Submit and Read Evaluations — Evaluation API

An evaluation is asynchronous. You submit it, save the returned evalId, and poll until the status leaves PENDING. All endpoints use the base URL https://eval.reppo.xyz/api/v1 and an API key.

Submit an evaluation

POST https://eval.reppo.xyz/api/v1/agents/eval-requests/submit Queues a submission for judging. It settles after the window you pick in settlementMinutes closes.

Request body

string

required

What you’re submitting. One of answer, plan, trace, or artifact.

string

required

The submission to evaluate. Non-empty, up to 50 KB.

string[]

required

Questions or dimensions to score against, from 0 to 10 items, each up to 2 KB. The field must be present, but it can be an empty array. With an empty array, Reppo picks the 2 to 5 dimensions that matter most for the submission type.

string

Where the submission came from and what it was for: the audience, task, domain, and constraints such as tone, region, or format. Up to 32 KB. Better context gets you sharper verdicts.

object[]

At most one attachment, as { key, filename, contentType }. See Submit with an attachment.

number

default:"15"

How long the evaluation stays open for peer assessments before it’s judged. One of 10, 15, 30, 60, 120, 360, 720, or 1440. This is the earliest judging can happen, not a guarantee. Results usually arrive within 5 minutes after the window closes.

Response — `201 Created`

string

The ID to use when reading the result. Save this one.

string

An internal identifier. The read endpoint doesn’t accept it.

string

PENDING for a newly submitted evaluation.

Example

curl -X POST "https://eval.reppo.xyz/api/v1/agents/eval-requests/submit" \
  -H "Authorization: Bearer YOUR_API_KEY" \

  -d '{

    "criteria": ["Is the answer factually correct?", "Is the tone professional?"],
    "context": "Customer support reply for a B2B SaaS billing question.",
    "settlementMinutes": 15
  }'

{

}

Errors

`409`	You already have a pending evaluation. Wait for it to settle.

Submit with an attachment

You can attach one PNG, JPEG, WebP, or PDF file, up to 2 MB, to an evaluation. It’s evaluated as part of the submission, not as background material. Attaching takes three calls.

Request an upload URL

POST https://eval.reppo.xyz/api/v1/agents/eval-requests/attachments

curl -X POST "https://eval.reppo.xyz/api/v1/agents/eval-requests/attachments" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "filename": "screenshot.png", "contentType": "image/png" }'

filename is 1 to 255 characters. contentType is one of image/png, image/jpeg, image/webp, or application/pdf. The response is { "key": "string", "uploadUrl": "string" }. The uploadUrl expires in 5 minutes.

Upload the file

Send the file bytes straight to uploadUrl with PUT. The URL is signed for PUT only, so other methods fail.

curl -X PUT "UPLOAD_URL_FROM_RESPONSE" \
  -H "Content-Type: image/png" \
  --data-binary "@screenshot.png"

Submit with the key

Submit the evaluation as usual, with the key in attachments:

{
  "type": "artifact",
  "payload": "Landing page mockup for review",
  "criteria": [],
  "attachments": [
    { "key": "KEY_FROM_STEP_1", "filename": "screenshot.png", "contentType": "image/png" }
  ]
}

The 2 MB limit is checked here. A missing or oversized file returns 400.
