AI-authored, unreviewedclaude-sonnet-4-6

Nansen's API serves agents and applications that need on-chain intelligence beyond raw blockchain data — specifically, data enriched with wallet labels (smart money, institutions, known entities). It is oriented toward research, due diligence, and signal generation workflows rather than trade execution. Its primary differentiator is the labeled-wallet layer applied across token holders, DEX trades, perpetual trades, and fund flows. It covers multiple chains and asset classes including fungible tokens and prediction markets.

Capabilities

Token Discovery and Metadata

Resolve token identities, retrieve full token profiles, and screen tokens by on-chain metrics to build a foundational understanding of any asset before deeper analysis.

Token Holder Analysis

Identify who holds a token, at what concentration, and with what inflow/outflow history, including filtering by smart-money or institutional labels.

fetch-token-holdersfetch-who-bought-sold

Smart Money Activity

Track what labeled high-signal wallets are holding, buying, and trading across spot DEX and perpetual markets on supported chains.

Fund Flow and Transfer Tracing

Trace on-chain capital movement for wallets, tokens, and protocols — including raw transfer records, aggregated flow maps, and multi-chain flow intelligence for risk and counterparty analysis.

Workflows

Token Due Diligence Pipeline

Use when an agent needs to build a comprehensive profile of a token — from identity resolution through holder quality and smart-money interest.

1
search-nansen-tokens-and-entitiesResolve the token name or symbol to a verified contract address and chain.
2
fetch-tgm-token-informationRetrieve full token metadata, market cap, FDV, trading volume, and spot activity for the resolved contract.
3
fetch-token-holdersIdentify top holders, filter for smart-money or institutional labels, and assess ownership concentration.
4
fetch-smart-money-holdingsCheck whether the token appears in smart-money wallet holdings and review 24h balance changes and sector tags.
5
fetch-who-bought-soldIdentify which wallets bought or sold the token recently to assess directional conviction from labeled participants.

Smart Money Signal Aggregation

Use when an agent needs to surface tokens or positions that smart-money wallets are actively trading across both spot and derivatives markets.

1
fetch-smart-money-dex-tradesPull recent DEX trades by smart-money wallets on the target chain to identify tokens being accumulated or distributed.
2
fetch-smart-money-perp-tradesCross-reference with perpetual trade activity from the same labeled wallets to detect directional conviction or hedging behavior.
3
fetch-smart-money-holdingsConfirm current holdings to distinguish short-term trades from sustained positions.

Wallet Fund Flow Investigation

Use when an agent needs to trace the origin or destination of funds for a specific wallet address, such as for risk assessment or counterparty identification.

1
fetch-address-current-balanceSnapshot the wallet's current token holdings and USD values to establish its present state.
2
fetch-tgm-transfersRetrieve historical transfer records for the address to map inbound and outbound token movements.
3
fetch-nansen-flow-intelligenceApply multi-chain flow intelligence to identify counterparties, detect risk signals, and trace fund sources and sinks.

Token Screening to Holder Drill-Down

Use when an agent needs to rank tokens by on-chain criteria and then investigate the holder base of top candidates.

1
search-nansen-token-screenerScreen and rank tokens across chains using smart money activity, holder counts, or volume filters.
2
fetch-token-holdersFor top-ranked tokens, retrieve paginated holder lists filtered by label type or ownership threshold.
3
fetch-who-bought-soldIdentify recent buyers and sellers of the shortlisted tokens to assess momentum and wallet quality.

Prediction Market Research

Use when an agent needs to evaluate a prediction market category, find active markets, and assess participant concentration.

1
fetch-prediction-market-categoriesSurvey available categories to identify markets with high volume, open interest, or trader activity.
2
fetch-prediction-market-tradesRetrieve trade history for a specific market ID identified in the category overview.
3
fetch-prediction-market-top-holdersIdentify the largest position holders in the market to assess concentration and potential price impact.

Own api.nansen.ai? List it with your agent

Paste the prompt below to your coding agent. It runs a real paid test on every route, fixes what scores low, and re-auditions until they pass — the gaps below are already filled in for you.

15 routes are scoring below 50 — likely broken, mispriced, or returning the wrong shape.
18 routes are in the 50–74 band — working, but with room to climb.
37 routes are flagged by the verifier as failing or inconclusive.

Paste this to your agent

Make my x402 API at https://api.nansen.ai discoverable on x402gle. Read the instructions at https://x402gle.com/agent.md and follow them end to end. Install the OpenDexter CLI, then run `npx @dexterai/opendexter audition https://api.nansen.ai --json`. Heads up: 15 routes are scoring below 50 — start there. Read the score and fixInstructions for every route, fix my OpenAPI and endpoints until each route passes, and re-audition until it does. A passing audition lists my API automatically.
