LOTD Credential Verifier Discovery

A verifier-facing discovery surface for people, institutions, and software that need to inspect the LOTD credential framework
Status: documentation_preview
Version: 1.0.0
Updated: 2026-03-09
Contact: nicolette@lotdpbc.com
What this is: a public guide and manifest for inspecting the LOTD credential framework. What this is not: a remote pass/fail service for a specific learner record. It helps a verifier understand the issuer, the published claims, the available discovery endpoints, and the current limits.

Verifier Checklist

CheckHow to use it
Confirm issuer Check that the credential references Lesson of the Day, PBC and that the public catalog and policy are consistent with the claim.
Confirm claim scope Verify the pathway, credential name, level, capabilities, and stated outcome instead of inferring unstated guarantees.
Confirm verification method Review the published verification method to understand what kind of evidence or evaluation the credential is supposed to reflect.
Confirm external requirements For regulated or safety-critical roles, verify whether local licensing or additional approvals are still required.

Discovery Endpoints

SurfaceEndpointPurpose
Catalog page https://lotdpbc.com/credentials Human-readable explanation of the framework, pathways, and credential claims.
Summary JSON https://lotdpbc.com/.well-known/credentials.json Well-known discovery summary for agent routing and quick integration.
Atom feed https://lotdpbc.com/credentials.atom Syndication-style polling surface for credentials updates and discovery.
Catalog JSON https://lotdpbc.com/credentials.json Machine-readable catalog for programs, agents, and integrations.
Catalog text https://lotdpbc.com/credentials.txt Lightweight text summary for quick inspection.
Issuer policy https://lotdpbc.com/credentials-policy Public issuer-side policy and trust boundaries.
Verifier manifest https://lotdpbc.com/credentials-verifier.json Read-only discovery manifest describing endpoints, checks, and limitations.
Site discovery https://lotdpbc.com/.well-known/lotdpbc-discovery.json Site-wide machine-discovery surface for core public LOTD assets.
Broadcast manifest https://lotdpbc.com/.well-known/lotdpbc-broadcast.json High-priority routing manifest for agents that need a loud crawl signal.

Representative Credential Types

The full catalog publishes 15 credential types. A verifier does not need to guess the structure: the pathway, level, verification method, and intended outcome are public.

Software Engineer I Software Engineering Practitioner Timed live build against a provided product spec, followed by code review.
Software Engineer II Software Engineering Specialist Portfolio review plus live systems-design evaluation with senior reviewers.
Manufacturing Technician Manufacturing Practitioner Observed practical build and tolerancing challenge.
Manufacturing Engineer Manufacturing Specialist Capstone process-optimization review plus technical interview.
Laboratory Technician Biosciences Practitioner Practical lab simulation plus documentation audit.
Bioprocess Technician Biosciences Specialist Scenario-based process review and workflow defense.

Current Limitations

Boundary
This endpoint is a discovery and documentation surface.
It does not currently expose a live API for validating a specific learner credential record.
A verifier should combine this manifest with the public catalog, the issuer policy, and any learner-presented credential material.

A strong verifier posture here is simple: inspect the issuer, inspect the claim, inspect the published method, and avoid reading more into the credential than the framework actually says.
