Includes parameters, response shapes, examples, and implementation notes from the 0xArchive contract. Source OpenAPI: 0xArchive API 1.10.0; 240 paths; 241 component schemas. Get every USDC flow into and out of HyperCore, oldest first in execution order: Arbitrum bridge deposits (`deposit`) and withdrawals (`withdraw`), and transfers from and to HyperEVM (`evm_in`, `evm_out`), which is also how CCTP moves USDC in and out. Each event names the HyperCore account in `user`. Included with the Build, Pro, Scale and Enterprise plans. A key on another plan receives 403 `forbidden` naming the dataset, the plans that include it and where to upgrade, and is not charged. **Coverage:** from the first recorded flow, 2025-09-27 09:33 UTC. A window that ends before it returns an empty page with `meta.coverage_from` and `meta.notice`; a window that straddles it is served from it. **Pagination:** pages follow execution order, so a page boundary inside a bridge batch neither repeats nor skips an event. A page reads at most 31 days of history, so with a selective `min_usd` a page can hold fewer than `limit` events, or none, and still carry `meta.next_cursor`. Pass the cursor back with the same filters until `meta.has_more` is `false`; never stop on a short or empty page. **Recent events:** an event in the last 3 hours can still be added after you have read past it, when a gap in the live record is repaired. Re-read the last 3 hours and deduplicate on `id`. **Credits:** 1 credit per 1,000 events returned, at least 1 per request. ## Route Metadata | Field | Value | | - | - | | Method | `GET` | | Path | `/v1/hyperliquid/usdc-flows` | | operationId | `getUsdcFlows` | | Tag | Hyperliquid - USDC Flows | | Family | Hyperliquid Core | | Deprecated or legacy | no | ## Human endpoint reference Open [`GET /v1/hyperliquid/usdc-flows`](https://docs.0xarchive.io/api-reference/hyperliquid--usdc-flows/get-hyperliquid-usdc-flow-events) for authentication, parameters, responses, and examples. ## Implementation context * [USDC flows paging and recent events](https://docs.0xarchive.io/rest-api/usdc-flows.md) ## Request Parameters ### Query Parameters ```json theme={"theme":"github-dark"} { "$schema": "https://json-schema.org/draft/2020-12/schema", "title": "getUsdcFlows query parameters", "type": "object", "properties": { "start": { "description": "An instant: Unix milliseconds, or an RFC 3339 string such as `2026-01-01T00:00:00Z` (encode a `+` offset as `%2B`).
