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

DefiLlama Yields API Skill

Use this skill to run DefiLlama public yield 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://yields.llama.fi`.
• Access to the curated OpenAPI schema URL:
• `https://raw.githubusercontent.com/holon-run/uxc/main/skills/defillama-yields-openapi-skill/references/defillama-yields.openapi.json`

Scope

This skill covers a public read-only yield surface on `yields.llama.fi`:

• yield pool discovery
• per-pool chart history

This skill does **not** cover:

• write operations
• protocol or chain overview endpoints from `api.llama.fi`
• price endpoints from `coins.llama.fi`
• DefiLlama Pro APIs

Authentication

This public skill does not require authentication.

Core Workflow

1. Use the fixed link command by default:

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

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

• `defillama-yields-openapi-cli -h`

2. Inspect operation schema first:

• `defillama-yields-openapi-cli get:/pools -h`
• `defillama-yields-openapi-cli get:/chart/{pool} -h`

3. Prefer narrow read validation before broader reads:

• `defillama-yields-openapi-cli get:/pools`
• `defillama-yields-openapi-cli get:/chart/{pool} pool=747c1d2a-c668-4682-b9f9-296708a3dd90`

Operations

• `get:/pools`
• `get:/chart/{pool}`

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.
• Public DefiLlama data is split across multiple hosts; this skill intentionally wraps only `yields.llama.fi`.
• `defillama-yields-openapi-cli <operation> ...` is equivalent to `uxc https://yields.llama.fi --schema-url <defillama_yields_openapi_schema> <operation> ...`.
