public.zapper.xyz

Zapper's public API host serves agents that need structured, aggregated EVM portfolio and market data without building direct RPC or indexer infrastructure. It covers fungible token pricing, NFT collection and token metadata, wallet-level portfolio summaries across chains, and social identity lookups tied to 0x addresses. It is distinct from raw blockchain RPC hosts in that it returns pre-aggregated USD valuations, social graph data, and NFT floor prices rather than raw on-chain state.

Capabilities

Token Pricing

Provides current and historical price data for EVM fungible tokens by contract address and chain, including market cap, volume, and price change metrics.

fetch-token-pricefetch-historical-token-price

NFT Data

Covers the full NFT data surface: collection-level stats (floor price, market cap, holders, recent events) and individual token metadata (traits, media, estimated value, holder info).

fetch-nft-collection-metadatafetch-nft-token-metadata

Wallet Portfolio

Returns aggregated portfolio data for one or more EVM wallets, including cross-chain USD totals broken down by tokens, DeFi apps, and NFTs, as well as per-token NFT holdings with estimated valuations.

fetch-portfolio-totalsfetch-nft-balances

Social Identity Resolution

Resolves a 0x wallet address to its associated on-chain social identities including ENS, Farcaster, Lens, and Basenames.

Workflows

NFT Portfolio Valuation with Collection Context

Use when an agent needs to enumerate a wallet's NFT holdings and enrich each collection with floor price, market cap, and holder statistics beyond what the balance endpoint returns.

1
fetch-nft-balancesRetrieve all NFT tokens held by the target wallet(s), including per-token estimated USD values and collection addresses.
2
fetch-nft-collection-metadataFor each distinct collection address returned, fetch floor price, market cap, holder count, and recent events to provide richer context.

Historical P&L Snapshot

Use when an agent needs to calculate the USD value of a wallet's token holdings at a specific past date, such as for tax reporting or period-over-period performance analysis.

1
fetch-portfolio-totalsRetrieve the current cross-chain portfolio composition to identify which tokens and networks the wallet holds.
2
fetch-historical-token-priceFor each token of interest, fetch its price at the target historical timestamp to compute point-in-time valuations.

Wallet Identity and Portfolio Lookup

Use when an agent needs to display a human-readable identity alongside a wallet's portfolio summary, such as in a user-facing dashboard or social context.

1
resolve-wallet-social-identityResolve the 0x address to ENS, Farcaster, Lens, or Basename for display purposes.
2
fetch-portfolio-totalsFetch the wallet's cross-chain USD portfolio totals to accompany the resolved identity.

NFT Token Deep Dive

Use when an agent needs both collection-level context and individual token details for a specific NFT, such as comparing a token's estimated value against the collection floor.

1
fetch-nft-collection-metadataFetch collection floor price, market cap, and holder stats to establish the collection baseline.
2
fetch-nft-token-metadataFetch the specific token's traits, estimated value, last sale, and media to compare against the collection context.

Own public.zapper.xyz? 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.

1 route is in the 50–74 band — working, but with room to climb.
4 routes are flagged by the verifier as failing or inconclusive.

Paste this to your agent

Make my x402 API at https://public.zapper.xyz 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://public.zapper.xyz --json`. 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.
