langchain-fodda
Official LangChain custom tool integration for the Fodda Context Layer — verified knowledge graphs, live supplemental market intelligence, and working Human Agents for autonomous AI reasoning models.
Installation
pip install langchain-fodda
Quickstart
from langchain_fodda import FoddaContextRetriever
# Initialize tool (API key optional for unauthenticated discovery / x402 on-chain settlement)
fodda_tool = FoddaContextRetriever(api_key="sk_live_...")
# Query a knowledge graph
result = fodda_tool.run("psfk-retail")
print(result)
Features
- Autonomous 402 Paywall Handling: Gracefully catches HTTP 402 challenges. If no credentials or wallet are configured, it automatically falls back to Fodda's verified markdown schema summaries (
free_readme) so the LLM reasoning loop never crashes. - Base USDC Micro-Settlement: Supports on-chain 5¢ Base USDC payments via
X-402-Payment. - Stripe Shared Payment Tokens (SPT): Supports zero-friction bearer token settlement.
