How this service works
AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.
Output
A plain-text summary of the provided content, generated by the selected Groq-hosted LLM. Length is bounded by the maxTokens parameter (default 512). No structured JSON envelope is guaranteed — the response body is the summarized text.
Example use cases
DeFi protocol governance digest
“Condense this Aave governance proposal into a short summary using the llama-3.3-70b-versatile model — keep it under 300 tokens so I can share it in our Discord: [paste proposal text].”
Crypto news headline roundup
“I have these 10 DeFi news headlines from today — can you join them into a single paragraph summary using llama-3.1-8b-instant, with a focus on activity in the Asia-Pacific region?”
Research report distillation
“Summarize this long on-chain analytics report for me using the mixtral-8x7b-32768 model, max 512 tokens, so I can get the key takeaways quickly: [paste report text].”
Technical details
Endpoint
POSThttps://chat.sperax.io/api/x402/groq-summarize?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, fast text summarization paid micropayment-style with no API key setup, especially in DeFi/crypto contexts or when building agents that use x402 pay-per-call infrastructure on Base. Prefer over OpenAI or Anthropic direct calls when you want USDC billing and Groq's low-latency LLaMA models.
Side effects
- Payment not received or insufficient USDC balance causes 402 Payment Required response
- Text input missing and headlines array is empty causes validation error
- Selected model unavailable on Groq infrastructure causes 503 or timeout
- maxTokens set too low results in truncated or incomplete summary
- Network timeout if Groq inference takes longer than expected
