How these are rankedShowHide
Rule. Every listing in OneSource’s own category (Data Tool) that carries a Sato Score, ordered by score tier, observed liveness, deploy-spec and reproduced-install evidence, and chain overlap with OneSource.
This page ranks peers on how open, active and verifiable each one is — the same evidence Sato Hub publishes everywhere else. It is not a quality, safety or performance ranking, it declares no winner, and it cannot tell you which of these fits your codebase. A Sato Score is not an audit: none of these has been security-reviewed by Sato Hub, and a listing with no earned verification is self-reported.
| # | Alternative | Sato Score | Liveness | Chains | Differs on |
|---|---|---|---|---|---|
| 1 | Trading-intelligence API for Robinhood Chain and Solana (KOL trades, DEX tape, deployer reputation) with MCP, SDKs, ElizaOS plugin and x402 pay-per-call. no deploy spec on record | High | Active · 18d ago | Robinhood Chain, Solana | Also on Solana; does not list Ethereum; partly open source. |
| 2 | Zerion✓ reproduced Wallet and DeFi data provider offering portfolio, positions, transactions, PnL, and prices across many chains, with an agent-accessible API. npm install -g zerion-cli install reproduced by Sato Hub | High | Active · 25d ago | Ethereum, Base, Arbitrum, Optimism, Polygon, Avalanche, BNB Chain, Multichain, Solana, Tron, Monad | Also on Base, Arbitrum, Optimism, Polygon and 6 more; does not list Robinhood Chain; partly open source; deploys as npm, MCP server, API. |

| 4 | Skim✓ reproduced Skim is a data service for agents on Base. npx -y skim-mcp install reproduced by Sato Hub | High | Active · 6d ago | Base | Also on Base; does not list Ethereum, Robinhood Chain; open source. |
| 5 | DefiLlama✓ reproduced Open DeFi analytics dashboard and free API tracking TVL, fees, revenue, volume, and yields across many chains and protocols. pip install defillama-sdk install reproduced by Sato Hub | High | Active · today | Ethereum, Base, Solana, Arbitrum, Optimism, Polygon, Avalanche, BNB Chain, Multichain | Also on Base, Solana, Arbitrum, Optimism and 4 more; does not list Robinhood Chain; open source; deploys as API. |
| 6 | US stock market data API (formerly Polygon.io); agents buy it per request over x402 at agent.massive.com with no account. no deploy spec on record | High | Active · 3d ago | Base | Also on Base; does not list Ethereum, Robinhood Chain; partly open source; deploys as Hosted/Remote. |
| 7 | Free, key-less crypto news and market-data API aggregating Bitcoin, Ethereum, Solana, and DeFi. git clone https://github.com/nirholas/free-crypto-news && cd free-crypto-news && npm install && npm run dev install as documented by the project — not reproduced | High | Active · 2d ago | — | Does not list Ethereum, Robinhood Chain; open source; deploys as API, Docker, MCP server. |
| 8 | MPP Services Directory✓ probed Official Machine Payments Protocol catalog of payment-enabled services, with a web directory, JSON API and read-only MCP server. no deploy spec on record | High | Active · today | — | Does not list Ethereum, Robinhood Chain; partly open source. |

“Differs on” is derived from the records — type, chains, openness and deployment — and states a difference, never a preference. ✓ marks an earned state named as what was checked; none of them is a safety claim.

Questions about alternatives to OneSource
- What are the alternatives to OneSource?
- MadeOnSol, Zerion, Nansen, Skim, DefiLlama, Massive (formerly Polygon.io), cryptocurrency.cv, MPP Services Directory, Chainbase, Arkham are listed in the same category as OneSource (Data Tool), as of 2026-11-07. The order is Sato Score and observed evidence, not a quality judgment.
- Which alternatives to OneSource are open source?
- 3 of 10: Skim, DefiLlama, cryptocurrency.cv. Openness is read from each project's own published license or repository.
- Which alternatives run on the same chains as OneSource?
- 6: MadeOnSol, Zerion, Nansen, DefiLlama, Chainbase, Arkham. Chain support is self-declared by each project unless a named check says otherwise on its listing.
- Has Sato Hub verified any of these?
- Sato Hub reproduced the documented install for 4 of them: Zerion, Nansen, Skim, DefiLlama. Reproducing an install means the documented setup was actually run — it is not a security review, and Sato Hub holds no security assessment of any of these.
- How is this list of alternatives built?
- It is a rule over live records, not a hand-written list: every listing in OneSource's own category that carries a Sato Score, ordered by the same evidence the rest of the site ranks on — Sato Score tier, whether an endpoint answered our probe, whether a deploy spec exists and was reproduced, a sustained observed record, and chain overlap with OneSource. It is rebuilt from the records, so it changes when they do.
