Blockscout
Blockscout is an open-source EVM blockchain explorer covering 1,000+ L1, L2, and L3 EVM chains. Each Blockscout instance exposes a REST v1 API (legacy), REST v2 API (recommended), GraphQL API, and an Etherscan-compatible API. The hosted Blockscout PRO API at dev.blockscout.com provides multi-chain access with unified routes, plans, and credit-based metering.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Blockscout the way a machine reads it — 40 machine-readable artifacts across 1 API, 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 — Blockscout scores 27.4/100 (thin), with a separate agent-readiness read of 22/100 (agent aware). 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. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Blockscout
Each block below is one kind of artifact we hold for Blockscout. 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 18
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.
Blockscout REST API v2
Recommended REST API on each Blockscout instance. Endpoints cover blocks, transactions, addresses, tokens, smart-contract verification, and more. Path varies by chain (eth, opti...
Blockscout GraphQL API
GraphQL API exposing blocks, transactions, addresses, and tokens.
Blockscout Etherscan-Compatible API
Drop-in Etherscan-style RPC API (action / module query parameters) for easy migration.
Blockscout PRO API
Hosted multi-chain Blockscout API with unified routes, plans, and credit-based metering. Replaces the older MyAccount API; old keys do not work on PRO routes.
Blockscout Addresses API
The Addresses API from Blockscout — 15 operation(s) for addresses.
Blockscout Blocks API
The Blocks API from Blockscout — 4 operation(s) for blocks.
Blockscout CelestiaService API
The CelestiaService API from Blockscout — 3 operation(s) for celestiaservice.
Blockscout Config API
The Config API from Blockscout — 1 operation(s) for config.
Blockscout Internal Transactions API
The Internal Transactions API from Blockscout — 1 operation(s) for internal transactions.
Blockscout Main Page API
The Main Page API from Blockscout — 3 operation(s) for main page.
Blockscout Proxy API
The Proxy API from Blockscout — 1 operation(s) for proxy.
Blockscout Search API
The Search API from Blockscout — 2 operation(s) for search.
Blockscout Smart Contracts API
The Smart Contracts API from Blockscout — 3 operation(s) for smart contracts.
Blockscout Stats API
The Stats API from Blockscout — 3 operation(s) for stats.
Blockscout Token Transfers API
The Token Transfers API from Blockscout — 1 operation(s) for token transfers.
Blockscout Tokens API
The Tokens API from Blockscout — 11 operation(s) for tokens.
Blockscout Transactions API

GraphQL 1
Where a provider ships GraphQL, the schema is the contract. We profile it alongside the REST surface so the whole interface is legible in one place.
GraphQL schemas published by this provider.
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 things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.
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.
Blockscout Rate Limits
RATE LIMITSFinOps 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.
Blockscout Finops
FINOPSSecurity Posture 1
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.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
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.
Recommended x-agentic-access execution contracts for AI agents.

This is an independent, third-party profile of Blockscout, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
