How this service works
Call OpenAI's gpt-5.5 via a single pay-per-call x402 endpoint — no OpenAI account or API key needed, pay $0.65 per request in USDC. Standard OpenAI chat.completions request/response shape, capped input and output. Search terms: OpenAI, gpt-5.5, chat completion, LLM, no API key.
Output
Returns a standard OpenAI chat.completion JSON object containing: the assistant's reply in choices[0].message.content, finish_reason, model name, a unique completion ID, Unix timestamp, and a usage object with prompt_tokens, completion_tokens, and total_tokens. Output is capped at 8192 tokens.
Example use cases
One-off LLM call without OpenAI account
“I need to ask GPT-5.5 to draft a short apology email to a client — I don't have an OpenAI account, just run it pay-per-call in USDC.”
Agent pipeline with per-call LLM billing
“My automation workflow needs to classify incoming support tickets using GPT-5.5 — route each one through a pay-per-request endpoint so I'm billed in USDC only when it runs.”
Rapid GPT-5.5 prototype without subscription
“I'm prototyping a chatbot and want to try GPT-5.5 right now — just send it a system prompt saying 'You are a helpful cooking assistant' and a user message asking for a quick pasta recipe, billed per call.”
Technical details
Endpoint
POSThttps://netintel.dev/openai/gpt-5-5When to prefer
Choose this endpoint when you need GPT-5.5 specifically (not an older model) and want to avoid managing OpenAI API keys or subscriptions — ideal for agents, automation pipelines, or prototypes that need pay-per-call billing in USDC via x402. Prefer this over the gpt-4.1 or gpt-4o siblings when you want the most capable model in the netintel.dev gateway lineup. Skip it if you need streaming responses, function/tool calling, image inputs, or cost-sensitive high-volume usage where a direct OpenAI subscription would be cheaper.
Side effects
- Payment not provided or insufficient USDC — returns 402 Payment Required
- Input messages array missing or malformed — returns 400 Bad Request
- Total input characters exceed ~96,000 char cap — request rejected
- max_completion_tokens set above 8192 — capped or rejected
- OpenAI upstream timeout or error — returns 502 or 503
- Invalid role values in messages (not system/user/assistant) — schema validation error
