**Category:** Government & Public Data | **Website:** [opportunitydesk.org/category/grants/](https://opportunitydesk.org/category/grants/) | **Docs:** [parse.bot/marketplace/698f6e64-ff4c-4f4f-93df-87dec233c7c1/opportunitydesk-org-api](https://parse.bot/marketplace/698f6e64-ff4c-4f4f-93df-87dec233c7c1/opportunitydesk-org-api)

Pay-per-use API proxy for Locus Pro. Each call burns credits from your workspace balance.

## Access

**Base URL:** `https://api.beta.paywithlocus.com/api/wrapped/credits/opportunity-desk/`
**Auth:** `Authorization: Bearer <LOCUS_CREDITS_SECRET_KEY>` (an `lcr_` secret key or a scoped `lcac_` agent credential)
**Required header:** `Idempotency-Key: <fresh UUID per call>`. A retry with the same key replays the stored result without a new charge.
**Response:** the provider response after any endpoint-specific normalization. `X-Locus-Credits-Charged` carries the charge and `X-Locus-Credits-Balance` the remaining balance. Insufficient credits return `402` before the provider is called.
**Pricing:** estimated costs below are USD. Locus debits the credit equivalent at your workspace rate.

Full call contract: https://docs.paywithlocus.com/api-reference/introduction

> Using a Pay With Locus wallet key (`claw_` prefix)? Wallet routes are documented separately: https://docs.paywithlocus.com/wrapped-apis/for-agents

## Endpoints

### Get grant details

Get detailed information about a specific grant by its slug or numeric ID. Parses the grant post content to extract structured fields: deadline, eligible countries, eligible applicants, grant amount, per-sector/individual amount details, and the external application URL. Provide either slug (from list_grants results) or id.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `id` | string | No | Numeric post ID of the grant (e.g. '177274'). Obtain from list_grants results. |
| `slug` | string | No | URL slug of the grant post (e.g. 'charity-accelerator-program-2026'). Obtain from list_grants results. |

```bash
curl -X POST https://api.beta.paywithlocus.com/api/wrapped/credits/opportunity-desk/get-grant-details \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"id":"<string>","slug":"<string>"}'
```

### List grants

List grant opportunities from Opportunity Desk with optional search filtering and pagination. Returns grant summaries including title, date, link, and excerpt. Pagination is controlled by page and per_page parameters.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `page` | integer | No | Page number for pagination. |
| `per_page` | integer | No | Number of results per page (1-100). |
| `search` | string | No | Free-text search query to filter grants by keyword. |

```bash
curl -X POST https://api.beta.paywithlocus.com/api/wrapped/credits/opportunity-desk/list-grants \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"page":"<integer>","per_page":"<integer>","search":"<string>"}'
```
