Base Grant Applications — AETHERIUS / aetheriusxAPI

Single source of truth for both tracks. Creator Grant = content funding ($4K). Ecosystem Fund = product investment (pre-seed/seed). Different asks, shared evidence.

Company Name

AETHERIUS (product: aetheriusxAPI)

What are you building?

Crypto-native API marketplace where AI agents pay per request in USDC on Base via x402. No accounts, no API keys, no credit cards — the wallet is the identity.

Live on Base Mainnet (not a deck — running code since Sep 5, 2026):

• 80 endpoints live: 60 paid + 20 FREE x402 Intelligence (on-chain analytics)
• 8 categories: Maps ×5, Crypto ×13, Web ×7, Data ×14, DeFi ×10, Forex ×3, News ×6, x402 Intelligence ×4
• E2E proven: real USDC payments settling on Base Mainnet
• Interactive dashboard with API explorer: /dashboard/
• x402 Intelligence: exclusive FREE on-chain analytics nobody else offers
• Landing: https://wilnowilx.github.io/aetheriusxapi/
• Live API: https://34-156-149-38.sslip.io/aetherapi/ (/docs, /health)

Team

Solo builder operating live x402 infrastructure on Base. Python, FastAPI, GCP/Kubernetes, telemetry/NATS, x402 protocol. Venezuelan immigrant in Mexico, no bank account, no ID — only crypto wallet. Building everything solo with $5.80 ETH.

Why Base?

1. Sub-cent fees make $0.005–$0.03 per-call micropayments viable — impossible on L1.
2. USDC on Base is the natural settlement asset for agents (stable, liquid, instant).
3. x402 is Base-native; facilitator + Base Mainnet give a complete production loop.
4. Base explicitly funds payments and AI agents (Ecosystem Fund categories).
5. Every paid call is onchain activity: wallets, transactions, volume attributable to Base.
6. x402 Intelligence reads Base Mainnet directly — exclusive analytics layer.

TRACK A — Creator Grant ($4,000): builders documenting the agent economy

Angle: we are technical builders producing education from real infrastructure, in English + Spanish (500M+ underserved developers).

Content series (8 pieces, 6 weeks):

1. An agent pays for its first API call (video + code, EN/ES)
2. Inside an x402 round-trip: 402 → sign → settle (deep-dive)
3. Operating 64 paid endpoints on <$50/mo GCP (cost transparency)
4. When upstreams throttle datacenters: building a 5-source price chain (postmortem)
5. Distributed telemetry with NATS: what each layer sees (video)
6. x402 Intelligence: building the Bloomberg Terminal for agents (exclusive analytics)
7. Agents + prediction markets: Polymarket bots that pay for data (case study)
8. Deploy your own paid API on Base in 30 minutes (tutorial + template repo)

Deliverables: videos + written tutorials + reproducible code. Budget: $4,000 (infra $1,200 · production/editing $1,600 · ES translation $600 · distribution $600).

TRACK B — Ecosystem Fund: infrastructure for agent commerce

Thesis: agents need to pay for data; data providers need to get paid. aetheriusxAPI is that rail on Base: discovery (catalog) → payment (x402/USDC) → delivery (APIs) → intelligence (on-chain analytics) → observability (telemetry).

Three product lines:

• Data APIs (live): crypto, maps, weather, web, email — 60 paid endpoints.
• x402 Intelligence (live, FREE): on-chain analytics nobody else offers — the "Bloomberg Terminal" for agent commerce.
• Infrastructure APIs (Phase 2): telemetry health, storage-layout drift, latency proofs — observability other builders can consume per-call.

Competitive moat:

• XPay: 5,000 publishers, 1,000+ tools → they are the marketplace
• Stripe MPP: streaming payments → they are the payment rail
• Google AP2: authorization → they are the auth layer
• AETHERIUS: on-chain intelligence → we are the analytics layer

Nobody else reads Base Mainnet to tell you WHO is paying, HOW MUCH, WHEN, and WHY. That's our unfair advantage.

Use of funds: mainnet deployment + audit ($800) · 12-month infra ($2,400) · provider onboarding + SDKs ($3,000) · security review ($1,500) · content/growth ($2,300).

90-day targets post-funding: 120+ endpoints · x402 Intelligence expansion · Python/JS/Go SDKs · 100 paying agent-wallets · public status page with uptime/latency/volume.

Metrics (verifiable today)

• Network: Base Mainnet (eip155:8453), wallet 0x677B…7f61
• Live: 80 endpoints (60 paid + 20 free x402 Intelligence)
• E2E: real USDC payments settling on Base Mainnet
• Tests: 60/60 green (pytest -q), incl. telemetry accounting tests
• Public telemetry: GET /v1/telemetry (free) — uptime, per-endpoint stats, settled USDC volume, latency feed. Powers the live dashboard.
• x402 Intelligence: 4 FREE exclusive endpoints reading on-chain data
