NSFW Content Generation API — text, image, audio in one synchronised bundle

Q: How do I authenticate?

Bearer token in the Authorization header. Generate keys from your dashboard — sandbox for testing with sample persona sets, production with rate limits and credit metering. Keys are revocable and support per-key IP allowlists.

Q: How does the bundle work?

Send a prompt plus optional persona_id, voice_id, image_lora_id and modality flags. The orchestrator dispatches the LLM, image model and TTS in parallel, binds them via persona_id, and returns JSON with text, image URL and audio URL. Webhook fires for async batches.

Q: What's the rate limit?

Shared-fleet default is 20 concurrent bundles per key and 50K bundles per 24h. Volume tiers lift both. Dedicated pipelines have no hard cap — limited by your GPU cluster and configured queue depth. Batch submission supports up to 200 bundles per request.

Q: What if one modality fails?

Partial-failure retry preserves successful modalities. If the image generates but TTS fails, only TTS re-runs and you receive a credit refund for the failed modality. You don't pay for redundant regeneration of the text or image.

Q: How does persona consistency work?

persona_id binds a voice profile (TTS voice_id), an image LoRA (character face/style), and a personality profile (LLM system prompt + memory). All three modalities reference the same persona_id, so the character whose voice you hear is the same character whose face you see across all calls and scenes.

Q: Can I generate long-form stories?

Yes — submit a story arc or chapter outline; the API generates chapter-by-chapter text + scene image + narration audio with consistent characters across chapters. Branching dialogue trees are supported with choice-state carried between scenes.

Q: Is the API 2257-compliant?

We provide per-bundle content hashes, optional CSAM pre-filter on prompts, post-generation perceptual hash and 2257 record stubs. You remain the 2257 custodian for your business, but our exports make audit conversations survivable. Generated content depicts fictional adult characters by design.

Q: Can I get a dedicated pipeline?

Yes. Dedicated multi-GPU clusters (H100 + A100 mix) start at $7,500/mo with custom persona hosting, sub-3s bundle SLA, dedicated model routing and 24/7 on-call. Talk to sales for a quote tailored to your throughput targets.

Q: Can I toggle modalities per request?

Yes — same endpoint supports text-only, image-only, audio-only, or all three. Useful for incremental generation (story first, then scene image, then narration) or for cost-optimised pipelines that don't always need all three modalities.

A single endpoint that orchestrates NSFW chat LLM + image diffusion + TTS in parallel and returns a synchronised bundle: story text, scene image, character voice. Built for adult content pipelines — long-form story generation, branching script writing, character backstories and scene-by-scene media. Persona_id keeps voice, image LoRA and personality consistent across calls. From $0.02 / bundle.

TL;DR

Endpoint: POST https://api.nsfwcoders.com/v1/content/bundle — orchestrates LLM + image + TTS in parallel; returns synchronised JSON with text, image URL and audio URL.

Pricing: from $0.02 / bundle (entry text+image+audio), itemised per modality; volume tiers and dedicated pipelines available.

SLA: <4s bundle p95 latency on shared fleet, 99.9% uptime with multi-region failover; partial-failure retry preserves successful modalities.

Overview

Stop stitching three APIs into one brittle pipeline

Building an adult content pipeline today usually means calling a chat LLM, then piping output into an image API, then piping image+script into a TTS API — three round-trips, three error modes, three bills, and zero guarantee the voice matches the character the image depicts. Our NSFW Content Generation API collapses that into one endpoint: send a prompt and a persona_id, get back synchronised text + image + audio.

The orchestration layer runs the LLM, image diffusion and TTS in parallel, binds them via a shared persona_id, and returns a bundle. Story scripts stay in character across scenes; image LoRA stays consistent across shots; voice stays consistent across clips. Partial failures retry only the failing modality — your successful image isn't regenerated because the TTS endpoint timed out.

Who uses it: companion apps generating in-chat image+voice messages from a single prompt, content studios producing synchronised story+image+audio for adult audiobooks and visual novels, roleplay marketplaces bundling character intros, and affiliate funnels generating complete landing-page content bundles (story + hero image + voiceover) in one call.

What makes it different: it's not three APIs with a client-side glue layer — it's one orchestration engine with shared persona state. The character whose voice you heard in scene 1 is the same character whose face you see in scene 50. The credit-metered bundle pricing makes it cheaper than calling three separate endpoints, and the partial-failure retry model means you don't pay for redundant regeneration.
