V1 is now retired 🏁​

The V1 API has reached the end of the road. Every request to a /v1/* route now returns 410 Gone. V2 has covered everything V1 did for a while now, so this is the moment we switch it off for good.

What's changed​

/v1/* returns 410 Gone 🚫​

Any call to a V1 path gets a terminal response, so old integrations fail fast instead of hanging:

{
	"statusCode": 410,
	"message": "The v1 API has been deprecated. Use the v2 API.",
	"docs": "https://docs.tengr.ai/v2/"
}

The V1 reference in these docs is now a single deprecation notice rather than a full endpoint list. The V1 entry stays in the version selector so old links still resolve to an explanation.

V2 is the default 🧭​

Unversioned requests now resolve to V2. If you call a path without a version prefix, you land on the V2 surface automatically. The auth model is unchanged: send an API key as Authorization: Bearer sk_....

The V2 reference is fully refreshed 📚​

These docs now track the current V2 surface end to end, including every generation family and the full third-party model catalog added since the last changelog. Each endpoint carries an up-to-date request and response shape.

Moving from V1​

If you still have a V1 integration, the switch is small:

• Swap Supabase session-token auth for an API key.
• Change your paths from /v1/... to /v2/....
• Provide a webhook URL to receive the finished artwork, or poll it by id.

Head to the V2 API reference for the full surface.

v2.2.0 is here 🧭​

A minor release with two behaviour changes worth flagging upfront, an 8-day retention window on generated artworks, two fixes, and a top-to-bottom refresh of these docs.

What's changed​

nsfw flag now consistent across models ⚖️​

Every artwork endpoint now follows the same rule: nsfw: true means allow NSFW output, and nsfw: false (the default) suppresses it. Selena and Selena Variete used to be inverted, so if you were sending nsfw: true to those models expecting suppression, flip it to nsfw: false.

Default promptMode flipped to servitor 🪄​

The default promptMode changed from seer (AI prompt enhancement) to servitor (raw prompt) across Selena, Selena Variete, Hamilton, and Quantum. To keep prompt enhancement, pass promptMode: "seer" explicitly.

8-day retention on generated artworks 🗓️​

Artwork records, their input images, and their generated images are all removed 8 days after creation. After the window, GET /v2/artworks/:id returns 404 for that ID. If you need to keep an image around long-term, download it within those 8 days.

Fixes 🔧​

• GET / no longer returns an empty route list. Under NestJS 11 and Express 5, the metadata endpoint's internal router lookup broke silently. Restored, so the routes field is populated again.
• Selena Variete now honours promptMode. The field used to be ignored.
• NSFW suppression now applies cleanly on Selena and Selena Variete. It was previously being applied twice.

Documentation rework 📚​

We've also taken the docs through a top-to-bottom pass:

• A new Introduction page that gives you a real overview of what the API does (image generation, image editing, image utilities, and the Textcraft LLM) and how to authenticate.
• Section order is now stable and meaningful: General, Artworks, Selena, Quantum, Hamilton, Photo Pilot, Textcraft, Style DNA, Organizations.
• Every endpoint summary and description has been rewritten in plain language so you can tell what a route does at a glance.
• The version selector locks to V2 (current) and V1 (deprecated), with a deprecation banner across every V1 page.
• Internal-only endpoints no longer appear in the docs or in the GET / route list, keeping the public surface tight.

Getting started​

If you're on v2.1.0, the only changes you might feel at the wire level are the two behaviour flips above (nsfw semantics, promptMode default). Everything else is additive or transparent.

v2.1.0 is here ✨​

A week after v2.0.0, this is a focused follow-up. The big things are truly non-blocking artwork creation, a model selector on Face Refiner, structured error shapes, the Infinity styles working in image-to-image, and a stack of security upgrades.

What's new​

Truly non-blocking artwork creation ⚡​

Every v2 artwork-creation endpoint backed by the in-house pipeline (selena, selena-variete, hamilton, photo-pilot, face-refiner, face-swap, segmentation, depth-map, detailer-upscaler, quantum, remove-background) used to return 202 only after prompt building and the upstream dispatch finished. Both can take long enough to overrun client HTTP timeouts.

Now the artwork is persisted with status: STARTING and the 202 returns in milliseconds. Prompt building (which can chain 3-4 LLM calls) and the upstream dispatch run in the background. If anything fails after the 202, the artwork lands in FAILED and the failure flows out through your webhook, not a synchronous 5xx.

Zod validation errors still return 4xx synchronously, same as before.

