Send a wallet address and one or more conditions. InsumerAPI reads the wallet state, evaluates the conditions (a single rule or a composite of tokens, NFTs, on-chain attestations, identity), and emits a cryptographically signed yes or no. No balances exposed. No blockchain code required. One API for commerce, compliance, access control, and AI agent trust.
Every use case follows the same pipeline: read wallet state, evaluate one or more conditions, sign the result, verify independently. Condition-based access, four steps.
Read wallet state across 37 chains — tokens, NFTs, on-chain attestations
Produce signed attestations you can verify independently
Check every result yourself using our public signing key
Commerce, compliance, access control, or agent trust
Three products, one primitive. Each layer builds on the one before it. Together they form a system that doesn't just verify — it enforces continuously.
InsumerAPI reads blockchain state and returns signed booleans. The foundation: does this wallet meet these conditions, yes or no?
POST /v1/attest
SkyeProfile runs 40+ checks across multiple dimensions and returns a signed trust profile. The judgment layer: should you transact with this wallet?
POST /v1/trust
AgentTalk maintains conditions over time. Agents join by proving qualification and stay only while they still qualify. Enforcement that runs itself.
One-time verification answers "does this wallet qualify right now?" Continuous enforcement answers "does it still qualify?" — and acts on the answer automatically.
The most common application of wallet auth is condition-based commerce: merchants verify wallet state and reward token holders at checkout. Each side has a dedicated walkthrough.
Turn token holders into paying customers without touching crypto. Configure conditions, scan at checkout, apply discounts. InsumerScanner, InsumerDashboard, and Stripe / Square / Clover integration.

See the holder walkthrough →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 result is cryptographically signed. Don't trust our server—verify every response yourself using our public key 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. This also means ephemeral proofs with nothing to harvest.
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 37 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).
Agent SDKs: MCP, LangChain, OpenAI GPT, ElizaOS. Framework adapters that package the wallet auth primitive into host-shaped surfaces: WDK protocol module (Tether’s Wallet Development Kit), mppx condition-gate (Machine Payments Protocol routes).

31 EVM chains plus Solana, XRP Ledger, and Bitcoin. Tokens, NFTs, trust line assets, and on-chain identity records. One API call covers all of them.
No. The Insumer Model™ is read-only verification infrastructure. It reads blockchain state and returns signed attestations. 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.
Token balances: any ERC-20 (31 EVM chains), SPL token (Solana), XRPL trust line token, native Bitcoin, TRC-20 token (Tron), Stellar trustline asset, or Sui-native token — 37 supported chains total. NFT collections: supported on EVM, Solana, and XRPL. 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.
