Gist
Gist is an AI brand-visibility, answer-engine and content-monetization platform built by ProRata (founded 2024) that helps publishers and advertisers stay visible, measurable and monetizable inside generative AI experiences. It ships three products: Gist GEO (generative engine optimization for consistent organic visibility in AI answers), Gist Ads (paid brand amplification placed directly in AI search surfaces, with native iOS and Android ad SDKs and a publisher ad tag), and Gist Answers (an embeddable, publisher-backed AI answer engine for on-site engagement and monetization). Behind those products sits a real developer surface documented at the Gist Developer Hub: the Prorata API Service (chat, streaming completions, citations, per-source attribution, threads, recommended and related questions, publisher management and document summarization) at api.gist.ai, the Gist Content API for publisher article ingestion, the Gist Content Network crawler and CMS/RSS ingestion paths, and the gist-chat-widget web component distributed from cdn.gist.ai. Gist positions itself as turning AI from a black box into a measurable, actionable channel for brands and content owners, with fair attribution and a 50/50 publisher revenue share as the stated basis of the model.
Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.
API Evangelist profiles Gist the way a machine reads it — 17 machine-readable artifacts across 2 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 — Gist scores 40.4/100 (developing), with a separate agent-readiness read of 29/100 (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. 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 Gist
Each block below is one kind of artifact we hold for Gist. 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 9
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.
Gist Content API
Publisher ingest API for the Gist Content Network. Lets publisher partners push articles to ProRata in real time (`POST /ingest/article`) or in bulk for archival backfill (`POST...

Advertising delivery surface for Gist Ads. Publishers load the `adtag.js` bundle from tp-at.prorata.ai and call `window.prtag.defineSlot({id, api_key, url, geo}, slotId, sizes, ...

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).
Prorata API Service
OPEN COLLECTIONPricing 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.

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.

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.
Standalone JSON Schema definitions for this provider's data models.
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.

This is an independent, third-party profile of Gist, 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.
