#@taas/sdk

The Fluent Developer Kit for Programmable Oracles.

@taas/sdk is the easiest way to build, simulate, and deploy verifiable oracle logic. It features a chainable "Fluent API" that allows you to define complex data intents in seconds.

Installation

pnpm add@taas/sdk

The Fluent Vision

TaaS moves beyond "Data-as-a-Service" to "Verdict-as-a-Service". Instead of fetching raw JSON and processing it in your smart contract, you define the logic at the source.

Example: Sports Prediction Market

"Will Mason score a winning goal?"

import { TaaS } from '@taas/sdk';

const intent = TaaS.intent('mason-winning-goal')
    .sports('football').score({ homeTeam: 'Arsenal', awayTeam: 'Chelsea' }) 
    .check('home_score > 2')     
    .sports('football').events({ homeTeam: 'Arsenal', awayTeam: 'Chelsea' }) 
    .check("events.some(e => e.player === 'Mason' && e.type === 'goal')")
    .attest(); // Returns a signed recipe for the Gateway

Features

• Fluent API: Chainable methods for data fetching and logical checks.
• Proxy-based Discovery: Automatically maps to Gateway capabilities.
• Simulation Parity: Uses @taas/core-rs (WASM) locally to ensure simulation perfectly matches production execution.
• verifiable Proofs: All results returned by the Gateway include cryptographic signatures verify-able on-chain.

3. TruthGatewayClient

A low-level gRPC/HTTP client for direct interaction with TaaS Gateways.

Sports Dictionary

The TaaS Gateway includes a high-fidelity sports dictionary with multi-source consensus. The system supports natural parameter resolution (GIM), removing the requirement for provider-specific identifiers.

Anonymous Data Fetching (GIM)

Fetch match or team data via name-based resolution. The Gateway translates these into provider IDs automatically.

// Fetch via team names (Internal resolution)
const score = await TaaS.sports('football').score({ 
    homeTeam: 'Arsenal', 
    awayTeam: 'Liverpool' 
});

// Fetch team details via name lookup
const info = await TaaS.sports('team').detail({ teamName: 'Chelsea' });
