APImart Alternative: OneAster
APImart resells a broad menu of model APIs. OneAster starts from the operating guarantees instead: four native wire protocols, acceptance-based publication gates so a listed model is a verified model, per-task reserve/settle billing with an exportable ledger, and a product that speaks 12 languages natively.
中文摘要
中文摘要：APImart 以市场模式转售各类模型 API；OneAster 从运营保障出发：四种原生协议（OpenAI Chat/Responses、Anthropic Messages、Gemini）、/v1/embeddings 向量端点、验收制质量门禁（参数/价格/用量证据核验后才能上线）。
资金采用任务级“报价预留—实耗结算—余款释放”的透明台账，支持 CSV 导出对账；界面原生支持 12 种语言（含 RTL）。我们是新平台（v0.7.x），型号目录小于市场型平台、陆续上线并如实标注。迁移三步：改 base URL（OpenAI 兼容客户端用 https://api.oneaster.ai/v1，Anthropic 客户端用 https://api.oneaster.ai）、换密钥、跑通一次请求。
How we compare, honestly
APImart is API marketplace reselling third-party model endpoints. The table below is what we can verify from our side; vendor features change, so confirm anything decision-critical on their site. Last reviewed 2026-10.
| APImart | OneAster | |
|---|---|---|
| Protocols 协议接入 | Marketplace-style REST per product | 4 native: OpenAI Chat & Responses, Anthropic Messages, Google Gemini, plus async /v1/tasks |
| Modalities 模型类别 | Depends on the resold products | Text, image, video, audio and embeddings in one catalog |
| Vector endpoint 向量端点 | Depends on the resold products | OpenAI-style /v1/embeddings (string inputs, dimensions, encoding_format) |
| Quality gate 质量门禁 | Per-product; you verify outputs yourself | Acceptance-based: a model publishes only after its parameters, prices and usage evidence pass verification |
| Cost transparency 资金透明 | Per-product pricing and quotas | Per-task reserve/settle ledger; quote before the run, refund of the unused reserve, CSV export |
| Interface languages 界面语言 | English UI | 12 languages, including RTL Arabic |
| Maturity (honest) 成熟度（如实） | Broad resold catalogue | New platform (v0.7.x); models roll out progressively, preview states are labelled |

Migrating in three steps · 迁移三步
Point your client at OneAster
把 base URL 指向 OneAster
OpenAI-compatible clients point at https://api.oneaster.ai/v1 (OpenAI SDK: baseURL). Anthropic SDK clients use https://api.oneaster.ai — the SDK appends /v1/messages itself. Codex/Claude Code: set the provider wire API as documented.
Swap in a OneAster key
替换为 OneAster 密钥
Create an account, generate a key (oa-…) in the console and send it as Authorization: Bearer. Keys carry per-key spend limits.
Run one request end to end
跑通一次请求
List models with GET /v1/models, run one chat or task, then check the quote, settlement and ledger entry in the console. That entry is your reconciliation baseline.
FAQ
Do I have to rewrite my application to migrate?
Usually no. OpenAI-compatible clients switch their base URL to https://api.oneaster.ai/v1; Anthropic-style and Gemini-style clients use https://api.oneaster.ai and keep their own path prefixes. Media work uses the async /v1/tasks API.
How is billing different?
One prepaid balance, settled per task: quote reserved, confirmed usage charged, remainder released, every movement in a CSV-exportable ledger. New accounts receive a welcome credit; the amount is set by the platform.
Which models can I run today?
The public catalog is the contract: each model shows availability, verified parameters, limits and price. It is smaller than a marketplace catalogue and grows continuously, with preview states labelled honestly.
Is OneAster production-ready?
v0.7.x — a young platform. Already shipped: acceptance gates, idempotency keys, settlement reconciliation, public status telemetry and full i18n/RTL. Run your own evaluation before migrating anything critical.
