Send a wallet address and conditions. Get an ECDSA-signed boolean or standard JWT. No balances exposed. No Web3 libraries required. One API for commerce, compliance, access control, and AI agent trust.
Every use case follows the same pipeline: read blockchain state, sign the result, verify independently, then act on it.
Check wallet conditions across 33 chains — tokens, NFTs, attestations
Produce ECDSA-signed booleans or standard JWT bearer tokens
Check signatures via JWKS endpoint or insumer-verify npm package
Commerce, compliance, access control, or agent trust
The most common application: merchants verify wallet holdings and reward token holders at checkout. Here's the step-by-step for both sides.
Go to insumermodel.com/wallet in your browser. No app download needed.
Connect MetaMask, Phantom, and Coinbase Wallet, individually or all at once. Holdings are aggregated across all connected wallets.
The system automatically scans your tokens and NFTs across all 33 supported chains.
When you're at a participating merchant, show your QR code or tap your phone for NFC verification.
Go to insumermodel.com/dashboard and sign up. Takes 2 minutes. No credit card required.
Choose up to 8 tokens and 4 NFT collections to recognize. Set discount tiers by holding amount.
Optional: Link Stripe, Square, or Clover to auto-generate discount codes. Or apply discounts manually.
ACME15 are created automatically for each tier.
Open InsumerScanner on any device. Scan the customer's QR code or tap their NFC card. Apply the displayed discount.
Tokenized real-world assets are projected to reach $13-16 trillion by 2030 (BCG/ADDX, McKinsey). That's not speculation about crypto prices. That's traditional stocks, bonds, and real estate moving onto blockchain rails.
BlackRock BUIDL alone
Wallet verification is evolving. What started with passionate crypto communities will soon include every shareholder.
Passionate communities with tribal affiliations. SHIB Army, PEPE holders, Bored Ape Yacht Club, Pudgy Penguins. Millions of holders who identify with their tokens.
Institutional players entering the space. BlackRock's BUIDL, Franklin Templeton's BENJI, Ondo Finance's USDY. Traditional assets moving onto blockchain rails.
NYSE and NASDAQ equities moving on-chain. Your Apple shares, your Tesla stock—all verifiable via API. Every shareholder becomes a potential Insumer.
Each app serves a specific purpose. Together, they create a complete wallet verification infrastructure—in-store, online, and via API.

For the technically curious: here's what happens when InsumerAPI processes a verification request.
Every attestation is signed with ECDSA P-256. Don't trust our server—verify our signatures independently via the JWKS endpoint at /.well-known/jwks.json or the insumer-verify npm package.
Pass format: "jwt" on POST /v1/attest and receive a standard ES256-signed JWT. Verifiable by Kong, Nginx, Cloudflare Access, AWS API Gateway, or any JWT library.
Your system asks "does this wallet hold ≥100 USDC?" and gets yes or no—never the actual amount. Critical for privacy, compliance, and agent trust.
We don't collect personal information. Wallet addresses are not stored. Read-only access only—we never request transaction signing or token approvals.
Token balances and NFT ownership are read directly from blockchain RPCs across 33 chains. No intermediary databases. All chains scanned in parallel.
REST API with 7 public and 19 authenticated endpoints. Flagship: POST /v1/attest (conditions), POST /v1/trust (wallet trust profile), POST /v1/trust/batch (bulk).
Native integrations for MCP, LangChain, OpenAI GPT, and ElizaOS. AI agents can verify wallet state without custom RPC logic.
Free tier: 100 requests/day, no credit card. Pro and Enterprise tiers for higher volume. See pricing or get a key instantly at developers/account.
30 EVM chains plus Solana and XRP Ledger. Tokens, NFTs, trust line assets, and EAS attestations. One API call covers all of them.
No. The Insumer Model™ is read-only verification infrastructure. It reads blockchain state and returns signed credentials. It never moves funds, processes payments, or interacts with wallets.
API responses typically return in 1–3 seconds, even when checking multiple conditions across multiple chains. For commerce, QR code scans verify in 2–3 seconds and NFC taps verify in real time.
Any ERC-20, SPL token, XRPL trust line token, native Bitcoin, or NFT collection across 33 supported blockchains. You specify the contract address and chain ID in your API call — the system verifies against live on-chain state.
Free tier: 100 daily reads and 10 verification credits, no credit card required. Pro and Enterprise tiers for higher volume, with volume discounts up to 50%. See full pricing →
The API returns true or false — whether a wallet meets a condition or not. It never exposes actual token balances, NFT inventories, or transaction history. This is privacy by design at the protocol level.
