Privacy‑Preserving Verification

InsumerAPI is a RESTful on‑chain verification service that delivers cryptographically signed boolean proofs of token and NFT ownership without exposing wallet addresses or balances. The API costs $0.04 per check and works across 31 blockchains. Merchants can use it with zero blockchain expertise, receiving only a signed “met: true/false” response. It was built by Douglas Borthwick, a 30‑year finance veteran and token‑security pioneer.

Merchant Integration and Economics

A single POST to /v1/attest evaluates up to ten conditions and returns an ECDSA‑P‑256 signature that can be verified offline. Verification costs $0.02‑$0.04 per scan, far cheaper than $1‑$5+ per click on major ad platforms. The service plugs into existing payment processors such as Stripe, Square or Clover, allowing customers to pay in dollars while token ownership unlocks discounts. Merchants receive dollars and configure discount tiers via a dashboard or API.

AI Agent Tooling and Pricing

Three SDKs—MCP, LangChain, and GPT Actions—enable autonomous AI agents to onboard merchants, generate signed discount codes, and publish directory listings without human intervention. The platform includes six companion apps covering verification, POS, dashboards, token registry and browser integration. Pricing offers a free tier (10 credits, 100 daily reads), a pay‑per‑use model at $0.04 per credit, and Pro/Enterprise plans starting at $29 and $99 per month. Documentation and SDKs are publicly available for developers.
