# LLM Subscription-Resale Markets
|
||
|
||
## Summary
|
||
|
||
A class of inference gateways sells frontier-model access far below the vendor's list price (80% off on a Claude subscription family, up to 99.9% off on others). They do not buy tokens from the model vendors and they do not have a wholesale deal. They operate a **two-sided market for other people's subscription entitlements and free-tier credits**, priced by a cheapest-wins auction, and they route the traffic through pooled credentials fronted by rotating egress proxies.
|
||
|
||
Primary case studied: **InferHub** (`inferhub.dev`), a USDC-on-Solana marketplace with 74,310 listed active providers, 155 routable model IDs, and 5.68 M requests / 406.5 bn input tokens measured over one 24-hour window.
|
||
|
||
## Research Question
|
||
|
||
How can a third-party gateway serve frontier Claude/GPT/Gemini models at 80% or more below the vendor's official per-token price — and what does that architecture imply for the people buying and selling through it?
|
||
|
||
## Scope
|
||
|
||
**Included:** the supply side (where the capacity comes from), the routing/auction mechanism, the credential-ingestion pipeline, the measured scale, the reliability profile, and the terms-of-service/legal exposure for both sides of the market.
|
||
|
||
**Excluded:** attempting to authenticate, testing any credential, exploiting any endpoint, and black-box model-fingerprinting (needs a paid account — left as a next step).
|
||
|
||
**Sufficient answer:** the supply mechanism is identified and its chain traced to a concrete, purchasable artefact, with the decisive claims backed by first-party or vendor-primary sources.
|
||
|
||
**Method:** passive, unauthenticated reconnaissance only. Public pages, public JS/CSS, public API schemas and unauthenticated error responses, public marketplaces, DNS, npm, public code hosts. No account created, no key sent, no auth bypassed, ~1 s pacing.
|
||
|
||
## Key Findings
|
||
|
||
- **The model is subscription resale, admitted in the operator's own terms.** InferHub's ToS §2: *"a reverse proxy and marketplace that resells access to upstream LLM subscription entitlements, including subscriptions accessed via OAuth (such as Claude and Codex), API-key-based plans (such as Command Code), and coding plans offered by third parties (such as z.ai GLM Coding Plan and OpenCode Go)."*
|
||
- **All 14 upstream families are consumer coding-agent subscriptions, not metered APIs.** `GET /api/market` (public) returns a `family` per model: CodeBuddy, CodeBuddy CN, Command Code, OpenCode Go, ClinePass, Claude Code, OpenAI Codex, Qwencloud/Alibaba (+CN), Antigravity (Google), MiniMax (+CN), Z.AI GLM Coding Plan, Xiaomi MiMo.
|
||
- **The discount is auction clearing price, not a purchase discount.** `GET /api/pricing/config` returns `{"maxAskPctOfOfficial":0.5,"platformFeePct":0.2,"publisherSharePct":80}`: a publisher ask is capped at 50% of official, and competition between publishers pushes it far below the cap, because the seller's marginal cost is approximately zero once the flat subscription is paid.
|
||
- **There are two distinct supply tiers under one roof**, and they are different businesses:
|
||
- **Paid subscription arbitrage** (`cc/` Claude Code, `cx/` Codex, `zai/`, `ocg/` OpenCode Go, `cmc/` Command Code, `cp/` ClinePass) — a real sunk monthly cost per account. This is the tier that produces the owner's headline 80% figure: `cc/claude-opus-5-5` asks $0.796/Mtok against official $4.
|
||
- **Free-tier / promo-credit farming** (`cb/` CodeBuddy, `cbcn/`, `ag/` Google Antigravity, `ali*/`) — acquisition cost is one account signup, and on the secondary market ~$0.11–0.14 per account. This is the tier that produces the 99% rows.
|
||
- **Free-tier farming is productised as a platform feature.** InferHub's public OpenAPI documents `POST /publisher/providers/antigravity/bulk` — *"Bulk-add Antigravity (Google) accounts from refresh tokens … each account is refreshed for a live access token and **onboarded onto a Cloud Code Assist project**"* — plus `*/codex/bulk`, `*/codebuddy/refresh-tokens`, `*/recheck-bulk`, `*/invalid`, `*/usage-windows` and `*/auto-reset-credit` ("Codex only; auto-spends real money"). A single publisher is documented as able to hold "six figures of credentials".
