What it returns

The fault-proof dispute games opened on the parent chain for one OP-Stack L2, newest first, 50 per page: each game's index, type, contract, the L2 block its claim names, when it was created and resolved, and who won. claimedL2BlockNumber is what the game claims, not a checked block: anyone may open a game, and a false claim ends challenger_wins. Keep passing nextCursor back as cursor until it is null. How many games there are is in rollup-settlement-totals.

Request

Send your key in the x-dex-data-key header. Replace each <placeholder> with a real value.

curl -H "x-dex-data-key: $DEXDATA_API_KEY" \
  "https://api.dexdata.io/api/external/chain-analysis/dispute-games/OP"

Parameters
Parameter	Description
`cursor` query · string · optional	An opaque cursor from a previous response's `nextCursor`, for the next page. It only pages the chain it was issued for; an empty one, or one over 256 characters, is a 400 (enforced after the API-key gate).
`chain` path · string · required	OP only; every other chain returns 400.

Response fields

A JSON response. Every field is always present; null means the value could not be established, never zero.

Charged only when the call succeeds. Prices as of 2026-10-30; the current ones are always in the API reference.

How far an L2's settlement on its parent chain has come
How many games there are.
Rollup batch settlement
One batch's or block's standing on the parent chain.
A block's internal calls
Every internal call one block executed — calls, delegatecalls, creates and self-destructs, with value, gas and whether each reverted — in execution order, a page at a time. RHC, ETH, OP and SCROLL.
Solana protocol parameters: network, epochs, inflation, minimum stake, rent
Which network this is (genesis hash), slots per epoch, the inflation schedule and rate in force, the smallest stake delegation, and the balance an account needs to be rent-exempt.
Solana network nodes: client software, versions and public RPC endpoints
Every node in the Solana network now: the client software and version each runs, the split across clients and versions, how many expose public RPC, and their addresses.
Is this Solana blockhash still valid?
Whether a transaction built on a given Solana blockhash would still be accepted right now, read at a chosen commitment; a blockhash expires about 150 blocks (60 to 90 seconds) after its block.
