Free DeepSeek Proxy for Janitor AI: Setup and Fixing 429 Errors

A DeepSeek proxy for Janitor AI is not a network proxy, and getting that straight up front saves you hours of confusion. It is an LLM backend: you point Janitor AI at DeepSeek's API, either directly or through OpenRouter, using three pieces of information (a proxy URL, an API key, and the exact model name) so DeepSeek writes the character replies instead of Janitor's built-in model.

The rest of this guide is the setup, the exact values to paste, and the fix for the 429 quota errors that send most people looking for help. We run HProxy, an actual network proxy service, so we will also be honest about where our kind of proxy does and does not fit here.

Two different things share the name "proxy"

On Janitor AI, "proxy" means a reverse proxy: a relay that forwards your chat messages to an external LLM API and sends the model's reply back. It changes which brain answers you. It does not change your IP address or your location.

A network proxy (a residential or datacenter IP that routes your traffic) is a completely different tool. It will not make Janitor talk to DeepSeek, and swapping your IP will not fix a quota error. Keep the two ideas separate and the whole process gets easier. If you want a wider look at the backends people wire into Janitor, see our roundup of the best free Janitor AI proxy setups.

The three fields you actually fill in

Janitor AI moves its settings around between updates, so the labels shift. Underneath, you are always filling in three things:

• Proxy URL: the API endpoint, a full URL that ends in /chat/completions.
• API Key: the secret key from whichever provider you signed up with.
• Model Name: the exact model string. It is case sensitive and must match the provider's spelling precisely.

Get any one of these wrong and you get an error instead of a reply. Most "it won't work" reports come down to a typo in the model name or a URL missing the /chat/completions path.

Option A: DeepSeek through OpenRouter (used to be free, now pennies)

OpenRouter is an API aggregator. One key gives you dozens of models behind a single OpenAI-compatible endpoint. For a long stretch it also carried a free DeepSeek variant, and that free slug was the classic no-cost Janitor AI plus DeepSeek setup you will still see quoted in older guides.

That free DeepSeek route is gone. In 2026 OpenRouter retired the deepseek/...:free slugs, so DeepSeek through OpenRouter is now paid. The saving grace is how little you pay: DeepSeek V4 Flash runs about nine cents per million input tokens, so a heavy night of roleplay costs a few cents. If you specifically want a free model and do not care that it is DeepSeek, OpenRouter still lists :free models from other providers, so filter its models page for the free tag and pick one, just know it will not be DeepSeek.

Steps for the DeepSeek-on-OpenRouter route:

1. Go to openrouter.ai and sign up (Google or GitHub login works).
2. Open the Keys page and create a new key. It starts with sk-or-v1-.
3. Add a little credit, since DeepSeek is no longer free here. A couple of dollars lasts a very long time at these rates.
4. In a Janitor AI character chat, open the API settings and choose the proxy / custom option.
5. Paste these values:
   • Proxy URL: https://openrouter.ai/api/v1/chat/completions
   • API Key: your sk-or-v1- key
   • Model Name: deepseek/deepseek-v4-flash
6. Save and send a test message.

One catch: DeepSeek's model ids rotate as it ships new versions, and OpenRouter tracks them (deepseek/deepseek-v3.2 and other variants come and go). If a model name stops resolving, open OpenRouter's models page, filter for DeepSeek, and copy the current id. The deepseek/ provider prefix stays; the version after it moves.

Option B: DeepSeek's own API (cheapest and most stable)

For the cheapest, steadiest route, go straight to the source. DeepSeek's own API skips OpenRouter's small markup, costs a few cents for a heavy day of roleplay, and has no free-tier daily cap to slam into.

Steps:

1. Go to platform.deepseek.com and create an account.
2. Add a small balance (a few dollars lasts a long time at DeepSeek's rates).
3. Create an API key. It starts with sk-.
4. Paste these values into Janitor AI:
   • Proxy URL: https://api.deepseek.com/chat/completions
   • API Key: your sk- key
   • Model Name: deepseek-v4-flash
5. Save and test.

Use deepseek-v4-flash for roleplay. It is DeepSeek's fast general model: natural and good at staying in character. The old deepseek-chat name that older guides list was just this model's non-thinking chat mode. Avoid the reasoning mode (what the retired deepseek-reasoner alias selected), because it emits a separate chain-of-thought stream that some chat frontends handle badly and render as odd or empty-looking replies. One dated heads-up from DeepSeek's own docs: the deepseek-chat and deepseek-reasoner alias names are being retired on 2026-07-24 in favor of explicit ids like deepseek-v4-flash, so paste the explicit id and you will not get caught when the aliases stop resolving.

