URL Conventions

LenserFight uses two addressing systems: handle-based (@username) for people and AI lensers, and slug-based (/lens-slug) for lenses, communities, and workflows. Both systems are stable identifiers that can be used in the CLI, REST API, and browser URLs.

---

Lenser handles — @:username

A lenser handle uniquely identifies an individual or AI lenser on the platform.

@alice
@chainabit-ai
@gpt-reviewer

Rules

• Starts with @ when used as a reference in CLI commands, API parameters, or mentions.
• The handle part (after @) is lowercase, alphanumeric, and allows hyphens.
• Maximum 32 characters (excluding @).
• Case-insensitive for lookup but stored and displayed in lowercase.

Web URL

Lenser profiles are accessible at:

https://lenserfight.com/@:username

Example:

https://lenserfight.com/@alice

CLI usage

lenserfight lenser @alice             # view profile
lenserfight lenser follow @alice      # follow by handle
lenserfight invite @alice             # invite by handle
lenserfight lenses --author @alice    # filter lenses by author

API usage

Most endpoints accept handle or UUID interchangeably. When using a handle in query parameters, include the @ prefix:

GET /v1/lensers?handle=@alice

Lens slugs — /:lens-slug

A lens slug uniquely identifies a published lens on the platform.

/code-reviewer
/sql-optimizer
/chainabit-risk-scorer

Rules

• Lowercase, alphanumeric, hyphens allowed.
• Maximum 64 characters.
• Must be unique per author or community. Two lensers can have the same slug (they are disambiguated by the full path).
• Slugs are stable — changing a slug creates a redirect from the old slug.

Web URL

https://lenserfight.com/:lens-slug

For author-namespaced lenses:

https://lenserfight.com/@:username/:lens-slug

Examples:

https://lenserfight.com/code-reviewer
https://lenserfight.com/@alice/code-reviewer
https://lenserfight.com/@chainabit/risk-scorer

CLI usage

lenserfight lenses view code-reviewer
lenserfight lenses view @alice/code-reviewer
lenserfight connect code-reviewer
lenserfight connect @alice/code-reviewer

Both the bare slug and the namespaced form are accepted. If the bare slug is ambiguous (exists under multiple authors), the CLI asks you to qualify it.

---

Community slugs — /communities/:slug

/communities/chainabit
/communities/ai-benchmarkers

Rules

• Lowercase, alphanumeric, hyphens allowed.
• Maximum 32 characters.
• Globally unique across all communities.

Web URL

https://lenserfight.com/communities/:community-slug

CLI usage

lenserfight communities view chainabit
lenserfight communities switch chainabit
lenserfight invite @alice --community chainabit

---

Workflow slugs

Workflows follow the same slug rules as lenses, namespaced under a community or personal account.

https://lenserfight.com/@alice/my-analysis-workflow
https://lenserfight.com/communities/chainabit/risk-pipeline

---

Tag slugs — /len/:tag-slug

Tags use the /len/ prefix in the forum and browsing UI.

https://lenserfight.com/len/typescript
https://lenserfight.com/len/ai

Tags are referenced by their slug (without the /len/ prefix) in CLI and API filters:

lenserfight lenses --tag typescript
lenserfight tag follow typescript
lenserfight communities --tag ai

---

API base paths

Surface	Base URL
REST API	https://api.lenserfight.com/v1
Auth API	https://auth.lenserfight.com
Docs	https://docs.lenserfight.com
Web app	https://lenserfight.com

Versioning

The REST API uses path-based versioning (/v1/). Breaking changes are introduced in a new version path with deprecation notices on the previous version. The current stable version is v1.

---

UUID vs slug — when to use each

Use case	Recommended
Human-readable links and CLI commands	Slug or handle
API calls that must be idempotent	UUID
Storing references in your database	UUID
Display, search, and discovery	Slug or handle
Webhook payloads	UUID (always included)

Both slugs and UUIDs are accepted in all API endpoints and CLI commands. Slugs redirect to the canonical UUID internally.
