> Blockscout Optimism Deposits Endpoint is a paid API for AI agents from api.blockscout.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-12).

Retrieves a list of Optimism bridge deposits (L1→L2) for a specified chain, including L1 block numbers, timestamps, and transaction hashes on both layers

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability blockscout-optimism-deposits-endpoint-00e58fa3
```

Example prompt: Pull the latest Optimism bridge deposits from Blockscout for chain ID 10 — I need the L1 block numbers, timestamps, and both the L1 and L2 transaction hashes.

## When to prefer this

Use this endpoint when you specifically need Optimism bridge deposit data (L1→L2) with both layer transaction hashes and block-level timestamps, and you want Blockscout's multichain explorer coverage rather than querying an Optimism node directly. Ideal for monitoring, auditing, or reconciling cross-layer bridge activity.

## Known failure modes

- Invalid or unsupported chain_id returns an error or empty response
- Network unavailability from Blockscout API results in timeout
- Chain not indexed by Blockscout may return 404 or empty array
- Malformed chain_id path parameter causes a 400 bad request

## How this service works

Explore crypto activities with Blockscout's multichain search. Find transactions, addresses, tokens, and dapps across top blockchain networks — your go-to explorer for cross-chain blockchain data

## Output

Returns an array of Optimism deposit records, each containing the L1 block number, L1 block timestamp, L1 transaction hash, and the corresponding L2 transaction hash for cross-layer bridge deposits.
