Tezos
Tezos is a self-amending blockchain platform that uses on-chain governance to upgrade its protocol without hard forks. The primary developer API surface is provided by TzKT, an open-source Tezos blockchain indexer built and maintained by the Baking Bad team. TzKT exposes a comprehensive REST API (https://api.tzkt.io) covering 100+ endpoints for querying blocks, accounts, operations, delegations, smart contracts, big maps, tokens (FA1.2/FA2/NFTs), staking data, baking rights, governance periods, and protocol metadata on the Tezos mainnet. The API supports deep filtering, deep selection, deep sorting, CSV exports, and historical data queries at specific block heights. A WebSocket API (SignalR) provides real-time subscription streams for new blocks and operations. The public TzKT API is freely available with no API key required; rate limits apply per IP via standard RateLimit headers and HTTP 429 responses. TzKT Pro is available for teams requiring elevated quotas and dedicated support. The indexer is MIT-licensed and can also be self-hosted against a Tezos node.
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 Tezos the way a machine reads it — 260 machine-readable artifacts across 34 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 — Tezos scores 49.9/100 (developing), with a separate agent-readiness read of 39/100 (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.

How we profile Tezos
Each block below is one kind of artifact we hold for Tezos. 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 34
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.

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.

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.

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.

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.

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.
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.
