Cryptographically Signed Data
for AI Agents
MCP servers delivering verifiable Brazilian financial, commodity, and company data. Every payload signed at the source — your agents get facts, not guesses.
Data your agents can trust
HTTPS secures the channel. We anchor the payload. Every CDS event is a self-contained proof of what was published, by whom, and when.
Cryptographically Signed
Every data point carries an RSA-PSS signature proving exactly who published it and when. No trust assumptions beyond the cryptographic proof.
Real-Time Updates
Scheduled ingestors fetch fresh data from Banco Central, B3, CONAB, and Receita Federal. Daily rates, weekly commodities, live quotes.
LLM-Ready Summaries
Each event includes a structured summary so data and meaning travel together. AI agents understand context without extra prompting.
Verified Sources
All data sources are registered and fingerprinted in the CDS source registry. No unverified scraping — curated, structured, auditable.
Three domains, one standard
