Verify a QLM Profile share.

A candidate sent you a Profile share. Before you trust it as evidence, you want to verify it's genuine — that QLM actually issued it, that the candidate didn't forge or alter it, that it's still active. The verification infrastructure is public, free, and works without QLM account creation. Cryptographic verification of every share, with five distinct checks plus methodology version alignment.

◆ Verification view · 01

Five checks. Cryptographic, time-anchored.

Paste the share token or follow the share link. The verification page returns five checks plus the Profile content the share is authorized to display. If any check fails, the page returns "verification failed" with a specific reason — the recipient sees clearly that the share is invalid, expired, revoked, or otherwise not trustworthy.

◆ PUBLIC VERIFICATION · QUANTUMLEARNINGMACHINES.COM/VERIFY

QLM Profile verification

Share token: 3dkX9rQ... · Recipient: hiring@acme-corp.com · Issued: April 28, 2026 · 14:32 EST

✓ This Profile share is genuine. All five verification checks passed. Issued by QLM, not revoked, within expiration, methodology aligned.

✓ Signature valid — share signed by QLM key kid:2026-Q1, EdDSA. Signature mathematically verifies against QLM's published public key. Verified

✓ Key valid at signing time — the QLM signing key was active at the moment this share was issued (April 28, 2026 · 14:32 EST). Verified

✓ Not revoked — the issuer (Maya Reyes, qlm-id CR-71f3d2a) has not revoked this share. Revocation status checked just now against the public revocation endpoint. Active

✓ Within expiration — the share is set to expire on May 28, 2026. Currently 29 days remaining. Active

✓ Methodology aligned — Profile is aligned with QLM methodology version 1.0 published April 28, 2026. Methodology document available at quantumlearningmachines.com/research/methodology/v1.0. Aligned

What verification means: the share is genuine, the candidate didn't forge it, and it's still authorized. What verification does not mean: the Profile fits the role you're hiring for, the candidate is the right hire, or you should rely on this evidence over your judgment. Verification confirms authenticity, not interpretation.

Real verification, real cryptographic checks, real recipient infrastructure. This is what trust looks like when it's a public good.

◆ How it works · 02

Three integration paths. For three recipient types.

Recipients verify shares in different ways depending on their workflow. Three integration paths: web verification page for ad-hoc verification, REST API for systems integration, and ATS/HRIS partner integrations for inline verification.

i. Web page

Recipient pastes the share token or follows the share link. Five checks complete in <5 seconds. No account required.

ii. Public API

REST endpoint at /v1/verify. Standard JWT verification tooling supported. 10K queries / hour rate limit free; higher tiers paid.

iii. Partner inline

ATS / HRIS partners surface verification inline in the candidate record. Recipient sees verification status without leaving their workflow.

◆ Methodology · 03

Public verification as public good.

QLM's commitment is that verification works without QLM account creation, without payment, without rate-limiting that excludes legitimate small-volume recipients. The verification infrastructure exists primarily to support the brand's portability commitment — Profile share without verification is not really portable. Standard public-key cryptography, well-understood signature algorithm, no proprietary protocols.

◆ SIGNATURE

EdDSA

ed25519 signing for every Profile artifact. Standard JWT tooling supported across languages. Public key published at well-known URL; key history available for historical share verification.

◆ RATE LIMIT

10K/hr free

Generous free tier supports legitimate small-volume recipient use cases. Higher tiers available for high-volume integrations (e.g., ATS surfacing verification on every candidate record).

◆ UPTIME

99.95%

Verification API SLA. If verification is offline, share recipients can't establish trust — uptime is foundational to the brand commitment, not a luxury feature.

◆ The honest read · 04

What verification does and does not establish.

Verification establishes that the Profile is genuine and authorized for display. It does not interpret the Profile, recommend hiring decisions, or replace the recipient's judgment. Five things verification does not do.

Tell you whether to hire the candidate. Verification confirms authenticity. Whether the Profile fits the role, the team, the moment is the recipient's judgment — verification is necessary but not sufficient for hiring.
Architectural
Interpret what the Profile means. Verification returns the Profile content; the methodology accessibility surface explains what each dimension measures. Recipients without context can drill into methodology, but interpretation remains the recipient's work.
Methodology
Establish the candidate's identity. Verification confirms the Profile is genuinely issued by QLM to the qlm-id holder. Confirming the qlm-id holder is the same person sitting in front of you is your interview process, not QLM's verification.
Boundary
Replace background checks or references. Capability evidence is one input; character, work history, fit are different evidence types verification doesn't address. Calibrated capability is a piece of the picture, not the picture.
Architectural
Guarantee the candidate isn't gaming the system. Profile evidence is calibrated, fairness-audited, and resistant to obvious gaming. It is not impossible to game; the brand commitment is to disclose this honestly rather than oversell verification as anti-gaming.

◆ Pricing · 05

Free for recipients. Always.

Verification is free for recipients. The portability commitment requires it. Higher-volume integrations (ATS partners, large-scale verification deployments) tier into paid plans for SLA and rate-limit upgrades; small-volume legitimate recipient use is free.

◆ FREE TIER

Public verification.

$0 / always

Web page + REST API verification, 10K queries/hour, no account required. Covers the vast majority of legitimate recipient use cases. Foundational to the brand commitment; not pricing-experiment territory.

No credit card required

◆ HIGH-VOLUME

Verification tier.

$0.01-0.05 per query

For very high-volume integrations beyond 10K/hour. Includes 99.99% SLA, dedicated rate-limit pool, support for cached verification. Useful only for ATS partners, recruiting platforms with massive verification load.

Volume discounts available

◆ PARTNER

Inline integration.

Custom per partner

ATS / HRIS partners that surface verification inline in their candidate workflow. Negotiated case-by-case with OEM partnership tier.
