Gleeful AI
Gleeful AI publishes Visibility, an AI-visibility and answer-engine-optimization audit API: it scores how visible and understandable a website is to AI assistants and agents, audits AI crawler access (GPTBot, ClaudeBot and others), generates a production-ready llms.txt and schema.org markup, checks brand citation across assistants, and runs competitor gap analysis. The access model is the notable part — there are no API keys. Every priced endpoint answers an unauthenticated request with HTTP 402 and an x402 v2 challenge in a Payment-Required header, settled in USDC on Base at prices from $0.06 to $0.55 a call, published machine-readably at /api/pricing alongside /api/capabilities and /api/catalog. Discovery, pricing and two preview endpoints are free. It is an agent-native API in both directions: built to be paid for and called by an agent, and built to measure whether agents can read you.
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 Gleeful AI the way a machine reads it — 38 machine-readable artifacts across 17 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 — Gleeful AI scores 27.5/100 (emerging), with a separate agent-readiness read of 32/100 (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.
Why this profile is thin
gleefulai.com was moved to the GoDaddy/Afternic aftermarket on 2026-08-07 and is now a domain listed for sale — the API host visibility.gleefulai.com fails the TLS handshake for its own hostname, every /api/* path 404s from the parking origin, and the wildcard even serves a generated /llms.txt whose text advertises the domain for sale, so the entire surface captured live on 2026-08-03 is gone.
This is an honest zero, not a gap in our research. Gleeful AI does not appear to expose an API, so there is nothing here for us to index and nothing for them to fix.

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 Gleeful AI
Each block below is one kind of artifact we hold for Gleeful 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 17
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.
Gleefulai Plans
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.
Gleefulai Rate Limits
RATE LIMITSSecurity 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.

This is an independent, third-party profile of Gleeful AI, 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.
