Beautiful Soup
Beautiful Soup is a Python library for pulling data out of HTML and XML files, widely used for web scraping and screen scraping tasks. It provides a parse tree API with simple methods for navigating, searching, and modifying parsed HTML/XML documents. Beautiful Soup automatically handles encoding, supports multiple parsers (html.parser, lxml, html5lib), and integrates with CSS selectors via the Soup Sieve library. Current stable version is 4.14.3.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Beautiful Soup the way a machine reads it — 23 machine-readable artifacts across 1 API, 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 — Beautiful Soup scores 25.8/100 (emerging), with a separate agent-readiness read of 7/100 (human only). 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 Beautiful Soup
Each block below is one kind of artifact we hold for Beautiful Soup. 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 1
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.

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.

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.

Notable capabilities this provider offers.
Multi-Parser Support
Supports html.parser (built-in), lxml (fast), and html5lib (browser-like) parsers for flexible HTML/XML parsing.
CSS Selector Support
Full CSS4 selector support via the Soup Sieve library for familiar CSS-based element selection.
Tree Navigation API
Rich API for navigating the parse tree upward, downward, and sideways including find(), find_all(), parents, children, and siblings.
Automatic Encoding Detection
Automatically detects and handles document encoding using Unicode, Dammit, ensuring correct text extraction.
Tree Modification
Full tree modification support including append, insert, extract, decompose, replace_with, wrap, and unwrap operations.
Output Formatting
Multiple output formatters including prettify(), get_text(), and custom formatters for controlled serialization.
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.
