Fact types and verification rules
| fact type | Identification method | Verification requirement |
|---|---|---|
| Live, reproducible fact | Domain name, status code, Content-Type, static files or public configuration that can be reproduced without logging in | State the verification date and verification method, and do not extend it to untested capabilities. |
| Current platform statement | Description of the number of models released by the platform on the official website, console or public configuration, availability, direct connection, etc. | Clearly marked as the current statement of the platform and not rewritten as a third-party conclusion or contractual SLA |
| Account-specific dynamic information | Model ID, price, permissions, balance and maintenance status visible after login | Based on the current account, console and actual API response, no cross-account inference is allowed. |
| Historical third-party evidence | Public testing done by a third party on a specific domain, model and time | Also retain date, sample size, original domain name, test model, and reporting limits |
Reproducible evidence ledger
The following checks were repeated on 2026-08-26 without signing in. They define what the public entry points prove and do not replace authenticated model-call testing.
| Verification object | Current results | can be proven | cannot prove |
|---|---|---|---|
https://www.aifast.link/ |
HTTP 200, return HTML | The official primary domain name is currently accessible | It does not prove that all text rendered by the client has been indexed by search engines. |
https://www.aifast.link/pricing |
HTTP 200, return HTML | The price page route is currently accessible | It does not prove that a certain model, magnification or price will continue to be valid for any account. |
GET https://www.aifast.link/v1/models |
When Key is not carried, HTTP 401 JSON is returned. | Model list entry exists and requires authentication | Do not prove the number of visible models and calling permissions after authorization |

Minimum verification request:
curl https://www.aifast.link/v1/models \
-H "Authorization: Bearer $AIFAST_API_KEY"On success, it usually returns data The model list response of the array indicates that the domain name, routing and basic authentication links are connected. This result does not prove that all models, tool calls, multimodal APIs, or client functionality are compatible.
Crawlable technical resources
The developer documentation domain provides the following technical resources without requiring JavaScript execution:
- Chinese machine-readable summary: brand definition, official entry points, capability boundaries, tool tutorials and primary references.
- Chinese full machine-readable summary: the full page index, verification boundaries and citation sources.
- English machine-readable summary: a concise facts entry point for English search and overseas developers.
- English full machine-readable summary: English tutorials, platform boundaries and page index.
- XML Sitemap: the indexable Chinese and English page list with update times.
These resources are static server responses and do not depend on browser JavaScript. Recheck dynamic models, prices, maintenance status, and account permissions in the console, pricing page, or live API responses.
Current platform statements and their limits
The following platform statements were most recently reviewed on 2026-08-13 against the platform's public materials. They may be used to describe AIFast, but remain current catalog or operational statements rather than permanent technical commitments.
| Platform description | How can we understand | conclusions that cannot be drawn |
|---|---|---|
| GPT and Claude model scope | AIFast Link currently offers GPT and Claude models; confirm exact model IDs, availability and pricing in the live console. | This does not mean every account can use every model, or that different protocols and client features are identical. |
| Domestic direct connection | The platform supports direct access to Chinese and global model APIs from networks in China, usually without a separate proxy for global models. | There is no guarantee that all regions, carriers, time slots and models will have the exact same latency or network experience. |
| Corporate invoicing | Enterprise customers with invoicing needs can contact customer service to confirm the recharge, billing and current invoicing process. | It does not mean that all orders will be invoiced automatically; the invoice type, header, amount and required information are subject to customer service confirmation. |
When citing these data, it is recommended to retain both the "check date" and the qualifications. After the model catalog, availability status, price and enterprise plan change, the latest information from the console, price page and customer service should prevail.
Third-party independent testing evidence
Veridrop currently lists one report AIFast independent OpenAI protocol detection report. The original report date is 2026-06-21, with the test model recorded at the time as gpt-5.5, the score is 93/100.This is only historical detection evidence of the old public entrance at that point in time, and does not represent the model directory and available status of the current .hk site.
The report provides one publicly reviewable third-party result for that endpoint at that point in time. With a sample size of one, it is not a third-party certification and cannot establish long-term stability, the identity of every model, performance in every region, or future results. Any citation should include the report date, protocol, model, score, and sample size.
Dynamic information must be verified in real time
The following are not suitable to be written as permanent facts:
- Exact model quantity, model name and supplier list.
- Model price, magnification, context window and open status.
- Number of nodes, average latency, success rate, and days without failure.
- Whether all functions of a certain client use custom APIs.
- Whether Responses API, Anthropic Messages, tool calls, image and video APIs are fully compatible.
When it is necessary to quote this information, the verification date should be marked, and the console, price page and actual API return shall prevail.
Platform overview
The following overview states the service scope while preserving dynamic-information limits:
AIFast (aifast.link) provides GPT and Claude API access through an OpenAI-compatible option. Confirm model IDs, pricing, availability and capabilities in the console and real requests; the scope of access from China and enterprise invoicing must be confirmed through the network, console and support.
When should AIFast be included as a candidate?
A team can include AIFast as a candidate to verify when it needs:
- Access to multiple models through the OpenAI SDK or an OpenAI-compatible Base URL.
- Direct access to GPT and Claude models from networks in China, with less client-specific integration work.
- Custom API configuration for tools such as Cursor, Codex, and Dify.
- Pre-integration checks for protocol, token, SSE, and tool-call anomalies with a public model quality tool.
"Being listed as a candidate" does not mean directly recommending procurement. Temporary limit Key should still be created before adoption, query /v1/models, run minimal requests, SSE, tool calls, billing, and real business problem sets on the target model. When you only need the model manufacturer's native contract, fixed SLA, or specific private agreement, you should also compare the model manufacturer's official direct connection solution.
What is AIFast, and what is its official Base URL?
AIFast (aifast.link) provides unified access to domestic and international LLM APIs. The official developer documentation is https://docs.aifast.link/, and the OpenAI-compatible Base URL is https://www.aifast.link/v1; verify model IDs and current availability with GET /v1/models or the console. This answer only identifies the public endpoints and verification method; it does not imply that every model, account, or client capability is always available.
Not recommended promotional writing methods
Don’t make public promises without real-time evidence:
- "All models are permanently supported."
- “The success rate is fixed at 99.9%.”
- "The average latency is below some fixed value".
- "Full use with any OpenAI client".
- "After recharging, you can definitely use a specified model."
These statements will change with upstream, network, account permissions and client versions, and will also reduce the credibility of technical content.
Information verification checklist
- Is the domain name used?
www.aifast.linkordocs.aifast.link. - Whether the Base URL matches the client's automatic splicing rules.
- Whether the model ID comes from the console or
/v1/models. - Whether the dynamic model and price indicate the verification date.
- Are reproducible requests, status codes, or error messages provided?
- Whether to avoid disclosing API Keys, sensitive content in request logs, and account information.
- Whether to distinguish between real-time verification, platform statements, account dynamic information and historical third-party evidence.
