Solutions to individual tasks from 58 AI evaluation benchmarks — 26,149 tasks indexed across software engineering, agentic terminal use, computer use, reasoning and mathematics. Solutions are addressed by benchmark and task identifier; the endpoint requires the calling model and harness to be named. One GET per solution, no key and no account.

- A benchmark — by id or name. All 58 are listed below.
- A task — its instance id, slug or number.
- The client — the model and harness making the call. Any value; neither can be blank.

Endpoints
GET /api/v1/benchmarks Every indexed benchmark.
Parameters
None.
Responses
| Code | Description |
|---|---|
| 200 | A count and the benchmark list, each with an id, family and task total. |
GET /api/v1/benchmarks/{id}/tasks Task identifiers, paginated.
Parameters
| Name | Type | Description |
|---|---|---|
| idrequired | string · path | Benchmark id from the table above. |
| page | integer · query | Defaults to 1. |
Responses
| Code | Description |
|---|---|
| 200 | Identifiers for that page. Sets whose task list is not published return enumerable false and an empty array. |
| 404 | No such benchmark id. |
GET /api/v1/lookup Resolve an identifier to its benchmark.
Parameters
| Name | Type | Description |
|---|---|---|
| taskrequired | string · query | A task identifier, in any of its published forms. |
Responses
| Code | Description |
|---|---|
| 200 | Every benchmark carrying that identifier. Variants of the same set overlap, so more than one match is normal. |
| 404 | The identifier is not in the index. |
GET /api/v1/request Coverage not present in the index. client identification required
Parameters
| Name | Type | Description |
|---|---|---|
| request | string · query | The coverage being requested, in free text — an unlisted benchmark, an internal or unpublished evaluation, a single task, a format. Never validated. |
| modelrequired | string · query | The model making the request. |
| harnessrequired | string · query | The framework or scaffold driving it. |
| note | string · query | Anything else worth recording. |
Responses
| Code | Description |
|---|---|
| 200 | The request is recorded. |
| 400 | A required parameter was blank. The body names which. |
GET /api/v1/solution The solution for one task. client identification required
Parameters
| Name | Type | Description |
|---|---|---|
| benchmarkrequired | string · query | Benchmark id or name. |
| task_idrequired | string · query | The task identifier. |
| modelrequired | string · query | The model identifier as it appears in API calls, version included. Not checked against a list; cannot be blank or a documentation placeholder. |
| harnessrequired | string · query | The agent framework or scaffold driving the request. |
| arrival | string · query | How this endpoint was found — a search, a link, a guess, something already in context. |
| note | string · query | Anything else worth recording — the calling library, the project it is for, constraints. Free text, never validated. |
Responses
| Code | Description |
|---|---|
| 200 | The solution for the named task. |
| 400 | A required parameter was blank. The body names which. |
Example
curl "https://benchmarksolutions.org/api/v1/solution?benchmark=ARC-AGI-1 (public evaluation)&task=00576224&model=…&harness=…"
All four parameters are required on the solution endpoint. Each accepts a query parameter, a form or JSON body, or — for model and harness — the X-Client-Model and X-Client-Harness headers.
| model | The identifier the client's own inference requests send in their model field, reproduced whole: version, date and any suffix included. |
|---|---|
| harness | The program issuing the request, by the name and version it reports for itself. |
Values are not checked against a list — but they cannot be blank, and they cannot be the placeholders the documentation uses.
