Send a request

Examples use the selected endpoint’s public parameter definitions. Replace the API key and example media, then send the request from your server.

SDKs & integrations

POSThttps://api.spicyapi.ai/v1/chat/completions

API authentication

Keep the API key in the server environment variable SPICY_API_KEY. Use Bearer authentication and Content-Type: application/json for JSON requests.

Authorization: Bearer $SPICY_API_KEY

curl --fail-with-body -sN https://api.spicyapi.ai/v1/chat/completions \
  -H "Authorization: Bearer $SPICY_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $(uuidgen)" \

  "model": "xiaomi/mimo-v2.6-flash/chat",
  "messages": [
    {
      "role": "user",

    }

Generated from this model’s input schema — the same one the API validates every request against.

Keep one Idempotency-Key for each logical request. After a network interruption, do not automatically resend with a new key; retain request_id to investigate the accepted request. Idempotency does not replay an earlier chat stream.

Input parameters

Place the model parameters directly in the JSON request body alongside model. This endpoint does not use an input wrapper.

messagesarray<object>Required

For a Flash digest, keep the agenda and recording references in messages; send video and audio inline within the combined 14 MB allowance, and retain tool_call_id for tool replies.

Default: Not specified
Constraints: minItems:1
maxItems:256

messages[].namestringOptional

Optional name identifying the speaker within its role.

response_formatobjectOptional

Ask Flash for text or structured JSON through response_format, then verify extracted fields in your own validator.

Default: Not specified

tool_choicestring | objectOptional

For Flash office assistants, prefer tool_choice=auto: Xiaomi documents other choices as behaving like auto, so required or a named function does not guarantee a call.

Default: Not specified

parallel_tool_callsbooleanOptional

Enable parallel proposals in Flash when separate lookups do not depend on one another; the application still performs those lookups.

Default: true

toolsarray<object>Optional

Describe up to 128 functions Flash can propose for office work; your code checks arguments before updating a calendar or ticket.

Default: Not specified
Constraints: maxItems:128

top_pnumberOptional

For Flash without reasoning, top_p ranges from 0.01 to 1; change it separately from temperature when testing digest consistency.

Default: Not specified
Constraints: minimum:0.01
maximum:1

temperaturenumberOptional

Flash allows temperature from 0 to 1.5 only at reasoning_effort=none; with reasoning active, sampling uses 1.0 and top_p 0.95.

Default: Not specified
Constraints: minimum:0
maximum:1.5

stopstring | arrayOptional

For Flash extraction, stop accepts one sequence or up to four; choose a delimiter that cannot truncate a legitimate field, as the matched delimiter is omitted.

Default: Not specified
Constraints: minLength:1
minItems:1
maxItems:4

reasoning_effortstringOptional

Flash offers none, minimal, low, medium and high, with high selected initially; test none on extraction before increasing effort for ambiguous notes.

Default: "high"
Allowed values: "none""minimal""low""medium""high"

max_tokensintegerOptional

Flash starts with max_tokens at 4,096 and permits up to 131,072; reasoning uses that same allowance, so check finish_reason on long digests.

Default: 4096
Constraints: minimum:1
maximum:131072

With stream set to false, the request returns the completed chat response directly. Read choices[].message; no task polling is needed. Set stream to true when your client supports Server-Sent Events.

This is a chat model, so it works wherever the OpenAI chat API works: keep your client, change the base URL, and select this model by its ID.

Point any OpenAI-compatible client here

export OPENAI_BASE_URL="https://api.spicyapi.ai/v1"
export OPENAI_API_KEY="$SPICY_API_KEY"

aider --model openai/xiaomi/mimo-v2.6-flash/chat

Anything that speaks the OpenAI chat API works the same way — SDKs, the Vercel AI SDK, LangChain, aider, Cline. The MCP server and the spicyapi CLI cover asynchronous media tasks. Per-tool setup is in the developer hub.

Use it in SillyTavern and roleplay apps

In SillyTavern, RisuAI, Agnai or any app with an OpenAI-compatible setting, paste the base URL below and your API key, then pick xiaomi/mimo-v2.6-flash/chat as the model. Browser calls are allowed, and sliders this model does not take are ignored instead of rejected.

Base URL: https://api.spicyapi.ai/v1
Model: xiaomi/mimo-v2.6-flash/chat

The embedded panel reads the same schema as this page, so it cannot drift from the API. If your docs need the content to be searchable, read the JSON under /api/embed/models/ and render it yourself.
