@blockscout/api-types

TypeScript types generated from Blockscout OpenAPI specs via openapi-typescript:

• publicApi — default public API (BlockScoutWeb.Specs.Public, no CHAIN_TYPE)
• privateApi — account API (BlockScoutWeb.Specs.Private)
• chain namespaces — chain-specific public API (CHAIN_TYPE set; matches generate-swagger.yml, excluding deprecated MUD)

Build artifacts (openapi/, dist/) are gitignored; run npm run build after clone.

Prerequisites

• Elixir / Mix at the Blockscout repo root (compiled block_scout_web app)
• Node.js 18+ (for openapi-typescript)

Generate

From this directory:

npm install
npm run build

build runs:

• generate:spec — mix openapi.spec.yaml for public, private, and each chain type
• generate:types — openapi-typescript writes matching files under dist/

Usage

Types are grouped by spec name in the package entry:

import type { publicApi, privateApi, arbitrum, optimismCelo } from "@blockscout/api-types";

type AddressResponse = publicApi.components["schemas"]["AddressResponse"];

type GetAddressParams =
  publicApi.paths["/v2/addresses/{address_hash_param}"]["get"]["parameters"];

type ArbitrumPath = arbitrum.paths[keyof arbitrum.paths];

publicApi / privateApi avoid TypeScript reserved words (public, private). optimism-celo is exported as optimismCelo (hyphen is invalid in identifiers).

Point your app at this package via file:../types-package or your monorepo workspace.

Chain types

Synced with .github/workflows/generate-swagger.yml via scripts/chain-types.sh:

arbitrum, arc, blackfort, ethereum, filecoin, neon, optimism, optimism-celo, rsk, scroll, shibarium, stability, suave, zetachain, zilliqa, zksync

When CI adds or removes a chain type, update scripts/chain-types.sh and index.ts.
