No verifiable operator stands behind the free Claude relays — the upstream is unknown

Asked:

"Ok 3 or more are offering Claude for free where is the real Provider Provider Like api.justdowork.icu or kktoken.cc all free but where is the real Provider pls find him"

Four public-evidence findings cover three services — JustDoWork, KKtoken AI and AgentRouter — plus domain intelligence on JustDoWork's gateway. All three are third-party relays or aggregators; none discloses its upstream model-account supplier or legal operator. Anthropic is the official Claude provider, but no verified connection links these relays to it. Note the domain correction: the sources use api.justwoker.icu, not api.justdowork.icu.

Solid line: verified relationship stated in public sources. Dashed line: unverified — no public evidence identifies the upstream. Hover any box for the evidence behind it.

What the evidence says

The domain users type is a typo: the observed service URL is api.justwoker.icu, created 2026-08-14 and fronted by Cloudflare — infrastructure, not proof of ownership or model supply. gridinsoft.com

A public directory lists JustDoWork as an Anthropic/OpenAI-compatible relay with signup and check-in credits, but its models require login and no operator is named. github.com

KKtoken AI is described as a New API relay with promotional credits and token pricing; like JustDoWork, it discloses no upstream or legal operator. github.com

AgentRouter is independently documented as a Chinese API aggregator behind an Aliyun WAF — that identifies gateway infrastructure only, not who supplies the model accounts. github.com

Generous free balances prove nothing about legitimate Anthropic capacity: they could reflect subsidized credits, shared or resold accounts, alternative backends, or a short-lived promotion — public evidence cannot distinguish among them. Safety conclusion: do not send proprietary code, secrets, production API keys, or personal data through an unidentified relay.

Evidence table

Service	Classification	Verified finding	Upstream / operator	Confidence	Source

Method: 4 findings from public sources — a community directory of free AI sites, independent GitHub technical documentation, and a third-party domain-intelligence scanner — one row per service or infrastructure finding. "Verified" means stated in a public source, not confirmed by the operator. No owner is named because none is publicly verifiable; nothing was cut.
