Gigacatalyst (Giga Next Inc.) is a Y Combinator-backed enterprise AI platform that embeds an API-connected app builder directly into B2B SaaS products, so that customers, solutions engineers, and customer-success teams can describe a dashboard, report, or workflow in natural language and have it generated against the host product's own APIs, design language, permissions, and roles. Generated apps run inside the customer's environment using the signed-in user's session credentials, with granular write control and a choice of a Managed deployment (routed through the Gigacatalyst proxy for caching, rate limiting, and analytics, with AWS Bedrock zero-retention AI) or a Direct deployment where nothing routes through Gigacatalyst and the customer brings their own AI key. Gigacatalyst is primarily an API consumer rather than an API producer, but it does publish one public, unauthenticated, agent-facing operation - the self-serve registration endpoint documented at v2.gigacatalyst.com/agent.md - plus an official npm SDK and CLI, an embeddable React chat component, and an open-source browser extension.
Gigacatalyst publishes 1 API on the APIs.io network. Tagged areas include Company, Artificial Intelligence, Software-as-a-Service, Sales Enablement, and Solutions Engineering.
Gigacatalyst’s developer surface includes documentation, API reference, getting-started guide, engineering blog, signup flow, CLI, authentication, and 21 more developer resources.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/gigacatalyst: open an issue to ask a question, or submit a pull request to add artifacts.

note: A workspace can be created without contacting sales - the public, unauthenticated registration endpoint creates one
from an email address alone - but no price, tier, or quota is published anywhere and /pricing returns 404. See plans/gigacatalyst-plans-pricing.yml.

- name: Gigacatalyst Self-Serve Registration API
description: 'The one public, unauthenticated operation Gigacatalyst publishes on its own behalf. A coding agent reads the
project''s API surface, builds a JSON description of it (organization, integrations, tools with inputSchema and outputSchema,
safety levels, optional domain documents) and POSTs it to https://v2.gigacatalyst.com/api/self-serve/register, which creates
the human''s workspace and returns a single-use sign-in URL, an account password, a tool count, and a per-connection credential
checklist. The request and response contracts, the validation rules the endpoint enforces, and the auth vocabulary are
documented in full in the provider-published agent instructions at https://v2.gigacatalyst.com/agent.md. Verified live:
OPTIONS returns 204 with "allow: OPTIONS, POST"; GET returns 405.'

note: 'Contract discovery overturned the prior "API consumer, no public API" conclusion. Gigacatalyst publishes one real,
live, unauthenticated API operation - POST https://v2.gigacatalyst.com/api/self-serve/register - documented only inside
provider-published agent instructions at https://v2.gigacatalyst.com/agent.md, which are saved verbatim as agent skills.
Also found: official npm SDK + CLI (gigacatalyst 0.2.2, 2026-07-07), an Apache-2.0 browser extension, a trust center,
and a vulnerability disclosure policy at a non-standard path. Corrected a false SOC 2 certification credit written by
the mechanical trust-center probe.'
