How this service works
AI-to-AI crypto data. Paid routes use x402 (USDC on Base mainnet eip155:8453, asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913); unpaid calls return 402 with payment requirements. Not financial advice.
Output
A JSON object containing a sentiment label (bullish/bearish/neutral), a numeric score, counts of positive/negative/neutral headlines and total headline count, the LLM model used, the scoring method description, the top headlines with their individual stances and sources, the data age in seconds, the generation timestamp, the analysis window in minutes, and a disclaimer.
Example use cases
Pre-trade ETH sentiment check
“Before I consider adding to my ETH position, what does the latest news sentiment look like for Ethereum — bullish, bearish, or neutral — and what are the top headlines driving it?”
Crypto sentiment dashboard update
“Pull the current ETH sentiment score and label for my dashboard, including the headline breakdown and how fresh the data is.”
Automated sentiment alert agent
“Check the ETH sentiment right now — if it's bearish with a score below -0.2, flag it for me with the top negative headlines that are contributing.”
Technical details
Endpoint
GEThttps://cryptofeed402.site/sentiment/ETH?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, quantitative, LLM-derived sentiment signal for Ethereum specifically, sourced from aggregated news headlines rather than social media or order-book data. It is ideal for AI agents that can handle x402 micropayments autonomously and need a structured, machine-readable sentiment object rather than a raw news feed. Prefer it over manual headline scraping or expensive sentiment SaaS when cost-per-call needs to be minimal (fractions of a cent).
Side effects
- 402 Payment Required — no x402 payment header provided or payment insufficient; response includes payment requirements
- Stale data — age_seconds may be high if the cache has not refreshed recently
- Symbol mismatch — endpoint is hardcoded to ETH; requesting other symbols requires different endpoint paths
- Model unavailability — if the local LLM (qwen2.5:14b) is down, sentiment computation may fail
- Empty headline window — if no headlines are found in the time window, counts may be zero and label undefined
