description: Operate DefiLlama public analytics APIs through UXC with a curated OpenAPI schema and read-first guardrails.

DefiLlama Public API Skill

Use this skill to run DefiLlama public API operations through `uxc` + OpenAPI.

Reuse the `uxc` skill for shared execution, auth, and error-handling guidance.

Prerequisites

• `uxc` is installed and available in `PATH`.
• Network access to `https://api.llama.fi`.
• Access to the curated OpenAPI schema URL:
• `https://raw.githubusercontent.com/holon-run/uxc/main/skills/defillama-openapi-skill/references/defillama-public.openapi.json`

Scope

This skill covers a public read-only analytics surface on `api.llama.fi`:

• protocol TVL list
• per-protocol detail
• chain overview reads

This skill does **not** cover:

• write operations or account management
• DefiLlama Pro key-in-path auth
• split-host public services such as `coins.llama.fi` and `yields.llama.fi`
• the full DefiLlama public API surface

Authentication

This public skill does not require authentication.

Core Workflow

1. Use the fixed link command by default:

• `command -v defillama-openapi-cli`
• If missing, create it:

`uxc link defillama-openapi-cli https://api.llama.fi --schema-url https://raw.githubusercontent.com/holon-run/uxc/main/skills/defillama-openapi-skill/references/defillama-public.openapi.json`

• `defillama-openapi-cli -h`

2. Inspect operation schema first:

• `defillama-openapi-cli get:/protocols -h`
• `defillama-openapi-cli get:/protocol/{protocol} -h`
• `defillama-openapi-cli get:/v2/chains -h`

3. Prefer narrow read validation before broader reads:

• `defillama-openapi-cli get:/v2/chains`
• `defillama-openapi-cli get:/protocols`
• `defillama-openapi-cli get:/protocol/{protocol} protocol=aave`

4. Execute with key/value parameters:

• `defillama-openapi-cli get:/protocol/{protocol} protocol=aave`
• `defillama-openapi-cli get:/v2/chains`

Operations

• `get:/protocols`
• `get:/protocol/{protocol}`
• `get:/v2/chains`

Guardrails

• Keep automation on the JSON output envelope; do not use `--text`.
• Parse stable fields first: `ok`, `kind`, `protocol`, `data`, `error`.
• Treat this v1 skill as read-only. Do not imply wallet, trading, or admin support.
• Public DefiLlama data is split across multiple hosts. This skill intentionally stays on `api.llama.fi`; use the separate Pro skill when you need the unified Pro host.
• `defillama-openapi-cli <operation> ...` is equivalent to `uxc https://api.llama.fi --schema-url <defillama_openapi_schema> <operation> ...`.
