Alchemy
Alchemy is a Web3 developer platform offering blockchain JSON-RPC, Data APIs (NFT, Token, Transfers, Portfolio, Prices, Webhooks/Notify, Simulation), Smart Wallets / Account Abstraction (Bundler, Gas Manager), and dedicated Rollup infrastructure across 50+ chains including Ethereum, Polygon, Arbitrum, Optimism, Base, and Solana.
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.
API Evangelist profiles Alchemy the way a machine reads it — 76 machine-readable artifacts across 12 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 — Alchemy scores 53.8/100 (developing), with a separate agent-readiness read of 54/100 (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 Alchemy
Each block below is one kind of artifact we hold for Alchemy. 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 12
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.
Alchemy Node API (JSON-RPC)
Multi-chain JSON-RPC over HTTPS and WebSockets covering standard eth_*, solana, and other chain methods, plus Alchemy-enhanced subscriptions (alchemy_minedTransactions, alchemy_...
Alchemy NFT API
REST endpoints for NFT ownership, metadata, floor price, sales, contract metadata, and transfers across EVM chains and Solana.
Alchemy Transfers API
REST endpoints for paginated address-level transfer history (external, internal, ERC-20, ERC-721, ERC-1155).
Alchemy Portfolio API
REST endpoints aggregating multi-chain wallet balances, NFTs, and tokens in a single call.
Alchemy Prices API
REST endpoints for token spot and historical pricing.
Alchemy Webhooks (Notify)
REST API for managing webhook subscriptions (mined / dropped transactions, address activity, NFT activity, custom).
Alchemy Bundler API (ERC-4337)
JSON-RPC bundler endpoints for ERC-4337 user operations (eth_sendUserOperation, eth_estimateUserOperationGas, alchemy_*).
Alchemy Simulation API
REST/JSON-RPC API for simulating transactions and asset changes before broadcasting.
Alchemy Paymaster API
Sponsor user operations via ERC-4337 paymaster endpoints.
Alchemy Policies API
Create and manage gas sponsorship policies.
Alchemy Token Balances API
Retrieve ERC-20 token balances for wallet addresses.
Alchemy Token Metadata API
Retrieve metadata for ERC-20 tokens.

Open Collections 3
Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.

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.

GRAPHQLPricing 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.

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.

FINOPSEvent Specifications 1
Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.

ASYNCAPISemantic Vocabularies 3
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.

Governance rulesets we run against this provider's specs — the automated checks behind parts of the score. Profiling them makes the quality bar explicit and re-runnable, not a matter of opinion.
JSON Schema 15
Standalone JSON Schema definitions describe the data models behind the API. We profile them so the shapes are validatable on their own — useful long after a single request is forgotten.

JSON Structure captures the data shapes in a form built for tooling — a complement to JSON Schema that keeps the model machine-legible.

Examples 15
Real request and response payloads are what turn a spec from abstract into obvious — and they're one of the twelve things an agent needs to call an API correctly on the first try.

Security Posture 4
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.
