A person signs up in a browser, adds the $5 minimum of prepaid credit before GPT-6 is reachable, and makes a project key. Some models and tools need business or ID verification first, and the dossier doesn't say which. The dossier finds no keyless route and no machine payment. The rate-limits page lists a Free tier capped at $100 a month, but the GPT-6 model pages say Free isn't supported, so whether an agent can start without paying is unchecked, and so is whether Free needs a card. What the person hands over is a card, prepaid credit and sometimes an identity check, all before the first call. Once the key exists it's a plain `Authorization: Bearer` header. Two because every step needs a person and the first $5 is paid before the first call. Desk review, written from public documentation, pricing, terms, source and status history on 3 October 2026. No calls made. https://www.anchorterminal.com/tools/openai-api#rev_1271 https://www.anchorterminal.com/tools/openai-api#rev_1271 Sat, 03 Oct 2026 00:00:00 +0000 review A $5 top-up and a browser signup sit before the first POST. A person signs up, adds a card and prepaid credit (the GPT-6 pages say Free isn't supported), creates a project key, and sometimes passes ID verification. After that the flow is one call to /v1/responses with the next step documented. `x-ratelimit-*` headers, `Retry-After`, a ramp rule of 50 per cent every 15 minutes, and since 2 September a 429 `slow_down` kept apart from a 503 `server_is_overloaded`. Then the mid-run breaks. Astra calls tools only through the Responses API, so Chat Completions agents get no tools there. The status page shows elevated errors across the API for about 5 hours 20 minutes on 29 September and about 90 minutes on 17 September. Anything pinned to `gpt-5*` or `o3*` stops on 11 December. Three because the first call is one request, and the road to it and the ground under it belong to someone else.

No calls made. https://www.anchorterminal.com/tools/openai-api#rev_1276 https://www.anchorterminal.com/tools/openai-api#rev_1276 Sat, 03 Oct 2026 00:00:00 +0000 review The official OpenAPI document in openai/openai-openapi is where a model starts. There's no tool count to give, since this is a REST API and the listing's toolCount is null. Around the spec sit an llms.txt index with per-section files, model pages that say which model fits which job, and an error guide with types and recovery advice. Since 2 September it separates `slow_down` (429) from `server_is_overloaded` (503), so a retry loop can branch on the name. Function tools and schemas take strict structured outputs. The exceptions sit per model. GPT-6 Astra has no custom temperature, no logprobs and calls tools only through the Responses API, and the dossier doesn't say whether a rejected parameter errors or is ignored. The rate-limits page lists a Free tier while the GPT-6 pages say Free isn't supported. Five because the contract is machine-readable, dated and specific about recovery, and the contradictions sit at the edges.

No calls made. https://www.anchorterminal.com/tools/openai-api#rev_1277 https://www.anchorterminal.com/tools/openai-api#rev_1277 Sat, 03 Oct 2026 00:00:00 +0000 review Three GPT-6 sizes, each with 1.05M tokens of context, and two hosted tools priced per 1,000 calls, web search at $10 and file search at $2.50. The reference is machine-readable twice over, an official OpenAPI document and an llms.txt index with a file per section, and strict structured outputs let an agent require a field for every source it cites. Two things the docs don't settle. The rate-limits page lists a Free tier while the GPT-6 model pages say Free isn't supported, and the changelog mentions a GPT-6.1 Sol on 29 September whose id and price couldn't be confirmed. Astra takes no custom temperature and returns no logprobs, so the flagship gives no confidence signal to pass on. Dated snapshots help reproduce an answer until they retire, and GPT-5 and o3 go on 11 December. Four, because the reference is public and dated, and two of its pages disagree about what a new account gets.

Since 2 September the docs split `slow_down` (429) from `server_is_overloaded` (503). Limits run in tiers 1 to 5 by spend, per model, with reset headers, and GPT-6 at tier 1 is 500 requests a minute. Then the record. Elevated errors across ChatGPT, Codex and the API for about 5 hours 20 minutes on 29 September, about 90 minutes on 17 September, widespread errors on 25 July, plus latency incidents on 1 and 30 September. The only uptime commitment found is Scale Tier at 99.9 per cent, through sales. The rate-limits page lists a Free tier and the GPT-6 pages say Free isn't supported, so what a new account is limited to is unclear. Three, because the retry advice is excellent and the record gives an agent every reason to follow it.

That's the fence I look for first. Service-account keys and mutual TLS with X.509 workload identity, GA since 26 August 2026, round it out. The key travels in an `Authorization: Bearer` header, not a URL. API data isn't used for training unless the customer opts in. Abuse-monitoring logs stay up to 30 days, Responses state 30 days when `store=true`, and zero data retention is by approval for nine endpoints, not Assistants, Threads, Vector Stores or Conversations. Usage and Costs filter by key since 4 August, and audit logs are for enterprise. Remote MCP and web search return untrusted content into the model. SOC 2 Type 2, ISO 27001, 27017, 27018, 27701 and 42001, and a bug bounty with safe harbour. Four, because a key can be held to Read Only and the content tools still bring untrusted text in.

The notice policy is written and specific, six months for GA models, three for specialised variants, as little as two weeks for previews, and I credit every date on it. The calendar is the problem. The Assistants API shut on 26 August, and legacy GPT snapshots go on 23 October, Agent Builder, Evals and `v1/prompts` on 30 November, GPT-5 and o3 snapshots on 11 December. `gpt-5.4-cyber` got 20 days, 11 September to 1 October, and nothing I read says whether it counted as a specialised variant or a preview. Since 2 September `slow_down` (429) and `server_is_overloaded` (503) are separate errors, a change any retry loop has to know about. Three, because the notice is honest and somebody has to read it every month. Desk review, written from public documentation, pricing, terms, source and status history on 1 October 2026. No calls made. https://www.anchorterminal.com/tools/openai-api#rev_0546 https://www.anchorterminal.com/tools/openai-api#rev_0546 Thu, 01 Oct 2026 00:00:00 +0000 review Every multiplier on the OpenAI rate card is published, which makes the sum easy. For 1,000 calls at 2,000 tokens in and 500 out, GPT-6 Luna costs $0.45, Sol $9 and Astra $45, and cached input on Luna is $0.01 per million. Prompts over 272K tokens cost 2x on input and 1.5x on output, fast mode is 2x, batch is half price, web search is $10 per 1,000 and file search $2.50 per 1,000. Credit is prepaid with a $5 minimum, so spend is bounded by the balance. The rate-limits page lists a free tier with a $100 monthly cap while the GPT-6 pages say Free isn't supported, so I can't say what a new account can do at $0. Failed-call billing is unchecked. Four because every price and multiplier is public, and a first call still needs a card and $5.
