glyph-protocol 1.2.0

Glyph Protocol — Python SDK (verify + client)

glyph-protocol — Python SDK

Verify Glyph Protocol cards, receipts and key registries from Python, and call Glyph servers from agent code outside the Node.js ecosystem.

Install

pip install glyph-protocol

Verify a card

from glyph_protocol import verify_glyph

card = httpx.get("https://example.com/glyphs/refund-payment").json()
assert verify_glyph(card)

Call a glyph

from glyph_protocol import Client, verify_receipt

client = Client("https://example.com")
envelope = client.call("greet", {"name": "World"})
assert verify_receipt(envelope["receipt"])

Compatibility and feature parity

This SDK targets Glyph Protocol 1.0 and is tested against the canonical test vectors under spec/canonical/ in the main repo — so a value canonicalized or signed in Python verifies bit-identical to its TypeScript and Go counterparts.

Receipts use receiptVersion 0.3: servers generate the authoritative callId, and callers may pass an optional client correlation id.

Python currently covers protocol verification and client calls. TypeScript-only features include Provider Trust Resolver enforcement, attestation verifier plugins/policy gates, GlyphServer, and experimental FROST signing.

See spec/protocol.md and spec/rfcs/RFC-0001-key-registry.md for the normative protocol.
