DefiLlama OpenAPI Skill

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 ... is equivalent to uxc https://api.llama.fi --schema-url ....
