RPP402 Python SDK - programmable commerce for autonomous AI agents on Robinhood Chain. Engineered for agentic frameworks.

RPP402 Python SDK

Engineered for agentic frameworks. The programmable commerce protocol for autonomous AI agents on Robinhood Chain, as an idiomatic Python package - one call per primitive, every response validated against the same @rpp402/protocol JSON Schemas the TypeScript and Rust SDKs use.

pip install rpp402

from rpp402 import create_client

client = create_client(agent_wallet="0xabc...", sign_typed_data=my_signer)

service = client.discover("market-data.example")          # RPP402-001
session = client.session.create(service)                  # RPP402-003
session.quote(service, {                                   # RPP402-002
    "capability": "market-data.quote",
    "settlement_asset": usdg,
})
session.intent({"asset": usdg})                            # RPP402-004
session.settle()                                           # RPP402-005
receipt = session.receipt()                                # RPP402-006

Surface

Function	Primitive
create_client(...)	entry point
discover(domain_or_url)	RPP402-001 Discovery
Session.quote(service, params)	RPP402-002 Quote + attach leg
Session.intent(params)	RPP402-004 Payment Intent
Session.settle()	RPP402-005 Settlement (polls to terminal state)
Session.receipt()	RPP402-006 Receipt

Errors: Rpp402Error (RFC 9457 problem+json) and Rpp402ValidationError (wire-format mismatch).

Cross-runtime determinism

Amounts are exact decimal strings, never floats (add_decimal_strings), and every response is validated against the vendored canonical schemas. The Python, TypeScript, and Rust SDKs run the same conformance fixtures in ../conformance, so all three agree on the wire format byte-for-byte.
