Frequently Asked Questions
Everything you need to know about deAPI pricing
Every request is billed dynamically, with the metric chosen to match each task: resolution × steps for images, characters for speech, tokens for embeddings, duration with optional resolution for video, hours for transcription, output characters for OCR, and per-image rates for background removal and upscaling. There are no subscriptions, no monthly minimums, and no hidden fees — you fund a prepaid balance and each successful inference deducts its exact cost. Before any job, you can call the matching /price endpoint to preview the precise cost for the model and parameters you plan to use.
Yes. Every new account receives $5 in free credits the moment you sign up — no credit card, no upfront commitment. That balance is enough to test most models extensively, generate hundreds of images, transcribe several hours of video, or prototype a complete AI pipeline. Your account starts on the Basic tier with conservative rate limits designed for testing; making any payment upgrades you to Premium with no waiting period.
Inference is routed through a globally distributed GPU network rather than concentrated in a few hyperscale data centers, which removes most of the infrastructure markup baked into traditional cloud pricing. We also serve highly optimized open-source models — many of them quantized (INT8, FP8, NF4) and distilled — so each request uses fewer GPU seconds without sacrificing output quality. The combined effect can deliver up to 20× lower inference cost for comparable workloads.
deAPI uses Stripe for secure card payments and supported local methods. You can either make one-off top-ups (with preset amounts of $10, $25, or $50) or enable automatic top-ups, which recharge your balance whenever it drops below $2 — perfect for production workloads that can't afford to fail mid-job. For B2B customers needing custom invoices, larger commitments, or tailored billing terms, our team arranges individual agreements; just reach out to support.
The Basic tier offers conservative rate limits (typically 1–10 RPM depending on the endpoint) ideal for testing. The moment you make any payment via Stripe, your account upgrades to Premium with 300 RPM across all endpoints and unlimited daily requests — instantly, with no application process. For high-volume production needs beyond Premium, dedicated capacity, or enterprise terms, our team can set up bespoke arrangements with volume discounts.
OCR is billed per 1,000 output characters extracted, at a baseline of $0.00928 per 1,000 chars for 1024×1024 source images. The practical effect is that you only pay for what the model actually reads — a small product image with about 20 characters costs roughly $0.000186, while a full book page (~1,500 characters) lands around $0.014. Empty or near-empty images stay almost free.
Nanonets OCR S is well-suited for invoices, receipts, business cards, forms, ID documents, contracts, and general business paperwork. It handles printed text reliably and performs well on moderately legible handwriting. Both single-photo objects (product labels, signage) and full document pages are supported, with input images in JPG, JPEG, PNG, GIF, BMP, or WebP formats up to 10 MB.
Yes. The OCR endpoint supports a format parameter with text and json options — json returns a structured response useful for invoice parsing, receipt digitization, and form processing pipelines that feed directly into accounting systems, CRMs, or databases. You can also pass an optional language hint to improve accuracy when you know the document's primary language up front.
Yes — the model handles multi-language extraction in a single request, so a Polish invoice with English column headers, or a Spanish receipt with French marketing copy, parses cleanly without specifying a language up front. Best accuracy is achieved on Latin, Cyrillic, and CJK scripts on well-scanned documents; handwritten or stylized fonts may require slightly higher-resolution inputs to maintain quality.
Yes. For workloads exceeding 100,000+ images, our team arranges custom volume pricing tailored to your processing pattern — particularly relevant for document digitization platforms, accounting integrations, and compliance archiving systems.