|
||
- **A concrete, purchasable artefact sits at the bottom of the chain.** Indonesian marketplace `mastumbas.id` sells CodeBuddy accounts — access token + refresh token, 450 starting credits, +30 credits/day auto-claim — at **Rp 2,300 (~$0.14)** retail, Rp 1,800 at ≥100 units, 3,303 sold. Cline accounts, CodeBuddy-CN refresh tokens and 1-day Webshare proxy packs sell on the same shelf.
|
||
- **Decisive link (slug correspondence, VERIFIED):** 19 of InferHub's 23 `cb/` slugs match that listing's advertised model codes exactly, including `claude-opus-4.6` and `claude-opus-4.7-1m` — which InferHub asks **$0.04/Mtok** for against an official $5, i.e. 99.2% off. That capacity is reachable through a $0.14 account, not through any arrangement with Anthropic.
|
||
- **The vendor's free tier is the engine: ~1,000 credits/month at zero cost.** CodeBuddy Free = 100 credits/month + 30 credits/day (limited-time daily-activity bonus) + 250 welcome credits; all models available while the promotion runs. Tencent bans exactly this in its own subscription policy (*"scripts, plug-ins, emulators, API calls, bulk registration, or other means to farm activity or rewards"*; *"maliciously creating or controlling multiple accounts"*; *"bulk registration, account sharing, account trading"*).
|
||
- **The volume is in the cheap commodity tier, not the flagships.** CodeBuddy is **50% of all requests and 66% of all input tokens**; the real Claude Code family is **0.57% of requests**. The 80%-off Claude row is the shop window.
|
||
- **The landing terms forbid the business model outright.** Claude Code's own legal & compliance page: *"Customers may not pay for, resell, or intermediate Claude usage on their end users' behalf"* and developers *"may not collect, store, or intermediate Claude.ai credentials or session tokens"*. InferHub does all three for the Claude Code upstream.
|
||
- **Consumers pay for the cheapness in failure rate and latency, and in data exposure.** API availability 24 h **96.4%**, with error causes no_capacity 62.7% / upstream_failed 37.2%; TTFT 5–19 s; `claude-fable-5` auto-route at **35%** 24 h availability. InferHub's privacy policy retains the consumer's **system prompt and tool definitions for 7 days** on security-policy rejections, retains screened message text for 14 days, and documents that some upstreams **prepend their own agent prompt** to the consumer's request.
|
||
- **The mechanic is a category, not an original.** Surplus Intelligence runs the same open market on Base rails ("your surplus capacity, sold to the highest bidder"); `inferencehub.tech` in the same niche labels the sector "**gray-market supply**" in its own comparison copy; FreeLLMAPI aggregates 34 free providers; OmniRoute publishes a ToS table of 15 providers whose terms prohibit proxy access.

## Discussion
|
||
|
||
Raised by **brutaljokerz** in `#research` on 2026-10-05 while looking at `inferhub.dev/pricing` ("how does it serve models very cheap especially opus 5.5, frontier at 80% discount?"), with an operator-posted screenshot of a proxy-vendor dashboard (1,000 proxies, 4.44 TB, 2.87 M requests since 24 Sep 2026) posted by Discord handle **ExZork** in reply to a question about the platform "handling tens of thousands of accounts".
|
||
|
||
Follow-up in the same thread connected it to the September free-token-gateway study and to the CodeBuddy-account resale market; the operator's npm package `@inferhub/helper` carries maintainer `exzork`, which matches the Discord handle. The platform describes itself as "operated by its developer as an individual"; the jurisdiction is not disclosed.

|
||
|
||
## Next Steps
|
||
|
||
- [ ] Fold in the three deep lanes still running at time of writing (credential/quota mechanism, GMV economics with the two-tier split, and the remaining 13 vendors' upstream clauses)
|
||
- [ ] Owner to add additional material in-thread
|
||
- [ ] Decide `draft: false` if this goes to the public Quartz site
|
||
|
||
## Conclusion
|
||
|
||
Open — `status: active`. The supply mechanism is settled; the economics quantification and the enforcement record are not.
