langchain-primordia 0.1.1

Primordia economic metering for LangChain - track AI costs with machine-readable receipts

langchain-primordia

Economic settlement infrastructure for LangChain agents.

What is this?

Not just cost tracking. Clearing-grade settlement for AI agents.

MSR (local receipts)  →  IAN (kernel-signed netting)  →  MBS/ALR (audit-grade)
     FREE                      5 bps                        $25K+

Installation

pip install langchain-primordia

Quick Start (Shadow Mode - FREE)

from langchain_openai import ChatOpenAI
from langchain_primordia import PrimordiaCallbackHandler

handler = PrimordiaCallbackHandler(agent_id="agent-alpha")
llm = ChatOpenAI(callbacks=[handler])

response = llm.invoke("Hello")

# Local receipts accumulated
print(f"Receipts: {len(handler.get_receipts())}")
print(f"Total: ${handler.get_total_usd():.4f}")

Settlement (PAID - 5 bps)

When you need proof of settlement between agents:

handler = PrimordiaCallbackHandler(
    agent_id="agent-alpha",
    submit=True
)

# ... run your agent ...

# Net receipts into kernel-signed IAN
result = handler.net_receipts()

if "signed_ian" in result:
    # This is clearing-grade proof
    # Agent B can verify this signature
    print("IAN signed by Primordia kernel")
else:
    # 402 - need to purchase credit
    print(result["purchase_url"])

Audit-Grade Reports (Enterprise)

# Requires pack_team ($25K) minimum
mbs = handler.get_balance_sheet()

if "error" in mbs:
    # 402 - PACK_TEAM REQUIRED
    print("Purchase pack_team for audit-grade MBS")
else:
    # Kernel-signed Machine Balance Sheet
    print(mbs)

The Rail

Stage	What	Cost
MSR	Local receipt per LLM call	FREE
Index	Submit receipts to kernel	FREE
IAN	Kernel-signed netting	5 bps
MBS	Machine Balance Sheet	$100 (pack_team min)
ALR	Agent Liability Report	$100 (pack_team min)
Default	Resolution	$25,000

Why Kernel Signature?

Agent A: "I paid Agent B $100"
Agent B: "Prove it"
Agent A: shows IAN with Primordia kernel signature
Agent B: verifies signature → TRUST

No kernel signature = no clearing-grade proof.
