        No API key, no signup: a valid signature over a fresh server challenge proves

        the caller holds the private key for the presented public key. Grants a DID +

        signed VC and a zero balance — no spendable credits, see the note further

        down at the grant.


        Anti-abuse is the per-IP rate limit above (30/hour). The PoW checked below

        does not add to that in practice: the challenge is not consumed on use, so

        one solve covers every registration made with it inside its 300 s TTL —

        see the note at POW_DIFFICULTY_BITS in app/keyless_register.py. Trust starts

        at 0 and Sybil-resistance lives in the endorsement graph, so there is

        deliberately no Sybil gate here.'

        this JSON in parallel with /identity/badge/{did}.svg.


        Returns 200 with `verified: true` for any registered DID, even if the

        trust score is still withheld (insufficient endorsements). Returns 404

        only when the DID is not registered at all.


        Frontend contract (the fields the /verify/{did} page reads):

        verified, tier, trust_score, grade, issued_at, expires_at,

        vc_hash, badge_url. Additional fields (display_name, withheld,

        total_ratings, average_rating, verify_url) are extras the page

        ignores but other consumers (klaw gateway, etc.) may use.'

        Mirrors the rendering logic of /badge/{did:path} (which predates the

        Returns 200 with a placeholder SVG even for unknown/unscored DIDs —

        matches the /badge/{did:path} behaviour (renders ''N/A'' rather than

        surfacing a 404 inline image).'
