What it does

Moralis Openapi Skill is an agent skill from holon-run/uxc. Operate Moralis EVM wallet and token reads through UXC with a curated OpenAPI schema, API-key auth, and wallet-intelligence guardrails.

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts and reference files (for example `agents/openai.yaml`, `references/moralis-evm.openapi.json` and `references/usage-patterns.md`).

It sits in Backend & APIs, covering OpenAPI specifications and Smart contracts. It works with OpenAPI and Ethereum. The repository describes itself as: A unified CLI for discovering and invoking tools across OpenAPI, MCP, GraphQL, gRPC, and JSON-RPC. The licence is MIT.

When your agent uses it

  • Tasks that involve OpenAPI specifications
  • Tasks that involve Smart contracts

Example prompts

  • “/moralis-openapi-skill”

Requirements

  • A Bash shell
  • A credential in MORALIS_API_KEY

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Use the fixed link command by default
  2. Inspect operation schema first
  3. Prefer narrow reads before broader wallet scans
  4. Execute with key/value parameters

What it can do on your machine

Read from SKILL.md and the folder at commit 562d47c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Shell), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • deep-index.moralis.io

    Also links to:

    • docs.moralis.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • MORALIS_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Moralis Openapi Skill loads about 1k tokens when it runs, and up to ~3.4k if it reads all its reference files. Until then it costs about 39 tokens; SKILL.md has 300 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~39
When it runs · the whole SKILL.md, loaded when a task matches
~1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Moralis Web3 Data API Skill

Use this skill to run Moralis EVM data 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://deep-index.moralis.io/api/v2.2.
  • Access to the curated OpenAPI schema URL:
    • https://raw.githubusercontent.com/holon-run/uxc/main/skills/moralis-openapi-skill/references/moralis-evm.openapi.json
  • A Moralis API key.

Scope

This skill covers a read-first wallet intelligence surface:

  • native balance lookup
  • wallet token balances
  • wallet history
  • wallet swaps
  • wallet net worth
  • ERC-20 metadata lookup
  • ERC-20 token price lookup

This skill does not cover:

  • write or transaction submission flows
  • Solana, Streams, or NFT-specific surfaces
  • the full Moralis API

Authentication

Moralis uses X-API-Key header auth.

Configure one API-key credential and bind it to deep-index.moralis.io/api/v2.2:

bash
uxc auth credential set moralis \
  --auth-type api_key \
  --api-key-header X-API-Key \
  --secret-env MORALIS_API_KEY

uxc auth binding add \
  --id moralis \
  --host deep-index.moralis.io \
  --path-prefix /api/v2.2 \
  --scheme https \
  --credential moralis \
  --priority 100

Validate the active mapping when auth looks wrong:

bash
uxc auth binding match https://deep-index.moralis.io/api/v2.2

Core Workflow

  1. Use the fixed link command by default:

    • command -v moralis-openapi-cli
    • If missing, create it: uxc link moralis-openapi-cli https://deep-index.moralis.io/api/v2.2 --schema-url https://raw.githubusercontent.com/holon-run/uxc/main/skills/moralis-openapi-skill/references/moralis-evm.openapi.json
    • moralis-openapi-cli -h
  2. Inspect operation schema first:

    • moralis-openapi-cli get:/{address}/balance -h
    • moralis-openapi-cli get:/wallets/{address}/tokens -h
    • moralis-openapi-cli get:/erc20/{address}/price -h
  3. Prefer narrow reads before broader wallet scans:

    • moralis-openapi-cli get:/{address}/balance address=0xd8da6bf26964af9d7eed9e03e53415d37aa96045 chain=eth
    • moralis-openapi-cli get:/erc20/{address}/price address=0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48 chain=eth
    • moralis-openapi-cli get:/wallets/{address}/net-worth address=0xd8da6bf26964af9d7eed9e03e53415d37aa96045 chain=eth
  4. Execute with key/value parameters:

    • moralis-openapi-cli get:/wallets/{address}/tokens address=0xd8da6bf26964af9d7eed9e03e53415d37aa96045 chain=eth
    • moralis-openapi-cli get:/wallets/{address}/history address=0xd8da6bf26964af9d7eed9e03e53415d37aa96045 chain=eth limit=20

Operation Groups

Wallet Reads
  • get:/{address}/balance
  • get:/wallets/{address}/tokens
  • get:/wallets/{address}/history
  • get:/wallets/{address}/swaps
  • get:/wallets/{address}/net-worth
Token Reads
  • get:/erc20/metadata
  • get:/erc20/{address}/price

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 signing or transaction broadcast support.
  • Moralis supports multiple chains. Always pass chain explicitly instead of assuming Ethereum.
  • Wallet history and swaps can become expensive at large ranges. Start with small limits and narrow time windows.
  • moralis-openapi-cli <operation> ... is equivalent to uxc https://deep-index.moralis.io/api/v2.2 --schema-url <moralis_openapi_schema> <operation> ....
