AWS Lambda
AWS Lambda is a serverless, event-driven compute service that lets you run code for virtually any type of application or backend service without provisioning or managing servers. Lambda runs your code on high-availability compute infrastructure and performs all of the administration of the compute resources, including server and operating system maintenance, capacity provisioning and automatic scaling, and logging.
Solid contracts, transparent operations, and an easy start — typically complete on four or five facets with one clear soft spot.
API Evangelist profiles AWS Lambda the way a machine reads it — 167 machine-readable artifacts across 12 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 — AWS Lambda scores 65.6/100 (strong), with a separate agent-readiness read of 80/100 (agent native). 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 AWS Lambda
Each block below is one kind of artifact we hold for AWS Lambda. 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 12
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.

OPEN COLLECTIONArazzo Workflows 13
Real integrations are rarely a single call. Arazzo describes the multi-step sequences — auth, then create, then confirm — so both a human and an agent can follow the choreography, not just the endpoints.
Multi-step API workflows described with the Arazzo specification.
AWS Lambda Release a Version Behind an Alias
Publish a version, then either move an existing alias onto it or create the alias if this is the first release.
ARAZZOAWS Lambda Shift Canary Traffic Across Two Versions
Read an alias, split its invocations between the current version and a canary version by weight, and read the routing back to confirm it took.
ARAZZOAWS Lambda Deploy a Function and Verify It Runs
Create a Lambda function from an S3 deployment package, wait for it to become Active, then invoke it once to prove it runs.
ARAZZOAWS Lambda Wire an Event Source to a Function
Confirm the target function exists, create an event source mapping onto a queue or stream, and poll until Lambda actually starts polling it.
ARAZZOAWS Lambda Audit a Function's Versions, Aliases, and Event Sources
Walk the account's functions, then drill into one to inventory its configuration, published versions, aliases, and attached event sources.
ARAZZOAWS Lambda Tear a Function Down in Dependency Order
Detach the event sources and the public URL that outlive a function, then delete the function and all its versions and aliases.
ARAZZOAWS Lambda Expose a Function Over an HTTPS Function URL
Confirm a function is Active, give it a dedicated HTTPS endpoint with an explicit auth type and CORS policy, and read the URL back.
ARAZZOAWS Lambda Find a Compatible Layer Version to Attach
Filter the account's layers by runtime and architecture, list the versions of a chosen layer, and resolve one to the exact ARN a function needs.
ARAZZOAWS Lambda Warm a Release with Provisioned Concurrency
Publish a version, point an alias at it, allocate provisioned concurrency to that alias, and wait until the environments are actually READY.
ARAZZOAWS Lambda Publish a Layer Version and Attach It to a Function
Publish a shared dependency layer from S3, verify the version, attach it to a function, and wait for the configuration update to settle.
ARAZZOAWS Lambda Cap a Function with Reserved Concurrency
Read a function's current concurrency reservation, set a ceiling on its simultaneous executions, and confirm the value Lambda stored.
ARAZZOAWS Lambda Tag a Function for Cost Allocation
Resolve a function name to its ARN, apply cost-allocation and ownership tags, and read the tags back to confirm the merge.
ARAZZOAWS Lambda Ship New Code and Cut an Immutable Version
Upload new function code, wait for the update to settle, smoke-test $LATEST, and publish an immutable version guarded by the code hash.

Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

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.

Security Posture 4
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.

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.
