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
Returns GDELT document search results including news article metadata, URLs, publication dates, themes, sentiment signals, and event-linked coverage relevant to the query — enabling AI-driven analysis of global media narratives around DeFi and crypto topics.
Example use cases
DeFi protocol media sentiment research
“Search GDELT for news documents mentioning Aave over the last 30 days — I want to understand global media sentiment around that protocol before making an investment decision.”
Geopolitical crypto market impact analysis
“Find GDELT documents about regulatory crackdowns on DeFi in Asia from the past two weeks — I need to understand how the news cycle might be affecting on-chain activity.”
Emerging narrative detection for a token
“Query GDELT for global news coverage of the term 'liquid staking' from the past month — I'm trying to spot whether this narrative is gaining mainstream media traction.”
