Fireworks AI
Fireworks AI is a production-grade inference platform for open-source and proprietary generative models. The Fireworks API hosts Llama, DeepSeek, Qwen, Mixtral, Stable Diffusion, and other models with serverless pay-per-token, on-demand dedicated GPU, and batch deployment options, plus managed fine-tuning.
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 Fireworks AI the way a machine reads it — 24 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 — Fireworks AI scores 49.3/100 (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 Fireworks AI
Each block below is one kind of artifact we hold for Fireworks AI. 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.
Fireworks AI anthropic-messages.openapi_other API
The anthropic-messages.openapi_other API from Fireworks AI — 1 operation(s) for anthropic-messages.openapi_other.
Fireworks AI Chat API
The Chat API from Fireworks AI — 1 operation(s) for chat.
Fireworks AI Completions API
The Completions API from Fireworks AI — 1 operation(s) for completions.
Fireworks AI Gateway API
The Gateway API from Fireworks AI — 126 operation(s) for gateway.
Fireworks AI gateway-extra.openapi_Gateway API
The gateway-extra.openapi_Gateway API from Fireworks AI — 1 operation(s) for gateway-extra.openapi_gateway.
Fireworks AI gateway.openapi_Gateway API
The gateway.openapi_Gateway API from Fireworks AI — 126 operation(s) for gateway.openapi_gateway.
Fireworks AI Messages API
The Messages API from Fireworks AI — 1 operation(s) for messages.
Fireworks AI Responses API
The Responses API from Fireworks AI — 2 operation(s) for responses.
Fireworks AI responses.openapi_other API

OPEN COLLECTIONGraphQL 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.
Fireworks AI GraphQL Schema
This directory contains a conceptual GraphQL schema for the Fireworks AI fast inference platform. The schema is derived from the public Fireworks AI REST API surface documented ...
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.
Cost, billing, and metering signals for API financial operations.

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.
AsyncAPI definitions for this provider's event-driven and streaming APIs.
Fireworks AI Streaming Inference API
AsyncAPI description of the Fireworks AI streaming inference surface. Fireworks streams generation deltas over HTTP using Server-Sent Events (SSE) on a single `text/event-stream...
ASYNCAPISpectral 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.
Fireworks AI API Rules
SPECTRALSecurity 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.
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.
