feat(catalog): add Krea image and video generation

[ironman5366]

Summary

• List Krea (krea) as an AI-generation API-key provider: Authorization: Bearer <key>, https://api.krea.ai, free probe GET /jobs?limit=1.
• Curate 11 endpoints: the free job poll (video-gen.task.status), five image routes (Krea 2 Turbo, Krea 2 Large, FLUX.1 [dev], FLUX.1 Kontext [dev], Nano Banana Pro) and five video routes (Seedance 2.5, Veo 3.1 Fast, Wan 3.0, Hailuo 2.3, MiniMax H3 Max Turbo). Five join existing per-model rows (image-gen.gemini-3-pro-image.generate, video-gen.seedance-2-5.generate, video-gen.veo-3-1-fast.generate, video-gen.wan-3-0.from_text, video-gen.hailuo.from_text); five Krea-hosted models are proposed as new per-model keys.
• Every price is read from the machine-readable rate card in the OpenAPI document (x-krea-pricing per operation, source: rate_card_api). Dollars per completed job, so every row is platform-eligible; platform_key_krea slot added in config.py (enabling it is your ops call).
• Test-list additions, a neutral "K" lettermark, and the AI-generation comparison test extended for the new shared rows.

Contact: support@krea.ai (Krea is the vendor; this PR was raised by Krea's growth team.)

Eligibility

• Self-serve keys: workspace owners/admins mint them at https://www.krea.ai/settings/api-tokens. API access is enabled per workspace; a new workspace that does not see the option contacts support@krea.ai.
• Key rides in the Authorization header (Bearer <key>).
• Free probe: GET /jobs?limit=1 lists the caller's own jobs and costs nothing.
• Pricing: https://www.krea.ai/features/api (per-model), plus the per-operation rate card embedded in https://api.krea.ai/openapi.json (x-krea-pricing). Billing model: prepaid USD API balance, debited per completed job; failed and cancelled jobs are free; an empty balance answers HTTP 402.
• Docs with example values: https://www.krea.ai/docs/developers/introduction and https://www.krea.ai/docs/api-reference (also https://www.krea.ai/docs/llms.txt).
• OpenAPI 3.1 at a stable URL: https://api.krea.ai/openapi.json (115 paths). Happy to help with an ingest_krea() extended tier.

Probe (live 2026-09-15 21:40 UTC)

• Bogus key GET https://api.krea.ai/jobs?limit=1 → HTTP 401 {"message":"Unauthorized"} (same body on /usage, /styles, /assets, /node-apps, and on a bogus POST /generate/image/krea/krea-2/medium-turbo; a request with no header answers the same).
• Valid key → HTTP 200 {"items":[…],"next_cursor":…}.

Self-verification ledger (2026-09-15)

Meter: Krea's own API-debit ledger (gpu_time_transactions.api_debit_microdollars, pass_type='api', one DEBIT row per completed job), read from Krea's warehouse replica by job id. The API exposes no per-call charge field or balance route; the dashboard's API-balance card is the customer-visible view of the same ledger. No verified: stamps and no example files in this PR.

Total metered: $1.491620 for the ten generations. All ten jobs completed (6 s to 5 min 18 s) and returned one URL each under result.urls. Every DEBIT row has api_otc_portion_ms = 0, so the whole charge came from the prepaid API balance.

Rate-card note: the marketing page https://www.krea.ai/features/api rounds and lags the per-operation x-krea-pricing card (it shows Flux at $0.04 and Flux Kontext at $0.04; the card and the meter say $0.007 / $0.021). The YAML follows the card, and the card was confirmed by the meter on 9 of 10 rows.

Full-surface map (115 OpenAPI paths, 2026-09-15)

Catalogued (11): GET /jobs/{id}; POST /generate/image/krea/krea-2/medium-turbo, /generate/image/krea/krea-2/large, /generate/image/bfl/flux-1-dev, /generate/image/bfl/flux-1-kontext-dev, /generate/image/google/nano-banana-pro; POST /generate/video/bytedance/seedance-2-5, /generate/video/google/veo-3.1-fast, /generate/video/alibaba/wan-3.0, /generate/video/minimax/hailuo-2.3, /generate/video/minimax/h3-max-turbo.

Excluded (reason):

• Image, 22 more routes (/generate/image/*: Krea 2 Medium, Flux 1.1 Pro / Ultra, Nano Banana, Nano Banana 2 / 2 Lite, Ideogram 2 Turbo / 3, Seedream 4 / 5 Lite / 5 Pro, Luma UNI-1, Muse Image, ChatGPT Image, Grok Imagine 2 / 2 Edit): priced on the card but no shared shelf yet — extended-tier candidates from the OpenAPI. openai/gpt-image-2, gpt-image-2.5-flare, gpt-image-2.5-sunburst, bytedance/seededit, qwen/2512, runway/gen-4-image, z-image/z-image: no price on the rate card yet, so they cannot carry a cost block (GPT Image 2 / 2.5 would otherwise join the existing shared rows — we will add them when the card covers them).
• Video, 30 more routes (/generate/video/*: Wan 2.1 / 2.2 / 2.5, Flux 3 Video, Seedance 2.0 / 2.0 Fast / 2.0 Mini, Veo 2 / 3 / 3 Fast / 3.1 / 3.1 Lite, Kling 2.5 / 2.6 / 3.0 / o1, LTX 2.3 / 2.5 Fast / 2.5 Pro, Ray 2, H3 Max / H3, Hailuo / Hailuo 02, Runway Gen-4 / 4.5, Vidu Q3, Grok Imagine / 1.5): priced, same extended-tier reasoning; the curated set keeps the cheapest tier (H3 Max Turbo), the flagship (Seedance 2.5) and the three cross-provider joins. flux-video-edit, seedance-1.0-pro, seedance-1.0-pro-fast, gemini-omni-flash / 1.1, h3-max-camera-controls: no price on the card.
• Enhance, 16 routes (/generate/enhance/*: Krea Enhance, Krea Legacy, Topaz family, SeedVR2, Flux Upscale, Ruby): no price on the rate card for any of them, so no cost block is possible today.
• 3D, 10 routes (/generate/3d/*) and audio, 5 routes (/generate/audio/*): no 3d-gen / audio-gen platform slug exists in capabilities.yaml, and platforms cannot be proposed from a provider file. Five 3D routes are priced ($0.021–$0.40 per request); if you add the slugs we will curate them.
• GET /jobs, DELETE /jobs/{id}, GET/POST/DELETE /assets*, GET/PATCH /styles*, POST /styles/train, /styles/{id}/share/*, /node-apps*, POST /export/3d: own-account management, uploads, LoRA training and user-defined workflows — not comparable generation jobs. (POST /assets is a free way to host inputs; treg host covers the same need.)
• GET /usage: own-account compute-unit report, enterprise-plan entitlement only, and it excludes direct-API jobs — not the API meter.

Test plan

• uv run --frozen python scripts/catalog_validate.py → OK — 102 provider file(s), 3346 endpoint(s), 0 error(s), 0 warning(s)
• uv run --frozen --with pytest-xdist pytest -n auto -q → 4,098 passed, 8 skipped (after regenerating the plugin skill's provider count with scripts/build_plugin.py and recording Krea's documented 402 in capacity/signatures.py)
• Maintainer live bogus-key POST /connections/token and catalog_verify.py krea with an independent key — email the contact above for a funded test key
