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:

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:

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

Core Workflow

1. Use the fixed link command by default:
2. command -v moralis-openapi-cli
3. 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

4. moralis-openapi-cli -h

5. Inspect operation schema first:

6. moralis-openapi-cli get:/{address}/balance -h
7. moralis-openapi-cli get:/wallets/{address}/tokens -h

8. moralis-openapi-cli get:/erc20/{address}/price -h

9. Prefer narrow reads before broader wallet scans:

10. moralis-openapi-cli get:/{address}/balance address=0xd8da6bf26964af9d7eed9e03e53415d37aa96045 chain=eth
11. moralis-openapi-cli get:/erc20/{address}/price address=0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48 chain=eth

12. moralis-openapi-cli get:/wallets/{address}/net-worth address=0xd8da6bf26964af9d7eed9e03e53415d37aa96045 chain=eth

13. Execute with key/value parameters:

14. moralis-openapi-cli get:/wallets/{address}/tokens address=0xd8da6bf26964af9d7eed9e03e53415d37aa96045 chain=eth
15. 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> ....
