Waxell

Waxell is an AI agent governance and observability platform that provides runtime policy enforcement, auto-instrumented LLM telemetry, MCP governance, cost management, and durable workflow execution for agents built in any Python framework or third-party agentic tool (Claude Code, Cursor, LangChain, CrewAI, OpenAI Agents SDK, and 200+ more).

agent ready

Solid contracts, transparent operations, and an easy start — typically complete on four or five facets with one clear soft spot.

Kin Score

API Evangelist profiles Waxell the way a machine reads it — 58 machine-readable artifacts across 6 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 — Waxell scores 66.4/100 (strong), with a separate agent-readiness read of 55/100 (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 Waxell

Each block below is one kind of artifact we hold for Waxell. 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 6

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.

Open Collections 1

Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.

Open, tool-agnostic API collections (OpenAPI-derived and Bruno).

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.

Features 10

Notable capabilities this provider offers.

Auto-Instrumentation

Two-line setup auto-instruments 200+ libraries (OpenAI, Anthropic, LangChain, LlamaIndex, CrewAI, LiteLLM, etc.) without code changes.

Runtime Policy Enforcement

26 policy categories (cost, kill switch, PII, compliance, scope, safety) returning seven decisions (allow, warn, redact, throttle, block, skip, retry).

MCP Governance

Auto-instrumentor, server middleware, and governance proxy for Model Context Protocol traffic with PII scanning and rug-pull detection.

Cost Management

Built-in model pricing for 20+ models, tenant overrides via REST, budget enforcement that warns/throttles/blocks at thresholds.

Prompt Management

Versioned managed prompts retrievable by name and label (e.g. production, staging) directly from the SDK.

Workflow Envelope

Durable execution boundary with checkpoint and resume; Redis-backed in production, in-memory for development.

Human-in-the-Loop Approvals

Custom handlers route policy blocks to Slack, webhooks, or terminal prompts for human review.

Audit Trail

Immutable, timestamped record of all agent actions, decisions, and governance events.

Developer MCP

Hosted SSE MCP server (dev-mcp.waxell.dev/sse) with 15 live tools and 8 docs resources for coding agents.

Field-Level Encryption

PII fields encrypted at the application layer with AES-256-GCM and AWS KMS (FIPS 140-2 Level 3) before database storage.

Semantic Vocabularies 1

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.

JSON Schema 4

Standalone JSON Schema definitions describe the data models behind the API. We profile them so the shapes are validatable on their own — useful long after a single request is forgotten.

Examples 4

Real request and response payloads are what turn a spec from abstract into obvious — and they're one of the twelve things an agent needs to call an API correctly on the first try.

Example request and response payloads for these APIs.

Security 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.

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.
