Blockscout Explorer API Skill

Use this skill to run Blockscout explorer 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 a Blockscout deployment that exposes /api/v2.
• Access to the curated OpenAPI schema URL:

- https://raw.githubusercontent.com/holon-run/uxc/main/skills/blockscout-openapi-skill/references/blockscout-v2.openapi.json

• A target Blockscout instance. Examples in this skill use https://eth.blockscout.com/api/v2.

Scope

This skill covers a read-first explorer surface:

• address summary lookup
• address token balances
• address transaction history
• token metadata
• token holder reads
• transaction detail lookup
• block detail lookup

This skill does not cover:

• Blockscout GraphQL
• raw JSON-RPC proxying
• write operations or admin/configuration flows
• custom authenticated gateways beyond what the caller explicitly binds

Authentication

Public Blockscout instances usually allow explorer reads without auth.

If you are targeting a self-hosted or gateway-protected instance, configure auth separately with standard uxc auth bindings for that host. This skill does not assume any default credential.

Core Workflow

1. Use the fixed link command by default:

- command -v blockscout-openapi-cli - If missing, create it: uxc link blockscout-openapi-cli https://eth.blockscout.com/api/v2 --schema-url https://raw.githubusercontent.com/holon-run/uxc/main/skills/blockscout-openapi-skill/references/blockscout-v2.openapi.json - blockscout-openapi-cli -h

1. Inspect operation schema first:

- blockscout-openapi-cli get:/addresses/{address_hash} -h - blockscout-openapi-cli get:/tokens/{address_hash} -h - blockscout-openapi-cli get:/transactions/{hash} -h

1. Prefer narrow lookup validation before larger history reads:

- blockscout-openapi-cli get:/blocks/{block_number_or_hash} block_number_or_hash=latest - blockscout-openapi-cli get:/addresses/{address_hash} address_hash=0xd8da6bf26964af9d7eed9e03e53415d37aa96045 - blockscout-openapi-cli get:/tokens/{address_hash} address_hash=0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48

1. Execute with key/value parameters:

- blockscout-openapi-cli get:/addresses/{address_hash}/transactions address_hash=0xd8da6bf26964af9d7eed9e03e53415d37aa96045 - blockscout-openapi-cli get:/tokens/{address_hash}/holders address_hash=0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48

Operation Groups

Address Reads

• get:/addresses/{address_hash}
• get:/addresses/{address_hash}/token-balances
• get:/addresses/{address_hash}/transactions

Token, Transaction, And Block Reads

• get:/tokens/{address_hash}
• get:/tokens/{address_hash}/holders
• get:/transactions/{hash}
• get:/blocks/{block_number_or_hash}

Multi-Instance Use

To target a different Blockscout deployment, keep the same schema and relink the command to another host that serves /api/v2:

uxc link blockscout-openapi-cli https://optimism.blockscout.com/api/v2 \
  --schema-url https://raw.githubusercontent.com/holon-run/uxc/main/skills/blockscout-openapi-skill/references/blockscout-v2.openapi.json

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 transaction broadcast or contract write support.
• This schema is designed for Blockscout deployments that expose the explorer REST surface at /api/v2. If host help fails, check the deployment path before assuming a protocol mismatch.
• Pagination and filter options vary across deployments. Start with host help and operation help on the target instance before building large crawls.
• blockscout-openapi-cli <operation>... is equivalent to uxc <blockscout_api_v2_host> --schema-url <blockscout_openapi_schema> <operation>....
