AI-assisted integration

Use AI coding agents to integrate Devolens (formerly Cryptolens) faster. Install the full Devolens skill bundle rather than a single skill. The language-specific skills depend on cryptolens-sdk-common.

Claude Code
Codex
Other agents

Install from the Claude plugin marketplace:

/plugin marketplace add Cryptolens/skills
/plugin install devolens@devolens

This installs all twelve skills in the bundle. To pull new versions later, refresh the marketplace with /plugin marketplace update devolens.If you need a manual fallback, copy the folders from the repo’s skills/ directory into .claude/skills/ or ~/.claude/skills/, then start a new Claude Code session.Try:

Use the license-offline skill to help me add cached offline license verification to this project.

Install the Devolens Codex marketplace:

curl -fsSL https://raw.githubusercontent.com/Cryptolens/skills/main/install.sh | bash

Restart Codex, open Plugin Directory, then install Devolens Licensing (devolens).The installer places a local marketplace at $CODEX_HOME/marketplaces/devolens, defaulting to ~/.codex/marketplaces/devolens when CODEX_HOME is not set. It registers Devolens as a marketplace source in $CODEX_HOME/config.toml. If you prefer not to run the remote script directly, download github.com/Cryptolens/skills and run scripts/install_codex_marketplace.sh locally.Try:

Use the license-key-verification skill to help me add license key verification with cached offline fallback to this project.

If your agent does not support skills directly, load the llms.txt files below.

Let your agent access your account

The skills and llms.txt files on this page help an agent write your integration code. If you also want the agent to act on your live account, query usage analytics, look up customers, or manage license keys, connect the Devolens MCP server. Access is limited to the permissions you grant during authorization, or to those of the access token you connect with.

Documentation for AI agents

Load these files to give your agent full context of Devolens (formerly Cryptolens) Web API, license models, use cases and best practises.

Filename	Summary	When to use
llms.txt (Documentation)	Structured index of the documentation page hosted at help.cryptolens.io.	Answering queries on how to get started with e.g. key verification in different languages, available licensing models and best practises.
llms-full.txt (Documentation)	Completed documentation of all pages hosted at help.cryptolens.io.	When you need the full context (see above).
llms.txt (Web API)	Structured index of the Web API documentation page. It’s language agnostic but provides vital information about each API endpoint.	Answering queries that are not covered by our documentation. This is the source of truth of how the API endpoints work. It’s recommended when you are implementing a license flow not covered by examples, or when you need to implement advanced features, such as “field masking” for privacy/compliance reason, understanding of how to configure access tokens for advanced use cases, and more.
llms-full.txt (Web API)	Completed documentation of the Web API (see above).	When you need the full context (see above).

Starter prompts

Use outcome-based prompts rather than asking for a generic Devolens overview.

Goal	Prompt
Add license checks	`Use the license-key-verification skill to add Devolens license key verification to this project.`
Add offline support	`Use the license-offline skill to add cached offline license verification to this project.`
Add trials	`Use the license-trials skill to add a verified trial license flow to this project.`
Gate features	`Use the license-feature-gates skill to add feature-gated licensing for these modules: ...`
Add subscriptions	`Use the license-subscriptions skill to add subscription expiry checks and renewal handling.`
Add floating seats	`Use the license-floating skill to add floating license support with safe overdraft defaults.`

Automate payments	`Use the license-payment-automation skill to integrate Devolens with Stripe, n8n, Zapier, or another external payment provider.`

Before publishing, ask your agent to review the integration with the license-key-verification skill. See Checklist before publishing.
