RobinhoodRPC vs Mobula
A wallet and portfolio data API with the broadest set of derived metrics on this chain — the only competitor computing P&L at all.

One line changes
Both endpoints speak standard JSON-RPC over HTTPS and WebSocket, so ethers, viem and web3.py need no code changes. Everything we add is additive.
- Our extra namespaces are additive — nothing you already call changes shape.
- Run both in parallel and diff the responses before you cut over. Our free tier makes that cost nothing.

◑ means partial or undocumented — not a criticism, just an honest mark where public information does not settle it. If Mobula has shipped something since 2026-08-27, tell us and we will correct this page.
What Mobula does not cover
Sourced gaps, not speculation.
P&L without corporate-action adjustment
Their portfolio metrics are computed crypto-natively from raw balances. Across a dividend or split those figures are arithmetically wrong, and the error compounds — this is the most concrete correctness claim in this market.
REST only
Documentation shows no WebSocket streaming, which is a meaningful limitation on a chain producing blocks every 100 milliseconds.
No price reconciliation
Prices are DEX-observed. The divergence from the underlying equity is not computed.
Run us side by side
Do not switch on a comparison table. Point both at the same workload and compare the answers.
Get a free key
No card. Point a second RPC_URL at us and mirror your traffic.
Diff the responses
For standard eth_* calls the answers should be identical. If they are not, that is worth knowing about whichever provider is wrong.
Ask for a position at a pre-split block
This is the test that separates providers. Request a wallet's value at a block before a corporate action and check whether the multiplier applied is the one from that block or from today.
Moving from Mobula
Endpoint shapes, auth differences, and the handful of behaviours worth checking before you cut over.
The questions migrations actually raise.
Mechanics, gotchas, and tier gates, answered plainly. Anything missing lives in the migration guide.
It is a claim about arithmetic, not quality. Robinhood stock tokens keep raw balances static and express corporate actions through uiMultiplier(). Any P&L computed from raw balances without that term is incorrect after a split or dividend. It reproduces or it does not — run the check.
Every claim links to Mobula's own documentation and carries the date it was checked. We publish a case for choosing them, and we correct this page when they ship something new — a comparison that ages badly is worth less than no comparison.
RPC is free. Paid plans start at $50 per month for the data layer, with $25 for the first month.

A free key, a second RPC_URL, and the pre-split-block test. That is the whole evaluation.
