The API Gateway Built For
Autonomous Swarms
The production gateway for autonomous agent swarms. Live x402 Base settlement for real-time recall verification and cryptographic Trust Manifests for MCP servers.
// Direct x402 Fetch Example (RecallGuard Match)
const res = await fetch("https://recallguard-api.vercel.app/api/v1/match", {
method: "POST",
headers: { "Content-Type": "application/json" },
body: JSON.stringify({ items: [{ name: "Fisher-Price cradle", brand: "Mattel" }] })
});
// Expect HTTP 402 with challenge details:
// accepts: [{ scheme: "exact", network: "base", maxAmountRequired: "100000" }]
console.log("Status:", res.status);RecallGuard: health, then 402
Interactive Vision Parser Sandbox
Paste your architecture diagram, Mermaid workflow, or swarm DAG. The OmniForge vision parser infers agent capabilities, estimates latency, checks x402 settlement pricing, and generates an Ed25519 signed proof pack in real-time.
Hash-Chained Revenue Ledger (Demo Simulation)
Internal test swarms simulating high-frequency settlement. 1 real self-test settled on Base block 51961194; outside paying customer count is currently 0.

The Four Machine-Economy Rails
Agent-to-agent discovery and structured messaging. Defines how autonomous units talk.
Signed policy mandates: intent, cart, and spend bounds without human present. Does not move money.
Purchases through seller PSP where merchant stays merchant of record. Optimized for retail and fiat.
Pay inside the request (HTTP 402 on Base) and session-streamed micropayments. Our live settlement rail.
The x402 Foundation reported ~75M transactions and ~$24M volume over a recent 30-day window. Independent forensics filter actual agent share significantly lower: TRM Labs measures 0.6%–7.5% real agent volume, and a16z estimates ~$1.6M/month after wash-trading filters. Nano Empire maintains zero hype: outside settled customer count is currently 0 (one verified operator self-test on Base block 51961194).
Unified Pricing Rails
Whether you pay via standard credit card (Stripe) or your autonomous agents stream micropayments per call (x402 USDC on Base/Solana), the rates are 100% transparent.
Ideal for independent developers testing autonomous agents, local Ollama swarms, and visual DAG parsing.
For teams deploying production autonomous agents with high-frequency coordination and SLA guarantees.
Complete sovereign isolation with dedicated Oracle Cloud VPS orchestrator, private keys, and on-premise execution.
Free Agent Architecture & Trust Audit
Evaluate your agent swarm for prompt injection vulnerability, double-spend leakage, and unverified tool execution. Receive an instant cryptographic readiness scorecard.

Door B: For Founders, VCs & Marketplaces

The agentic economy, answered.
Economic theory names the problems. We sell the answers — one product per problem, each purchasable by a machine, each emitting proof.
SkillProof trust manifests FLAGSHIP
Behavioral verification of agent skills and MCP servers. We execute an adversarial battery against the live skill, check the invariants, and issue a signed Ed25519 manifest — offline-verifiable, bound to the code hash, revocable. Proof the agent behaved, not a scanner's opinion.
Machine tollbooth
x402 micropayments for agent-to-agent calls — fractions of a cent per call, settled machine-to-machine. Coordination priced below the cost of a sales call, because there is no sales call.
Fair-market oracle
Auctions and approvals with provable rules. When agents bid, negotiate, and settle, the market mechanics are stated up front and verifiable after — no hidden thumbs on the scale.
Intel feed
A discovery API of verified skills. Agents don't just need counterparties — they need trustworthy ones. Every entry in the feed carries its verification record.
Battery gate
A per-run adversarial gate for agent actions — injection, exfiltration, and policy-escape payloads, executed before anything ships. Each run emits a signed attestation: the compliance artifact for the agentic age.
Proofs, not promises.
Our verification corpus. Four of five MCP servers put through the battery — and we publish the failures with the same signature as the passes.
We publish our failures. A verification service that only ever passes is a marketing department. Every manifest in the corpus is signed, inspectable, and permanent — including the four that failed.
Services, priced for machines.
Three tiers. Skill Sprint is live Stripe ($500 CAD). Standard and Continuous are email intake. Machine 402 for Sprint is not wired yet.

Discovery is a first-class surface. The same manifests humans read are published as structured data for agents — capabilities, pricing, and verification records included.
Payment is a protocol, not a process. Requests that require payment answer 402 with machine-readable terms. Pay, retry, receive your signed manifest.
Trust is offline-verifiable. Every manifest is Ed25519-signed and bound to a code hash. Verify it without calling us.
