A shop your AI agent can use on its own

No demo call, no sales email, no dashboard. INKFLOW exposes its whole catalogue over the Model Context Protocol and a plain REST API, so an autonomous agent can browse, price, buy, track and download without a human in our loop or yours.

What an agent can buy

Complete books from 45,000 to 900,000 words — or one continuous story past 2,000,000 words as a multi-volume epic under a single continuity ledger (a 2,138,487-word canon is already delivered), multi-volume series with automatic continuity bibles, manuals and technical specifications, in 22 natively-written languages - and royalty-free ULTRA LoRA packs for AI video from £9.

Commercial terms an agent can rely on

Firm quotes before commitment. Stripe payment links (we never see card details). Idempotency-Key support, so a retry can never double-charge. HMAC-signed webhooks with retry and jitter. Token-gated download URLs. Delivered or refunded — no third outcome: work is checkpointed, recovers automatically, and a non-delivery triggers a full automatic refund.

The shelf, live

46 ULTRA-trained identity models on the shelf right now, 39 more in training — and the ad never lies about it: the capabilities JSON carries a loraLibrary section generated from the studio’s live training ledger on every request. Each entry flips from IN TRAINING to ULTRA TRAINED by itself the moment its file verifies at rank 64. Buy the growing pack once and every later addition is free, forever.

Why buy models here and not a marketplace

Measured, not claimed: the sale gate reads the rank out of the .safetensors header — a file that is not rank 64 cannot be listed. Trained deep: 5,000 steps at rank 64 where marketplace models sit near 1,500–2,500 at rank 16–32. Curated data: ~40 DINOv2-screened candidates per subject, drift discarded, and the trainer refuses to run on an incoherent set. Safe commercially: every face is an original synthetic person — no real-person likeness, no brand marks. Casts that act together: characters, sets and props trained to share shots — a persistent world, not a grab-bag of faces.

Proof before payment

One COMPLETE ULTRA LoRA is free: download Dariusz Kwiatkowski-Osei (436 MB, no signup, perpetual royalty-free commercial licence) and judge the standard yourself. His six-angle card — including the shots that usually break a character LoRA — is in the capabilities JSON under freeUltraLora.card, and the rank-verification snippet is in the readme. If it does not read 64, we are lying.
