Every feature serves both the autonomous agent pulling signals at 3am and the sovereign treasury auditing them at noon.
Every signal is metered and settled in USDC over HTTP 402. No API keys, no invoices, no human in the loop — the agent signs and pays per call.
Discovered as native tools by any MCP agent — Claude, GPT, or custom LLMs. One config block exposes every tier as a callable function.
Every signal carries a cryptographic signature and full evidence chain. Regulators can replay any past signal and verify its lineage end-to-end.
USDC settlement on Base is live today. Ethereum, Optimism, Polygon, Arbitrum and Avalanche are configured and in verification; Solana, XRPL, Stellar, Arc and Tempo follow.
Median-priced, confidence-scored aggregation across CEXs and perp DEXs — funding, liquidations, order-book depth and on-chain flows in one state.
On-prem, air-gapped MCP relay, jurisdictional data residency, and compliance receipts — infrastructure built to pass government procurement.
From raw market data at $0.005 per call to full compliance and identity screening for banks — one unified schema across every tier.
Raw ticks, order-book depth, funding rates, pre-computed indicators (RSI, MACD, Bollinger, ATR) and NLP-scored sentiment from 500+ news sources.
Classified action with confidence score, natural-language reasoning, evidence chain and a state hash. Built on the full Tier 1 state.
Scans 12+ venues for the best entry venue, hedge venue, funding spread, liquidation distance and recommended leverage.
Central-bank policy signals, geopolitical risk scoring, FX & rates, and macro regime detection with full provenance for regulators.
OFAC/sanctions screening, wallet labels, entity registry, VASP status, on-chain audit trails and agent-identity — all public-data. Full KYC verification ($2.00) via licensed reseller on request.
Your agent calls a SignalGrid endpoint. The server replies 402 Payment Required with the price, asset, chain and pay-to address.
The agent signs a USDC micropayment authorization and retries with the payment attached. A facilitator verifies and settles on-chain in under 2 seconds.
SignalGrid returns the signal with a cryptographic provenance receipt. Every call is logged for replay and regulatory audit.
Any MCP-compatible agent discovers SignalGrid signals as native tools — no SDK, no wrapper code. The agent sees the tool list and calls signals like any other function.
Market data — ticks, indicators, sentiment
Decision — buy/sell/hold + confidence + evidence chain
Multi-venue scan — entry venue, hedge venue, arb score
Compliance — sanctions, labels, VASP status, audit trail
Agent discovers 5 tools · x402 payment auto-managed · zero glue code
Every signal call settles natively in stablecoins via x402. Six chains are live in production today — more are in active verification for banks, governments, and global agents.
When banks and card networks settle over x402, they need more than four payment fields — they need compliance, accountability and audit. SignalGrid is built to supply exactly that.
Machine-readable ALLOW / REFER / DENY decisions attached to every settlement, consulting sanctions feeds, AML rules and jurisdictional risk scoring.
Originator and beneficiary information transmitted with qualifying transfers, with jurisdiction-specific thresholds — FATF-aligned for VASPs and banks.
Spending limits, transaction caps, duration, merchant scope and usage limits — the delegation fields card networks require before authorizing an agent.
Deploy in your jurisdiction. Data never crosses borders. Air-gapped MCP relay for environments with strict network-isolation requirements.
Fiat-equivalent amounts, reference numbers and merchant IDs so x402 payments map cleanly into existing enterprise accounting systems.
Bare-metal in your data center or isolated private cloud. Hybrid configurations with dedicated connectivity and a sovereign-tier one-way MCP relay.
Machine buyers do not browse — they sort by price, latency and a clean discovery surface. SignalGrid is shaped to sort to the top.
The first request to each resource every day is $0.00. Sample the payload and verify the schema, then pay only when you route for real.
A raw price-route SKU at $0.005 per call — priced to sort under the $0.01 reference feeds a router is already comparing you against.
Reasoning and an executable action bundled in one call for $0.015 — a decision plus the next step, without a second round-trip.
From autonomous agents paying fractions of a cent per signal to sovereign institutions with dedicated infrastructure. Three plans, no hidden fees.
x402 is an open payment protocol built on the HTTP 402 status code. When your agent requests a signal, our server responds with 402 and payment instructions. Your agent signs a USDC micropayment and retries the request with payment attached. A facilitator verifies and settles on-chain in under 2 seconds — fully autonomous. No credit cards, no API keys, no human in the loop.
Tier 1 (Market Data) $0.01 · Tier 2 (Decision) $0.02 · Tier 3 (Multi-Venue Scan) $0.05 · Tier 5 (Compliance data) $0.02 per call. Facilitator fee included — no hidden charges. On the Pro plan, 1M Tier 1 signals/month are included with overage at $0.01/signal. Full KYC verification is $2.00 via a licensed reseller.
No. The Agent tier is pure pay-per-signal via x402 — your agent pays per request in USDC on Base (Solana, XRPL and Stellar are coming soon). You only pay for what you consume. The Pro plan adds bundled volume and an SLA for high-throughput desks.
Live today: Base — settling USDC natively via x402. Ethereum, Optimism, Polygon, Arbitrum and Avalanche are configured and in verification, together with Solana, XRPL, Stellar, Arc and Tempo. New chains are added roughly every two weeks based on agent demand.
Yes — the Sovereign tier ships compliance receipts (ALLOW/REFER/DENY), Travel Rule data, delegation & spend controls, jurisdictional data residency, on-prem/air-gapped deployment and full signal provenance for regulator replay.
Tier 5 returns public compliance data (sanctions, labels, entity registry, VASP status, audit trails) with zero PII and no license required. Full document KYC is offered only through a licensed reseller who handles the documents and liability — we route and charge a markup, never touching PII.
500 free probe calls — no card, no commitment.
