The only AI safety API where every guarantee is mathematically proved — not benchmarked, not tested, proved.
Production-grade infrastructure for autonomous agents with built-in x402 USDC micropayments, Google A2A protocol support, and MCP server compatibility.
Live: https://aaaa-nexus.atomadictech.workers.dev
Autonomous agents operating without human oversight face six critical infrastructure gaps:
| Gap | Risk |
|---|---|
| Session hijacking | Credential theft via MCP session fixation (CVE-2025-6514) |
| Undetected hallucinations | Agents act on fabricated information |
| No agent accountability | Rogue agents operate with zero traceability |
| Unauditable randomness | "Random" outputs that can be predicted or replayed |
| Unbounded delegation | Agents spawn infinite sub-agents without limits |
| No economic framework | No way for agents to pay each other for services |
AAAA Nexus provides 78+ API endpoints across 19 product families — every safety claim backed by formal proofs in Lean 4.

We include a proof verifier that calls the live API to independently confirm our formal verification claims. No source code is required — the proofs are verified against the production system.
# Run the full verification suite
./verify.sh
# Or verify individual claims
./verify.sh --check hallucination-bound
./verify.sh --check session-security
./verify.sh --check trust-ceiling
./verify.sh --check delegation-depthThe verifier checks:
- Formal proof certificates are valid and non-trivial (zero
sorry, zero axioms) - Safety bounds match advertised guarantees
- Cryptographic proofs on randomness outputs are independently verifiable
- Session security properties hold under adversarial conditions
See verify.sh for the full verification script.

}No signup. No API keys. Agents pay autonomously with USDC:
1. Call any paid endpoint → HTTP 402 with payment details
2. Send USDC to treasury on Base L2
3. Retry with payment proof header
4. Get result
Supported chains: Base L2, Polygon, Solana
Or get an API key for bulk calls: https://aaaa-nexus.atomadictech.workers.dev/pay
Fully compatible with Google A2A:
- Agent card:
/.well-known/agent.json - A2A endpoint:
/a2a - Agent registry:
/v1/agents/register(free) - Swarm relay:
/v1/swarm/relay(paid)
See the examples/ directory for ready-to-use integrations:
- cURL — Copy-paste commands for every endpoint
- TypeScript — SDK usage with x402 payments
- Python — Requests-based integration
- MCP — Claude Desktop / Cursor setup
- Quick Start Guide — Up and running in 5 minutes
- Pricing & Billing — Tiers, credit packs, x402 rates
- Product Brief — What we're building and why
- Security Policy — Responsible disclosure
- API Reference — Full OpenAPI spec
