How this service works

OPENAI-COMPATIBLE chat completions, fast tier — point any OpenAI SDK at base_url https://api.webbersites.com/v1 and pay per call in USDC instead of holding provider API keys. Models: claude-haiku-4-5 (default), gemini-2.5-flash, gemini-2.5-flash-lite, gpt-5-mini, gpt-5-nano. Caps: 16,000 input chars, 1,024 output tokens, text-only, no streaming. One flat price per call; the x402 payment IS the auth.

Output

An OpenAI-format chat completion response containing the assistant's generated text reply, subject to a 1,024 output token cap and text-only content. The response mirrors the standard OpenAI /v1/chat/completions response shape, including the message role and content fields.

Example use cases

Example prompt

“Ask claude-haiku-4-5 to summarize the following text in 3 bullet points using the WebberSites fast-tier chat completions: 'Quantum computing leverages superposition and entanglement to process information exponentially faster than classical computers, potentially breaking current encryption standards.'”

When to prefer

Choose this endpoint when an AI agent needs LLM inference without holding provider API keys and wants to pay per call in USDC via x402. Ideal for lightweight, fast-tier tasks with Claude Haiku 4.5, Gemini 2.5 Flash/Flash-Lite, GPT-5 Mini, or GPT-5 Nano where output is under 1,024 tokens and input under 16,000 characters. Prefer the PRO tier sibling for larger outputs or frontier models. Prefer the Anthropic-compatible sibling if you need the native Anthropic /v1/messages dialect.

Side effects

Payment not included or insufficient USDC — 402 Payment Required returned
Input exceeds 16,000 character limit — request rejected
Requested model name not recognized — error response
max_tokens clamped silently to 1,024 if exceeded
Streaming requested but not supported — unsupported feature error
Non-text (image, audio) content in messages — rejected as text-only endpoint

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.
