Navigating the Shift: Moving from Mobula to Zerion API Post-Acquisition

On August 31, 2026, fomo announced its acquisition of Mobula’s technology and intellectual property, marking a pivotal moment for both companies. Key Mobula figures, including founder Sacha Marcus, CTO Sacha Delhoux, and Head of Infrastructure Cyril Conan, will join fomo's engineering team, indicating a clear intent to consolidate expertise and resources within the new organization.

Despite the acquisition, Mobula has not disclosed any immediate plans to shut down its public API, and no specific migration deadline is in place. This offers current users a flexible opportunity to strategize their migration to alternative services without the pressure of an impending cutoff.

If your on-chain data has been managed through Mobula's API, now could be an opportune time to consider transitioning to the Zerion API. This API provides comprehensive access to wallet balances, DeFi positions, transaction histories, and portfolio management across multiple EVM chains and Solana, all presented under a unified structure. Below, we’ll delve into what the Zerion API can offer and how to map your existing setups to their endpoints.

Zerion API Overview

The Zerion API is tailored for enterprises needing detailed on-chain wallet data. Its primary endpoints are organized around wallet addresses and come pre-configured to support various chains, enabling quick responses formatted in your designated currency for immediate usability.

• Token Balances and DeFi Positions: /v1/wallets/{address}/positions/ — This endpoint conveniently merges the retrieval of standard token balances and detailed DeFi positions in one call. Filters are available for specific types.
• Portfolio Aggregation: /v1/wallets/{address}/portfolio — Users can access total values, changes over 24 hours, and breakdowns by chain and position type.
• Transaction History: /v1/wallets/{address}/transactions/ — This retrieves a detailed list of transactions, along with transfers, fees, and dApp identifications.
• Portfolio Chart: /v1/wallets/{address}/charts/{period} — Provides historical insights into net worth over specified timeframes.
• Wallet Performance Analysis: /v1/wallets/{address}/pnl — This endpoint outlines both realized and unrealized gains, investment totals, and expenses.
• Fungible Assets: /v1/fungibles/ — Access a full listing of assets in Zerion's universe, complete with relevant metadata.
• Transaction Webhooks: /v1/tx-subscriptions/ — Notifies your service about transaction happenings in real time for tracked wallets.
• NFT Data: /v1/wallets/{address}/nft-positions/ — Retrieves NFTs associated with a wallet, with an endpoint that can organize them by their respective collections.

What's particularly interesting is the API's compatibility with both EVM and Solana addresses. Users can forgo the necessity of chain filters, pulling data for all supported chains in a single request or fine-tuning results based on specific chains.

Translating Mobula to Zerion Endpoints

When transitioning from Mobula to the Zerion API, the good news is that many of Mobula's wallet endpoints have direct equivalents in Zerion. Moreover, multiple calls previously needed within Mobula can now be streamlined to singular requests with Zerion, enhancing efficiency.

GET /1/wallet/portfolio → GET /v1/wallets/{address}/portfolio + GET /v1/wallets/{address}/positions/

GET /2/wallet/holdings → GET /v1/wallets/{address}/positions/?filter[positions]=only_simple

GET /2/wallet/defi-positions → GET /v1/wallets/{address}/positions/?filter[positions]=only_complex

GET /2/wallet/activity → GET /v1/wallets/{address}/transactions/

GET /1/wallet/nfts → GET /v1/wallets/{address}/nft-positions/

GET /1/wallet/history → GET /v1/wallets/{address}/charts/{period}

GET /2/wallet/positions → GET /v1/wallets/{address}/pnl

GET /1/all → GET /v1/fungibles/

GET /1/blockchains → GET /v1/chains/

POST /1/webhook → POST /v1/tx-subscriptions/

There are significant advantages to migrating:

• Reduced API calls: For users who currently make separate requests for holdings and DeFi positions, Zerion simplifies this into one comprehensive call.
• No multi-chain charges: Unlike Mobula, which incurs costs for each chain queried, Zerion allows one query across all chains without additional fees.

Expanding Horizons with Zerion

In terms of DeFi interaction, Zerion surpasses Mobula's offerings by eliminating protocol restrictions while broadening covered positions. Each position is clearly categorized, simplifying your workflow without requiring distinct parsing logic for various DeFi contracts.

Another appealing feature is the uniform schema that Zerion employs across its endpoints for different chain families. This consistency means that the code utilized for data transformation and display can be utilized without adaptations across various chains.

Furthermore, Zerion API is tried and true — it's the backbone of the Zerion Wallet and is also integrated by leading platforms like OpenSea and Kraken, affirming its reliability and widespread acceptance.

Pricing Insights

Mobula operates on a credit-based model, detailed in their pricing documentation, while Zerion utilizes a straightforward request-based pricing system, offering different tiers to fit varying usage needs. Notably:

• Developer Tier: Free for up to 2,000 calls per day with 3 requests per second (RPS)
• Builder Tier: $149 for up to 250,000 calls per month, 10 RPS
• Startup Tier: $499 for up to 1,000,000 calls per month, 25 RPS
• Enterprise: Custom pricing for plans over 2.5 million calls per month and 1,000+ RPS

As it stands, a single request retrieves data for all supported chains, which makes scaling additions cost-effective. Note, however, that deals with DeFi positions and other advanced functionalities are capped at 25% of each plan's quota. Users can also set expenditure limits and manage overages through the dashboard, keeping expenses predictable while accommodating additional needs.

Get Started with Zerion API

Now is the time to obtain your free Zerion API key and experiment with the endpoints using a wallet you are already familiar with, easing the transition.

The Zerion API documentation encompasses an extensive reference, migration maps, sample code in various programming languages, and much more.

For intricacies like field mappings or project-specific challenges, consult the official migration guide. Additionally, if utilizing a coding agent, consider integrating the Zerion API migration skill by executing npx skills add zeriontech/zerion-api-migration and instructing, “Migrate this codebase to the Zerion API.”

If your migration involves nuanced conditions, don’t hesitate to reach out via the chat feature in the Zerion API dashboard for assistance.
