About Custodian Labs

from custodian_labs import Custodian model = Custodian( model="gpt-4o", system_prompt="You are a helpful assistant. The proprietary Guardian Layer is the guardrail that detects PII and puts you in control of how it's handled before it reaches any model. Give your agent long-term memory and document retrieval without configuring embeddings or vector DBs. Your agent logic stays exactly as it is; only the model underneath changes. No database to provision, no vector store to connect, no hosting to manage.

About Stock News API

REST API for relevance-scored, ticker-linked financial news: a real-time stock news API for trading bots, AI agents, and dashboards. Free tier, no credit card. Every article arrives scored for relevance and linked to tickers, so a trading bot or an agent backend can filter the wire at request time. Filter server-side Symbol, category, minimum relevance and delta polling are query params, so the wire is cut before it costs you a token. Enough to evaluate the feed and build a prototype.