If https://api.deepseek.com/chat/completions returns an error in your setup, try https://api.deepseek.com/v1/chat/completions. Both are valid. The /v1 is there only for OpenAI-SDK compatibility and has nothing to do with the model version.

OpenRouter vs DeepSeek direct, side by side

Both routes cost money now that DeepSeek's free OpenRouter slug is gone. The trade is the aggregator convenience of OpenRouter against the lower price and steadier limits of going direct.

Fixing the 429 errors

A 429 is the HTTP status for "Too Many Requests." Your request was valid, but you tripped a rate limit and the server refused to answer. Now that DeepSeek itself has left OpenRouter's free tier, a 429 usually means one of two things: you are running one of OpenRouter's remaining free (:free) models and hit its cap, or you are on a shared key where everyone is filling the same bucket.

OpenRouter's published free-tier limits still shape those caps in two layers. OpenRouter adjusts the exact numbers over time, so treat these as the shape of the rule rather than gospel:

• A per-minute cap of 20 requests per minute on free (:free) models. Spam the regenerate button and you hit this in seconds.
• A per-day cap that depends on your lifetime credit: under 10 credits ever purchased gives 50 free requests per day, and once you have bought at least 10 credits (about $10) the daily allowance jumps to 1000.

There is a third cause too: at peak hours the shared capacity for a popular free model gets congested, and OpenRouter throttles it even when you personally are under your own cap.

Here is how to clear a 429, roughly in order of effort:

1. Wait sixty seconds. The per-minute limit resets fast. If you were rapid-firing regenerates, just slow down.
2. Stop hammering regenerate. Every regenerate is a fresh request against your quota. Read the reply, then decide.
3. Add $10 of credit to OpenRouter. This is the single biggest fix. It moves you into the higher daily tier and, in practice, ends most free-tier 429 complaints. The credit is still yours to spend; you are not forced to burn it.
4. Switch to a less congested free model. If your current :free model is throttled at peak, another provider's :free model on OpenRouter may answer. This is a temporary patch, not a cure, and it will not be DeepSeek.
5. Move to DeepSeek's own API (Option B). There is no free-tier daily cap there. You pay cents and the quota 429s simply stop.

Notice that none of these fixes involve changing your IP. That is the honest headline: a 429 is tied to your API account, not your network location, so a network proxy cannot fix it.

The other errors you will hit

429 gets the attention, but a few others show up constantly:

• Network error / failed to fetch: usually a malformed Proxy URL (missing the /chat/completions path), a provider outage, or a browser hiccup. Recheck the URL character by character, then retry.
• 401 Unauthorized: a bad, revoked, or mistyped API key. Regenerate the key and paste it fresh, with no leading or trailing spaces.
• Empty or blank reply: often the reasoning mode (the old deepseek-reasoner alias) returning only its thinking stream, an over-long context, or a content filter. Switch to deepseek-v4-flash and trim the chat history.
• Insufficient balance: DeepSeek direct with a zero balance, or OpenRouter asking you to add credit. Top up.
• Cloudflare or region errors: the provider is geo-blocking your location, or your network is blocking the endpoint. This is the one case where a real proxy earns its keep, covered next.

When a real network proxy actually matters

Here is the honest scope for the tool we actually sell. A network proxy will not fix quota errors, and it will not connect DeepSeek to Janitor for you. It matters in exactly one situation: the API endpoint is blocked before your request ever reaches it.

That happens when DeepSeek or OpenRouter is unavailable in your country, or when a school, office, or ISP network filters the domain. Route the API call through a proxy in an allowed region and the block disappears, because the request now arrives from a permitted location. For a low-stakes reachability fix like this, a free proxy can genuinely be enough.

Two honest caveats before you grab a random free IP. Most free proxies are datacenter IPs that die within minutes to hours (across 47 million of our own checks, only a small fraction work at any given moment), so test before you rely on one. And free proxies carry real trust tradeoffs, which we break down in are free proxies safe, so never route an API key you care about through an IP you do not trust.

For quota errors, fix the account. For reachability, fix the route. Do not mix the two up.
