation] providers/wrouter/models/claude-haiku-4-5.toml:1 - Check: Provider models with reasoning = true must declare reasoning_options for that inference surface. Why: These entries inherit reasoning = true from their base_models but omit reasoning_options: claude-haiku-4-5, claude-opus-4-8, claude-sonnet-5, gemini-2.5-flash, gemini-2.5-flash-lite, gemini-2.5-pro, gpt-5, gpt-5-mini, gpt-5-nano. Omission is not an audited empty list and blocks merge. WRouter is @ai-sdk/openai-compatible at /v1; comparable OpenAI-compatible gateways author explicit options or [] when no caller control is verified. Action: For each of those nine models, add provider-verified reasoning_options (with API syntax comments if nonstandard), or set reasoning_options = [] when the model reasons but no WRouter control is verified. Cite WRouter docs/API evidence in the PR body for any non-empty options.
• [low] [possible mistake] providers/wrouter/models/claude-haiku-4-5.toml:4 - Check: Data-changing PRs should cite direct provider pricing/docs mapped to claims. Why: The PR body says pricing comes from “WRouter's public pricing” and underlying providers but does not link a WRouter pricing/docs URL or map rates to each model, so the new [cost] values cannot be reviewed from the PR alone. Action: Add first-party links (e.g. WRouter pricing and/or model/API docs) in the PR body and note what each URL supports for the listed costs.

• [critical] [violation] providers/wrouter/logo.svg:3 - Check: New-provider logo must use currentColor with no hardcoded colors. Why: The SVG hardcodes brand colors (#0C2E26, #5EF1A0) on strokes/fills, so it will not adapt to light/dark themes and fails the contribution checklist blocker. Action: Rewrite logo.svg to use currentColor only (no fixed hex fills/strokes), keep a square viewBox, and omit fixed width/height.
• [high] [possible mistake] providers/wrouter/models/gpt-5.toml:2 - Check: reasoning_options must match WRouter’s OpenAI-compatible request surface, not a blanket toggle. Why: All nine reasoning models claim [{ type = "toggle" }], but same-model peers on comparable OpenAI-compatible gateways (e.g. OpenRouter, LLM Gateway, FastRouter) expose effort for GPT-5/mini/nano, and Claude/Gemini peers commonly use effort and/or budget_tokens rather than toggle-only. A universal toggle is unsupported by the PR and contradicts those surfaces. Action: Verify each control against WRouter’s docs/API (exact request fields). Replace incorrect options with verified controls (and adjacent # API: ... comments where needed), or use reasoning_options = [] when no caller control is verified; cite the evidence in the PR body.
• [low] [possible mistake] .pr-review/pull-request.json (PR body) - Check: Data-changing PRs should cite direct provider pricing/docs mapped to claims. Why: The body asserts WRouter USD pricing and cross-checks but links only the homepage/docs, with no pricing URL or per-claim mapping (e.g. gemini-2.5-pro output 5 vs common upstream 10). Action: Add first-party pricing (and reasoning-control) links and state what each supports.

Action items

• [medium] [possible mistake] providers/wrouter/models/claude-sonnet-5.toml:5 - Check: Provider cost must match WRouter's actual list price for this model ID. Why: input = 3 / output = 15 matches Anthropic Claude Sonnet 4.5, not Claude Sonnet 5 (2 / 10 in providers/anthropic and OpenRouter). That looks like a wrong-generation copy rather than intentional WRouter markup. Action: Confirm against WRouter's pricing page; if this is Sonnet 5, correct to the listed rate (likely 2/10 if pass-through), or keep 3/15 only with a first-party citation that maps those figures to claude-sonnet-5.
• [medium] [possible mistake] providers/wrouter/models/gemini-2.5-pro.toml:6 - Check: Provider cost must match WRouter's actual list price for this model ID. Why: output = 5 is half the Google/OpenRouter Gemini 2.5 Pro output rate (10); input 1.25 matches upstream. No other catalog entry uses 5 for this model, so this needs verification. Action: Confirm on WRouter's pricing page and correct if wrong, or cite the exact WRouter rate that supports output = 5.
• [low] [possible mistake] providers/wrouter/provider.toml:1 - Check: Data-changing PRs should cite direct first-party pricing/docs mapped to claims. Why: The PR asserts WRouter list pricing and cross-checks vs upstream, but does not link a pricing or model catalog URL, so the two divergent rates above cannot be reviewed from the PR alone. Action: Add a first-party WRouter pricing (or models) URL in the PR body and note which models/rates it supports.
