## EasyFunctionCall

EasyFunctionCall targets a very specific pain point in AI application development: giving language models the ability to call real APIs. Manually translating a large OpenAPI or Swagger document into function definitions is tedious, error-prone and expensive in tokens, especially when an API exposes dozens or hundreds of endpoints. The platform automates that translation, producing compact function-call parameters that AI models can consume without bloating the context window.

Because oversized schemas eat into the context budget on every request, EasyFunctionCall positions token optimisation as a core benefit. By generating leaner parameter structures, teams can fit more tools into a single model call and control inference costs as their API surface grows. The result is a faster path from an existing REST API to an AI agent or assistant that can actually take action.

The service is aimed at backend and AI engineers, integration specialists and product teams shipping autonomous workflows. It supports common model providers and works with standard specification formats, so it slots into existing documentation pipelines rather than replacing them.

**Pricing & Plans:** Freemium. A free tier is available to convert specifications and try the workflow, with paid plans for higher volumes and production use. Check the site for current limits.

- **OpenAPI and Swagger conversion:** Ingest standard OpenAPI or Swagger specifications and export function-call parameters ready for AI model tool use.
- **Token-efficient output:** Generates compact parameter definitions that reduce the context cost of exposing large API surfaces to language models.
- **Multi-model support:** Designed to work with popular model endpoints including ChatGPT/OpenAI, Claude, Gemini and Llama family models.
- **SaaS, no local setup:** A hosted web service, so teams can convert specs through the browser without maintaining parsing infrastructure.
- **Fits existing docs workflows:** Works from the API specifications development teams already maintain, avoiding duplicate schema authoring.

**Strengths:** Saves significant token budget when exposing many endpoints to a model; Removes repetitive manual function-schema authoring; Works with the OpenAPI/Swagger specs teams already have; Supports several major model providers

**Limitations:** Value depends on having a well-formed API specification to begin with; Developers still need to validate generated parameters against model-specific quirks; Hosted SaaS means API specs leave your environment unless handled carefully

## Outlier AI

Outlier AI is a work platform built around the idea that human expertise is still the fastest way to make AI models better. Professionals in fields such as software engineering, mathematics, physics, medicine and dozens of languages sign up, verify their skills, and are matched with projects where they write difficult prompts, build answer rubrics and grade model outputs. Because the work is project-based and fully remote, contributors set their own hours with no minimum commitment.

The platform reports more than 900,000 experts onboarded and over $500 million paid out to contributors across 50 countries, with a large share of participants being graduate students and PhDs. Typical accounts describe a 30 to 90 minute onboarding flow covering account creation, expertise selection, skill screening and identity verification, after which project-specific training begins.

Outlier is part of the Scale AI family of data-labeling businesses, so the projects generally feed into real model-development pipelines rather than academic exercises. Pay is competitive and quality-based, disbursed weekly, and contributors sometimes get free access to paid frontier models as part of their work. Because project availability fluctuates, income is best treated as flexible supplementary earnings rather than a guaranteed full-time salary.

**Pricing & Plans:** Free for experts to join. Outlier pays contributors for completed work rather than charging them; rates vary by project, expertise area and locale, with quality-based bonuses and weekly payouts.

- **Expert-matched project work:** After skill screening, contributors are matched to projects that fit their domain, from coding and math to linguistics and medicine.
- **Genuinely flexible schedule:** No minimum hours and fully remote work, so experts can fit tasks around study, research or a primary job.
- **Varied AI-training tasks:** Typical work includes writing hard prompts, producing grading rubrics, ranking competing answers and reviewing model reasoning.
- **Weekly, quality-based pay:** Contributors are paid for approved work each week, with rewards that scale with the quality of their output.
- **Skills that transfer:** Contributors build hands-on prompt-engineering and evaluation experience that carries into AI and data roles.

**Strengths:** Remote, project-based work with no minimum hours; Open to strong generalists as well as advanced degree holders; Weekly payouts with quality-based rewards; Builds practical prompt-engineering and evaluation experience

**Limitations:** Project availability and hours can be inconsistent; Onboarding, skill screening and identity checks take time; Rates and project access vary significantly by region and specialty
