Description
The prediction market interface for AI agents. Trade Polymarket and Kalshi through one API with self-custody wallets, safety rails, and smart context.
Usage Guidance
Install if you want APIDot image API integration guidance. Treat APIDOT_API_KEY as a real secret, keep it server-side, and review any generated integration code before using it with live credentials.
Capability Assessment
Purpose & Capability
The stated purpose is APIDot image generation and editing API guidance, and the reviewed artifact is aligned with that purpose through docs routing, async task guidance, polling, webhook notes, and examples.
Instruction Scope
The instructions are scoped to helping users integrate with APIDot and explicitly limit live API calls to cases where the user asks and provides a safe server-side environment.
Install Mechanism
The artifact consists of a single non-executable SKILL.md file with no scripts, package hooks, binaries, or companion files observed.
Credentials
The skill declares optional APIDOT_API_KEY use, which is sensitive but expected for an API integration and paired with guidance to keep it server-side and out of public or logged contexts.
Persistence & Privilege
No local persistence, background worker, privilege escalation, or automatic credential storage is present; any persistence discussed is ordinary application workflow state such as task IDs or generated image URLs.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install simmer - After installation, invoke the skill by name or use
/simmer - Provide required inputs per the skill's parameter spec and get structured output
Version History
v1.24.6
Teach get_markets(tags/q/sort/venue) discovery in the API surface (flip-safe wording)
v1.24.5
Surface backtesting in the on-ramp: learn-more row + graduation ladder (backtest -> SIM -> real).
v1.24.4
Fix broken get_markets(q=) example -> find_markets(); clarify market-discovery API surface
v1.24.3
- Version bump to 1.24.3.
- SKILL.md content updated (minor edits).
- skill-card.md file removed.
v1.24.2
Consolidate the simmer overview to a single canonical source (SDK skill). Add simmer-mcp-setup reference row. Per-agent OWS activation detail now lives in simmer-wallet-setup.
v1.24.1
- SKILL.md updated to remove "Start here" from the description and clarify introductory language.
- Metadata version bumped to 1.24.1.
- Minor copy and formatting edits; no changes to functionality or API.
- No changes to code, API surface, or documented safety rails.
v1.24.0
Wallet row now points to simmer-wallet-setup skill (OWS recommended path) instead of the docs page
v1.23.2
- Adds explicit guidance to always check result.success after client.trade(), clarifying that trade failures return a TradeResult object and do not raise exceptions.
- Updates the quick start example to include trade failure handling and a code snippet to check result.error.
- Bumps version to 1.23.2 in the metadata.
v1.23.1
v1.23.1 — ASI scanner reframe per engine v2.4.22 calibration. Adds Safety rails (read first) section surfacing bounding mechanisms (paper-default, claim+wallet for real money, $100/$500/50 caps, auto stop-loss, reversibility). Drops named cross-skill links from Where-to-learn-more (replaced with non-named pointers to docs.simmer.markets and clawhub.ai/skills?q=simmer). Quick-start step 3 leads with paper-default and SimmerClient.from_env(). Two factual fixes: reasoning is optional (not required); set_monitor (not set_position_monitor). No API/SDK behavior change.
v1.23.0
Slim flagship to 129 lines (from 426). Tier A scoping per skill catalog reshape: drop wallet/setup duplication (now in simmer-wallet-setup), drop briefing duplication (now in simmer-briefing), trim changelog/example sections. Pre-publish audit applied (TRADING_VENUE declared, orchestration verbs softened to documentation framing). Skill is the entry point — register, trade in $SIM, point at deeper Tier A skills when needed.
v1.22.2
Mirror envVars + primaryEnv into skill.md frontmatter so the registry summary matches the bundle manifest (clawhub.json). v1.22.1 scan flagged metadata inconsistency between the two sources. No functional changes — only metadata alignment.
v1.22.1
Fix displayName: 'Public' → 'Simmer'. Previous versions inherited the folder-basename default because the publish command omitted --name. No content changes.
v1.22.0
Re-scope bundle to skill.md + clawhub.json only (drops accidentally-included design-system, docs, logos, SVGs). Restore v1.20.5 envVars[] schema with WALLET_PRIVATE_KEY required:false. Fixes OpenClaw scanner suspicious verdict caused by bundle pollution + manifest regression in v1.21.0.
v1.21.1
V2 migration: pUSD is the Polymarket V2 collateral (1:1 backed by USDC.e). Updated requirements + venue copy; added cross-link to docs.simmer.markets/v2-migration.
v1.20.5
Schema fix: move WALLET_PRIVATE_KEY to envVars with required:false + add primaryEnv. OpenClaw scanner previously misread v1.20.4 as 'disproportionate'; this version expresses the truth that WALLET_PRIVATE_KEY is only needed for external-wallet mode.
v1.20.4
Restore clawhub.json env declarations (SIMMER_API_KEY, WALLET_PRIVATE_KEY) for OpenClaw moderation alignment. v1.20.3 accidentally omitted this file.
v1.20.3
- Documentation update: SKILL.md updated to version 1.20.3.
- Obsolete file removed: clawhub.json deleted from the repository.
v1.20.2
Version 1.20.2 Changelog
- Added new file: `clawhub.json`.
- Updated documentation in SKILL.md.
- Downgraded version metadata from 1.21.0 to 1.20.0 in SKILL.md.
v1.21.0
**Simmer 1.21.0 – Major documentation update & cleanup**

- Added detailed sections on auto-redeem, external wallet configuration (including Open Wallet Standard), risk exits, and order management.
- Clarified workflow for agents (register, claim, trade, heartbeat) and improved practical code examples.
- Improved explanation of wallet modes, venue support (Polymarket, Kalshi), and configuration steps.
- Removed legacy and internal metadata files, consolidating config into SKILL.md.
