Exa Finance
EXA Finance is a French Web3 company, founded in 2021, that builds EXA Market — a peer-to-peer NFT and multi-asset marketplace on the Algorand blockchain. Because Algorand represents both fungible tokens and NFTs under the single ASA (Algorand Standard Asset) standard, the EXA Market protocol lets users bundle up to four assets into a "basket" and trade them in a single transaction, sell NFTs for any ASA rather than only the native ALGO token, make peer-to-peer offers, and run standard sales, normal and Dutch/reverse auctions, and multi-mints. Creators set an on-chain royalty fee of up to 15% globally against their creator address, payable in ALGO, USDC, USDT and other opted-in assets. The protocol is governed by the EXA token (ASA ID 1888888888) through the EXA Community DAO, whose EXRC/EXIP proposal lifecycle is modeled on Uniswap, dYdX, Tinyman and Blur. EXA raised a $2M seed round in January 2022 with Speedinvest, Lemniscap, Big Brain Holdings, Borderless Capital, Encode Club, Meld Ventures, 11-11 DG Partners and 0x Ventures. EXA Market publishes no public HTTP/REST API: its programmable surface is on-chain Algorand smart contracts (listing, offer and auction contracts, published as TEAL approval programs), reached through standard Algorand algod and indexer node APIs and the Algorand SDKs.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles Exa Finance the way a machine reads it — 1 machine-readable artifact, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Exa Finance scores 13.1/100 (minimal), with a separate agent-readiness read of 4/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Exa Finance
Each block below is one kind of artifact we hold for Exa Finance. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
Security Posture 1
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
