Bitquery

Bitquery is a blockchain data platform that exposes a single unified GraphQL schema across 40+ networks (Ethereum, Solana, BSC, Base, Polygon, Arbitrum, Optimism, Tron, and more) through multiple delivery modes - GraphQL over HTTP, GraphQL subscriptions over WebSocket, Kafka protobuf streams, gRPC (Solana CoreCast), an MCP server backed by ClickHouse, and parquet cloud datasets. Core data products cover token prices and OHLCV, DEX trades, transfers and wallet flows, contract calls and traces, events, NFTs and metadata, balances and holders, and mempool / pending transactions.

human only

Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.

Kin Score

API Evangelist profiles Bitquery the way a machine reads it — 17 machine-readable artifacts across 10 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 — Bitquery scores 33.3/100 (thin), with a separate agent-readiness read of 13/100 (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 Bitquery

Each block below is one kind of artifact we hold for Bitquery. 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 10

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.

Bitquery GraphQL API (V2)

Unified GraphQL endpoint for querying onchain data across 40+ supported blockchains - blocks, transactions, transfers, DEX trades, balances, holders, NFTs, prices, events, trace...

Bitquery GraphQL API (V1)

Legacy GraphQL endpoint covering Bitquery's V1 schema - kept for backward compatibility while customers migrate to V2.

Bitquery Streaming Subscriptions

GraphQL subscriptions over WebSocket for real-time blockchain data - live DEX trades, transfers, pending transactions, contract events. Same V2 schema as the HTTP endpoint, deli...

Bitquery Kafka Streams

Protobuf-encoded streams of decoded blockchain data delivered via managed Kafka topics. Designed for scale-out consumption by indexers, analytics pipelines, and warehouses that ...

Bitquery Solana CoreCast (gRPC)

gRPC streaming API for Solana that delivers decoded block, transaction, and instruction data with sub-second latency. Targeted at Solana-native apps, MEV searchers, and high-thr...

Bitquery MCP Server

Model Context Protocol server backed by ClickHouse that lets AI agents query Bitquery's onchain dataset using natural language and structured tool calls.

Bitquery Cloud Datasets

Parquet-format cloud datasets containing Bitquery's decoded onchain data for direct load into data warehouses (Snowflake, BigQuery, Redshift, Databricks).

Bitquery IDE

In-browser GraphQL IDE for authoring, testing, and saving Bitquery queries against the V1 and V2 schemas. Used by developers to prototype before wiring queries into apps.

Bitquery Explorer

Multi-chain block explorer surfacing transactions, addresses, tokens, and DEX activity searchable across all chains Bitquery indexes.

DEXrabbit

Real-time DEX analytics product built on Bitquery's data - tracks trades, liquidity, volumes, and trending tokens across DEXes on multiple chains.

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.

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.

Event 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.

AsyncAPI definitions for this provider's event-driven and streaming APIs.

Spectral Rules 1

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.

Security 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.
