Arbiscan

Arbiscan is the official blockchain explorer, search, API, and analytics platform for Arbitrum One, the leading Ethereum Layer 2 scaling network. It enables developers and users to query Arbitrum One transaction histories, token transfers (ERC-20, ERC-721, ERC-1155), smart contract source code and ABIs, block data, and L2 network statistics. The Arbiscan API is part of the Etherscan unified V2 platform, accessible across 60+ EVM-compatible chains with a single API key. A free tier provides 100,000 daily calls at 3 requests per second; paid tiers scale up to enterprise with unmetered access.

agent ready

Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.

Kin Score

API Evangelist profiles Arbiscan the way a machine reads it — 16 machine-readable artifacts across 8 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.

Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Arbiscan scores 49.8/100 (developing), with a separate agent-readiness read of 48/100 (agent ready). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.

Kin Score

This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Arbiscan

Each block below is one kind of artifact we hold for Arbiscan. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.

APIs 8

Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Individual APIs this provider publishes, each with its own machine-readable definition.

Arbiscan Accounts API

Address balances, transactions, token holdings, and funding origins

Arbiscan Blocks API

Block details, rewards, countdown, and block-by-timestamp lookup

Arbiscan Contracts API

Smart contract source code, ABI, creation info, and verification

Arbiscan Gas Tracker API

Arbitrum One gas oracle and gas price estimates

Arbiscan Logs API

Event log queries by address, topic, and block range

Arbiscan Stats API

Arbitrum One network statistics, supply data, and daily metrics

Arbiscan Tokens API

ERC-20, ERC-721, and ERC-1155 token supply, holders, and metadata

Arbiscan Transactions API

Transaction status, receipts, counts, and advanced filtering

Pricing Plans 1

Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the six things the Kin Score reads for commercial clarity.

Published pricing tiers and plan structures.

Rate Limits 1

Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.

Documented rate limits and quota policies.

FinOps 1

Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.

Cost, billing, and metering signals for API financial operations.

Semantic Vocabularies 1

JSON-LD contexts give the data shared meaning across APIs. We profile them because semantics are what let a machine reconcile 'customer' here with 'customer' somewhere else.

JSON-LD contexts and semantic vocabularies used across these APIs.

Security Posture 3

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

Agentic Access 1

An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
