Gift-Credit AI Models — No Credit Card Required

KeyoAPI offers gift-credit models callable with your complimentary credits. Billed at dedicated gift-credit rates; gift credits are used first, with any shortfall charged to your recharge balance. New users get $10, and each successful invite earns $3. Register a key and set model to any ID in the table below.

The gift-credit catalog is a prototype lane of :free IDs on KeyoAPI, a prepaid AI API gateway: each bills at each model's dedicated gift-credit rate from gift credits first — new accounts start with $10, invites add $3 — and any shortfall falls through to the recharge balance on the same wallet.

Get started in five steps

Create an account — new users receive $10 of gift credit for prototyping.
Create an API key in the console.
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.
Track spend in the console Wallet — $1 equals 500,000 quota units, and gift credit burns before recharged balance.
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.

Built for prototypes, demos, CI smoke tests, and eval harnesses. For production QPS, switch to metered (paid) model IDs on the same base URL.

Browse by family in the table above (Other, DeepSeek, GLM, ASR, Keyo, TTS). Start with gift-credit models — no credit card required; move to metered IDs when you need higher throughput or additional models.

Gift-credit rules (read before you ship)

Price: gift-credit IDs are billed at dedicated gift-credit rates (see table above and full pricing list). Gift credits are used first; any shortfall is charged to your recharge balance.
Dedicated gift rates: gift-credit catalog IDs (with :free suffix) draw from promotional credits ($10 welcome credit, +$3 per invite) and operate on dedicated gift-pool rates. For maximum cash unit economics on standard wallet top-ups, call the un-suffixed base twin IDs on the full pricing list.
Complimentary credits: calls draw from your gift-credit balance (new users: $10; per successful invite: $3). When it runs out, top up to keep calling.
Fair use: gift-credit traffic has rate / concurrency limits. Limits can tighten under abuse. Do not treat gift-credit IDs as an unlimited production SLA.
Availability: some :free IDs may be added or removed from the catalog. Check Model Square before hard-coding.
Catch (honest): you get real capability with gift credits; you do not get paid-tier priority or guaranteed throughput.

FAQ

Can I use gift credits without a credit card?

Yes — gift-credit IDs are callable with your complimentary credits (new users: $10; per invite: $3) with no credit card required to start. Fair-use rate limits apply.

What's the catch?

Fair-use rate limiting and lower priority. Exact RPM can change; if you need predictable limits, use metered (paid) IDs.

Gift-credit vs paid?

Gift-credit IDs use your complimentary credits first (with fair-use limits). Paid IDs are token- or request-metered with higher priority — preferred for production.

Can I use it in production?

You can. For anything user-facing or latency-sensitive, we recommend metered IDs. Gift-credit models are ideal for prototypes, demos, CI smoke tests, and eval harnesses.

Why one hub page?

One page keeps every gift-credit ID and its limits in one place — bookmark it; we update it when the catalog changes.

When you outgrow gift-credit models

Same key, switch model= only. Gift-credit IDs are chat and speech lanes — video generation has no free tier and bills per generated second:

CosyVoice3 API — hosted async TTS when you need production throughput
TTS API hub · Voice cloning · IndexTTS-2
DeepSeek V4 Flash pricing — metered Flash after gift-credit prototypes
Kimi K3 API key — draft on gift-credit IDs, then kimi-k3
Duix Avatar API — talking-face after TTS · Compare rates
Video generation APIs — per-second billing from ~$0.02/s: Seedance 2.0 · MiniMax-H3 · FLUX.3 · Wan 3.0 · Agnes · enhance / subtitle erase
