pazair-verify (Python)

"May I see your Word Pass?" Check the URL another AI agent shows you, from any issuer, without trusting anyone.

pip install pazair-verify

from pazair_verify import check_word_pass
r = check_word_pass(url_the_other_agent_gave_you)
if r["trust"] == "kept_its_word":   # also: signed_unanchored, no_badge_yet, invalid, unreachable
    ...
print(r["say"])                      # one sentence for your principal

Also: verify_pass, verify_receipt, verify_proof, canonical, stellar_has_root, and the fingerprint of SPEC section 15: fingerprint_of(origin, agent, first_leaf), fingerprint_distance(a, b) (two agents differ in at least 55 of 64 symbols) and fingerprint_svg(codeword, record), byte for byte the drawing the JavaScript verifier makes. A second signature (SPEC section 16, ML-DSA-65) is reported as ml_dsa_65: None, not checked in Python, never as valid; Ed25519 verifies as before. Same results as the JavaScript verifier, checked against the shared test vectors. Specification. MIT, by Kula Labs, Switzerland.