Face Refiner accepts a model selection 👤​

POST /v2/artworks/face-refiner now takes an optional model parameter. Leave it off and the request fans out to all available Tengr.ai face-refining models (the default behaviour). Pass a specific model name and the request runs only on that one. This brings Face Refiner in line with how Selena and Selena Variete handle model selection.

Structured error responses 📋​

Every v2 endpoint now returns errors in a consistent { status, message } shape, both on GET /v2/artworks/:id and on outbound webhooks. The v1 wire shape is frozen, so older integrations see the same errors they always did.

Infinity styles in image-to-image 🌀​

The seamless Infinity styles (infiny-weave, infiny-pattern, infiny-flow) now work in Selena Variete, not just in text-to-image. Useful when you want tileable backgrounds or repeating patterns starting from an existing image.

Hamilton style tuning 🎚️​

A handful of Hamilton styles got their default colour grade softened, so generations look less heavily stylised out of the box.

Security updates 🛡️​

A round of dependency upgrades to keep the stack current and clear the latest security advisories. No action needed on your end.

Performance and reliability​

• Better CPU utilisation on multi-core machines via optional worker processes.
• A self-healing job that picks up any artwork whose status update or webhook didn't arrive and finishes it correctly, so no generation silently stays stuck.
• A unified error vocabulary across all generation models, so the same kind of upstream failure looks the same from your side regardless of which model produced it.

Getting started​

If you're already on v2.0.0, this release is backward compatible. The async improvements speed things up on their own. The new options are opt-in.

For request examples and migration notes, see our API documentation.

v2.0.0 is here 🚀​

v2 is a major rework of the public API. We've split the surface into two versions side by side: a frozen v1 (the v1.4.0 set, on Supabase JWT auth) and a new v2 surface on API-key auth with two-dimensional access control, async generation with HMAC-signed webhooks, and a wider catalogue of in-house generation endpoints. Existing v1 integrations keep working unchanged.

What's new​

Versioning split 🪟​

Every route that shipped at v1.4.0 keeps its /v1/... form. The same routes also exist at /v2/... under API-key auth. Anything we introduced after v1.4.0 (Quantum, Selena Variete, Face Refiner, Face Swap, Segmentation, Depth Map, Detailer Upscaler) is v2-only. Migrate when it suits you.

API key auth with scope and domain 🔐​

v2 keys carry two dimensions. Scope is a strict hierarchy: admin > manager > generator. Domains are the feature areas the key can reach: artworks, style-dna, textcraft, or * for all of them. Both have to pass on every request.

Org admins manage keys through POST /v2/organizations/:orgId/api-keys (create) and DELETE /v2/organizations/:orgId/api-keys/:keyId (revoke). The full key is returned once at creation, so store it somewhere safe.

New in-house generation endpoints 🎨​

• Quantum for text-to-image with high coherence and detail, plus its own styles and aspect ratios.
• Selena Variete for image-to-image variations, with a catalogue of processing modes.
• Face Refiner for cleaning up portrait detail.
• Face Swap for replacing a face from a source image onto a target.
• Segmentation for masks from prompts or points.
• Depth Map for grayscale depth output.
• Detailer Upscaler for sharpening fine details with optional upscaling.
• Upscaler at /v2/artworks/upscaling with the same Selena-backed upscaler.

Async workflows with signed webhooks 📤​

Every v2 generation endpoint returns 202 Accepted immediately with an artwork ID. The final result lands at the webhook URL you supplied with the request, signed with HMAC-SHA256. Each delivery carries Tengrai-Timestamp and Tengrai-Signature headers, computed over ${timestamp}.${rawBody} using your organization's webhook secret. You can rotate the secret through POST /v2/organizations/:orgId/webhook-secret.

v1 endpoints stay synchronous and unsigned, so existing integrations don't have to change.

Style DNA goes async in v2​

The image-producing Style DNA endpoints under /v2/style-dna/* now return 202 and complete via webhook. Specifically: generate, generate/asset, edit, edit/style-aware, remove-background, and generate-anchor. The two sub-second LLM-only endpoints (generate-style-options and refine-prompt) stay synchronous.

For generate/asset with backgroundMode: transparent, the server chains generation and background-removal automatically. Your webhook fires once, on the final result.

Getting started​

The v2 reference includes request examples, webhook setup, and the auth flow. Head to our API documentation for the full v2 surface.

If you're on v1, your existing integrations keep working at /v1/.... Migrate when the new endpoints, webhooks, or auth model fit your needs.
