1inch
1inch is a leading DeFi aggregator providing best-execution swaps across decentralized exchanges, an intent-based Fusion order flow, cross-chain Fusion+ swaps, limit orders, and rich market data. The 1inch Developer Portal (business.1inch.com/portal) exposes 13+ REST APIs covering Swap, Orderbook, Spot Price, Token, Token Details, Charts, Balance, Portfolio, Transaction Gateway, History, Traces, Gas Price, Web3 RPC, NFT, and Domains across 14+ EVM and non-EVM chains, distributed under a single API key.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles 1inch the way a machine reads it — 21 machine-readable artifacts across 15 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 — 1inch scores 24.6/100 (emerging), with a separate agent-readiness read of 7/100 (human only). 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 1inch
Each block below is one kind of artifact we hold for 1inch. 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 15
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.
1inch Swap API
Returns optimal swap routes and ready-to-sign transaction calldata across aggregated DEX liquidity. Supports Classic Swap, intent-based Fusion, and cross-chain Fusion+ flows.
1inch Orderbook API
Limit Order Protocol orderbook — create, query, fill, and cancel signed limit orders across supported EVM chains.
1inch Spot Price API
Real-time USD and reference spot prices for tokens across supported networks, sourced from on-chain liquidity.
1inch Token API
Token metadata, lists, search, and verification across all 1inch-supported networks.
1inch Token Details API
Enriched token details including market metrics, price history, and trading stats for individual tokens.
1inch Charts API
Historical OHLCV chart data for tokens and trading pairs across supported networks.
1inch Balance API
Token balance lookups and allowance checks for any wallet across supported chains, returning balances in a unified JSON schema.
1inch Portfolio API
Cross-chain portfolio aggregation — wallet positions, protocol exposures, profit and loss, fees, and value over time.
1inch Transaction Gateway API
Submission gateway that broadcasts signed transactions and tracks status across supported EVM chains.
1inch History API
Unified wallet transaction history across all supported chains, decoded into protocol-aware events (swaps, transfers, approvals, liquidity actions).
1inch Traces API
Detailed transaction trace data for debugging and analytics across supported EVM chains.
1inch Gas Price API
Current gas-price recommendations (low / medium / high / instant) for supported EVM chains, accounting for EIP-1559 base and priority fees.
1inch Web3 RPC API
Hosted JSON-RPC endpoints for 14+ EVM and non-EVM networks, exposed through the 1inch API key for unified rate limiting and access control.
1inch NFT API
Wallet NFT holdings, collection metadata, and floor prices across supported chains.
1inch Domains API
Reverse and forward resolution for Web3 naming systems (ENS, Unstoppable Domains, and other supported registries).

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.
1inch GraphQL (The Graph Subgraphs)
1inch exposes on-chain DeFi data through multiple subgraphs deployed on The Graph protocol. These GraphQL APIs index Ethereum mainnet events from 1inch's Mooniswap AMM, Limit Or...
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.

PLANSRate 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.

FINOPSSecurity Posture 2
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.
