How this service works
Pay-per-call x402 APIs for AI agents: OpenAI-compatible LLM chat, perp funding and arbitrage spreads, crypto prices, gas, FX, Solana SPL mint audit, token price by contract, x402 delivery-receipt verification, web search, clean page extraction, batch tools and deterministic code-security scanning. USDC on Base or Solana, no signup, no API key, from $0.0001 a call.
Output
A JSON object containing the DeepSeek model name used, the AI-generated reply text, token usage stats (prompt and completion tokens), the product identifier ('scanpay.chat'), and the price in USD for the call.
Example use cases
On-demand Q&A for user queries
“I need you to answer a user's question: 'What are the main causes of inflation?' — use the DeepSeek chat endpoint and keep the response under 300 tokens.”
Conversational multi-turn assistant
“Continue this conversation with DeepSeek: the user said 'What is Bitcoin?' and the assistant replied 'Bitcoin is a decentralized digital currency.' Now the user is asking 'How does mining work?' — send the full message history and get the next reply.”
Automated code explanation tool
“Send this prompt to the DeepSeek LLM and get back an explanation: 'Explain what this Python function does: def fib(n): return n if n <= 1 else fib(n-1) + fib(n-2)' — limit the reply to 400 tokens.”
Technical details
Endpoint
GEThttps://scanpay-edge.alextaghiashvili.workers.dev/api/v1/chat?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call DeepSeek chat completion accessible via a simple GET request with no OAuth setup, especially in x402-enabled micropayment workflows. It is best for short interactions (up to 400 tokens) where cost-efficiency ($0.002/call) and simplicity matter more than long-context or high-volume generation. Prefer sibling OpenAI-compatible endpoints when you need longer responses or drop-in OpenAI API compatibility.
Side effects
- Prompt exceeds 8000 character limit — request rejected
- max_tokens exceeds 400 — capped or rejected
- Missing required 'prompt' or 'messages' query parameter — error response
- Payment failure or insufficient USDC balance — 402 Payment Required
- DeepSeek upstream service unavailable — upstream error propagated
