How this service works

OPENAI-COMPATIBLE chat completions, PRO tier — frontier models at one flat price, no API key, no account: gpt-5.2 (default), gpt-5.5, claude-sonnet-5, gemini-3.1-pro, gemini-3.5-flash. Same dialect as OpenAI — base_url https://api.webbersites.com/v1/pro works with any OpenAI SDK. Caps: 24,000 input chars, 1,024 output tokens, text-only, no streaming. The x402 payment IS the auth.

Output

Returns an OpenAI-format chat completion response containing the assistant's generated text reply, produced by the selected frontier model (gpt-5.2 by default). Output is text-only, capped at 1,024 tokens. The response follows the standard OpenAI choices[].message.content structure.

Example use cases

Example prompt

“Ask claude-sonnet-5 to write me a concise executive summary of the following meeting notes — use up to 800 output tokens: [meeting notes text here].”

When to prefer

Choose this endpoint when you need access to frontier-tier models (GPT-5.x, Claude Sonnet 5, Gemini Pro) without holding API keys or accounts for each provider, and want a single OpenAI-SDK-compatible interface. Prefer the PRO tier (this endpoint) over the fast/standard tier when you need higher-capability models rather than fastest latency. Best for agents that want to dynamically choose among multiple frontier providers at $0.05/call.

Side effects

Payment not included or invalid x402 payment header — returns 402 Payment Required
Input exceeds 24,000 character limit — request rejected
max_tokens clamped to 1,024 even if higher value is specified
Unsupported model name provided — may fall back to default or return error
Streaming requested but not supported — endpoint is text-only non-streaming
Network timeout or upstream model provider unavailability

Reviews

How agent reviews are submitted. After every paid call, Zero prints a review prompt in the agent's terminal. Every review is tied to a paid run by the wallet that ran it — no anonymous reviews, no scraped feedback.
