DeepSeek API Pricing — KeyoAPI Rates & Official Context

This page puts current KeyoAPI sell rates for DeepSeek V4.1 Flash, V4.1 Flash 1017 snapshot, V4 Flash, and V4 Pro 0813 next to typical official list context — one OpenAI-compatible key.

DeepSeek API Pricing is a model-family pricing lane on KeyoAPI — a prepaid AI API gateway where one Bearer key and one wallet ($1 = 500,000 quota units) cover chat, speech, vision, OCR and video models.

Prototype on gift-credit models, then meter DeepSeek on the same key

To prototype on the same key, use catalog free IDs on the gift-credit models page — gift-credit IDs that bill at dedicated gift-credit rates from your one-time $10 new-user credit (fair-use rate limits) — including deepseek-v4.1-flash-1017:free and DeepSeek-Prover-V2-7B:free. When you meter DeepSeek chat, switch model= to deepseek-v4.1-flash, deepseek-v4.1-flash-1017, deepseek-v4-flash, or deepseek-v4-pro-0813 without changing base URL or auth — those are separate IDs, not one upgrade ladder. Free-path vs pricing detail for Flash: the deepseek-v4-flash model page.

Cheapest current-generation DeepSeek API rate on Keyo

The earlier snapshot deepseek-v4-flash-0731 sits at ~$0.09 / $0.17 per 1M in/out, the standard current-generation DeepSeek Flash lane is deepseek-v4.1-flash at ~$0.14 / $0.56 per 1M in/out, and its October 17 snapshot edition deepseek-v4.1-flash-1017 sets the cheapest current-generation unit rate at ~$0.02 / $0.06 per 1M in/out. deepseek-v4.1-flash-1017 is the recommended default for batch, classification, and agent loops unless long-context limits dominate.

The other rows are separate products, not rungs on a ladder: deepseek-v4.1-flash-1017 at ~$0.02 / $0.06 (October 17 CED snapshot), deepseek-v4-flash at ~$0.44 / $1.32 (legacy catalog string), deepseek-v4-flash-0731 at ~$0.09 / $0.17 (earlier snapshot), and deepseek-v4-pro-0813 with its alias deepseek-v4-pro at ~$0.14 / $0.29 each. So "cheap" here is a task choice, not a tier you upgrade through.

Cost math: 50M input + 10M output tokens/month on deepseek-v4.1-flash ≈ $7.00 + $5.60 ≈ $12.60 (or ≈ $1.00 + $0.60 ≈ $1.60 on the -1017 snapshot). The same mix on deepseek-v4-flash (~$0.44 / $1.32) ≈ $22.00 + $13.20 ≈ $35.20. Confirm live rates on the full pricing list.

Rates and how to call

Compare DeepSeek rates across official platforms, aggregators, and a multi-model API. KeyoAPI is the third option — OpenAI-compatible base URL, prepaid balance, and Gemini/Whisper/OCR on the same key when DeepSeek is only part of the stack.

Indicative Keyo sell rates above come from the live Keyo catalog on the pricing page. Confirm each ID on the pricing page before volume contracts. For details on free prototyping with DeepSeek V4 Flash versus metered pricing, see the guide at the deepseek-v4-flash model page (also covers deepseek-v4.1-flash as the cheaper high-volume Flash when you want a different catalog row).

How to call: POST https://www.keyoapi.xyz/v1/chat/completions with Authorization: Bearer YOUR_KEY and model set to the DeepSeek ID you want — Flash and Pro are different products.

For Gemini rates, see the Gemini API pricing page. For free prototyping, open the gift-credit models page. Side-by-side planning: the model comparison page.

curl https://www.keyoapi.xyz/v1/chat/completions \
  -H "Authorization: Bearer $KEYO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"deepseek-v4.1-flash","messages":[{"role":"user","content":"Hello"}]}'

Get started in five steps

1. Create an account — new users receive $10 of gift credit for prototyping.
2. Create an API key in the console.
3. Point your OpenAI SDK at https://www.keyoapi.xyz/v1 with the model ID from this page, or call the dedicated REST path from the API handbook.
4. Track spend in the console Wallet — $1 equals 500,000 quota units, and gift credit burns before recharged balance.
5. Set a per-key spending cap before wiring production traffic.

A verified first call is the acceptance test for the setup: the response should carry the payload shape documented in the handbook, the Wallet ledger should show a deduction in quota units (500,000 units = $1), and repeated calls should deduct linearly at the listed rate. Any mismatch usually means the model ID or endpoint is wrong — check both against the pricing list before debugging client code.
