Spraay Compute & Futures — OpenClaw Skill 💧

GPU compute, AI model inference, and prepaid compute futures for AI agents — paid in USDC over x402, no API keys and no accounts.

Compatible with OpenClaw, Claude Code, Cursor, GitHub Copilot, Codex, Gemini CLI, and 18+ other agents via the Vercel Skills CLI.

Install

OpenClaw / ClawHub:

Or paste this repo's URL into your OpenClaw agent and it will install the skill automatically.

What it does

Two capabilities at equal billing, both settled in USDC over x402 V2 on Base mainnet and Solana mainnet:

Compute rental (pay per call)

• GPU run — any Replicate model (image, video, LLM, audio, utility) — $0.06
• Text inference — LLM chat/completion, 11 models 3B–405B via Chutes AI (Bittensor SN64) + OpenRouter — $0.03
• Image generation — FLUX Schnell/Dev/Pro, SDXL — $0.03
• Video generation — MiniMax Video 01, Wan 2.1 (async) — $0.50
• Text-to-speech — $0.03 · Speech-to-text — Whisper Large V3, 100+ languages — $0.02
• Embeddings — for RAG and semantic search — $0.005
• Batch — up to 50 mixed jobs in one payment, 10% discount — $0.05
• Estimate / model list — free

Compute futures (prepay and draw down)

• Deposit USDC into a credit account — $0.01. Tier discounts: $10+ (5%), $50+ (10%), $200+ (15%)
• Execute jobs against the balance with no per-call x402 — only $0.001 settlement, discount applied
• Balance / history / pricing — check what's left and what you've spent
• Refund unused balance back to the depositor anytime — $0.01

Why an agent wants this

• No accounts, no API keys — a funded wallet is the only credential.
• Pay only for what you use — per-call micropayments, or prepay for a discount.
• Predictable spend — open a futures account, run a workload, refund the rest.
• Discovery-native — the gateway exposes a machine-readable catalog at /.well-known/x402.json.

Endpoints

Base URL: https://gateway.spraay.app

Full request/response schemas and model lists are in references/endpoints.md. Runnable examples — per-call and the full futures lifecycle — are in examples/quickstart.md.

Payment

x402 V2. The gateway answers protected routes with 402 Payment Required; your x402 client signs a USDC authorization (EIP-3009 on Base, SPL on Solana) and retries. Works with @x402/fetch, x402-axios, the Spraay MCP server, or any OpenClaw payment skill.
