Celery
Celery is an open-source distributed task queue for Python. It allows you to run tasks asynchronously in the background, enabling scalable distributed systems with support for multiple message brokers (RabbitMQ, Redis, Amazon SQS) and result backends. Celery provides a rich set of Python programming APIs for defining tasks, composing workflows, scheduling periodic work, executing on workers, and monitoring execution.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Celery the way a machine reads it — 15 machine-readable artifacts across 8 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 — Celery scores 39.0/100 (thin), with a separate agent-readiness read of 22/100 (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. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Celery
Each block below is one kind of artifact we hold for Celery. 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 8
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.
Celery Task API
Core API for defining and executing distributed tasks in Celery. Supports task decorators, retries, timeouts, rate limiting, and custom task classes.
Celery Application API
Application configuration and initialization API for Celery, used to configure brokers, result backends, serialization, routing, and task discovery.
Celery Canvas API
Canvas is Celery's workflow composition API for building complex task orchestrations using signatures, chains, groups, chords, maps, starmaps, and chunks.
Celery Beat API
Celery Beat is the scheduler for periodic tasks, supporting crontab-style schedules, interval schedules, and solar schedules. It can also be backed by a database scheduler for d...
Celery Worker API
Worker API for executing distributed tasks with configurable concurrency (prefork, gevent, eventlet, solo, threads), autoscaling, remote control, and signal handling.
Celery Result Backend API
Result backend API for storing and retrieving task results and state using backends such as Redis, RPC, database, Memcached, Cassandra, and S3.
Celery Signals API
Signals API for hooking into Celery lifecycle events including task, worker, beat, and consumer signals to build extensions and observability.
Celery Monitoring and Events API
Event streaming and monitoring API for inspecting workers, tasks, and queues. Supports the curses-based celery events monitor and third-party tools such as Flower.

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 things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.
Published pricing tiers and plan structures.
Celery Plans Pricing
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.
Celery Rate Limits
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.
Celery Finops
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.
Celery Worker Event Stream
Celery workers publish a monitoring event stream over the configured broker. This document is a faithful transcription of the published Event Reference in the Celery Monitoring ...
ASYNCAPISecurity Posture 3
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.

This is an independent, third-party profile of Celery, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
