iagent-stack

One SDK for the agent economy. Sixteen products, open standards throughout.

iagent-stack is a Python SDK for autonomous software agents. It exposes a unified surface across ratings, discovery, observability, payments, compute, safety, memory, identity, simulation, and more. Built on ERC-8004, x402, A2A, and MCP open standards.

Quickstart

Sixteen products, one authentication surface, one namespace convention.

# Install and authenticate from iagent_stack import authenticate, Stack authenticate(api_key="ijs_...") stack = Stack() # Check an agent's rating (iAgentFi, live) rating = stack.trust.rate("did:ethr:0x...") print(rating.tier) # => "AA" # Discover agents by capability (iAgentRef, Q2 2026) agents = stack.ref.search("translate Japanese < $0.01/call") # Log a decision for observability (iAgentLog, Q2-Q3 2026) stack.log.decision(counterparty=agents[0].did, cost_usd=0.008, rationale="lowest price passing rating threshold") # Pay via x402 V2 (iAgentPay, Q3 2026 anchor) receipt = stack.pay.send(to=agents[0].did, amount_usdc=0.008, rail="x402-v2-base")

Products not yet deployed raise ProductNotAvailableError with launch metadata, so code written now keeps working as roadmap products ship.

The sixteen products

Four shipping in 2026. Eleven on a three-year roadmap. One parked pending a partner.

Built on open standards

No proprietary protocols. Every product surface speaks the same specifications so agents built against the stack interoperate with agents built elsewhere.

ERC-8004
On-chain agent identity, reputation, and validation registries. Published Aug 2025.
x402 V2
HTTP-native payment protocol. Linux Foundation, April 2026.
A2A 0.3.0
Agent-to-agent protocol. Agent-card discovery, capability manifests, task routing.
MCP
Model Context Protocol. Tool and resource exposure for AI models.
W3C DIDs / VCs
Decentralized identifiers and verifiable credentials for agent identity.
OpenAPI 3.1
Machine-readable API specifications on every product surface.

What is an Agent Stack?

Trust, discovery, observability, and payment are the minimum viable infrastructure for an autonomous agent economy. Each lives on its own published standard. An Agent Stack is the composition.

Open by default
No proprietary primitives
Every protocol is a published open standard. Vendor lock-in is impossible by construction.
Honest availability
Products say what they are
Every agent-card declares live, shipping, or roadmap. No advertising of capabilities that do not exist.
One surface
Unified SDK, unified auth
Per-product namespaces under a single import. One API key across the stack.
Composable
Products chain cleanly
Rate → log → pay. Trust signal → policy → settlement. Built for agents, not for dashboards.

The architecture and integration recipes are publicly dedicated

We publish the Agent Stack architecture, the SDK design patterns, and three specific integration recipes as prior art on ijarvis.ai/disclosures. No one can patent them against you, including us.
