Domain knowledge for Singularity Layer — workflow patterns, data models, and gotchas for your AI agent.
The Singularity Layer connects AI agents with a decentralized marketplace of API endpoints, products, and blockchain-integrated agents. This platform bridges traditional API commerce with crypto payments through the x402 protocol and supports ERC-8004/Solana-8004 agent standards.
Marketplace Discovery: Browse listings with rich filtering, search featured and top-rated endpoints, explore categories across supported blockchain networks. Access detailed information about specific products and services.
Endpoint Management: Create, configure, and monitor your own API endpoints with credit balancing, usage analytics, and pricing controls. Set up webhooks for real-time notifications and manage endpoint lifecycles.
Blockchain Agent Integration: Register and manage ERC-8004/Solana-8004 compliant agents using wallet-first authentication. Submit reputation feedback and bind platform endpoints to on-chain agent identities.
Payment Processing: Handle x402 payment challenges for endpoint creation, credit top-ups, and product purchases. Complete transactions using crypto wallets with automatic credit management.
The platform organizes around Endpoints (API services with pricing), Products (purchasable items), Agents (blockchain-registered AI services), and Networks (supported blockchains). Each endpoint maintains credit balances, usage metrics, and webhook configurations.
Authentication uses Personal Access Tokens (PATs) for dashboard operations or endpoint-specific API keys. Wallet signatures are required for blockchain agent operations. Payment flows require two-step challenges: first obtain payment details, then complete with valid X-Payment payload.
Resources provide cached access to featured listings, categories, networks, and agent registries for efficient browsing without repeated API calls.
Connect Singularity Layer to any MCP client in minutes
Operate Singularity Layer? You can take over the listing's metadata.
Take over this listing's metadata — name, description, category, logo, website, contact email, and skill content. Verification is a 6-digit code we email to one of the maintainer addresses your server already publishes in /.well-known/security.txt or /.well-known/mcpbundles.json. Free, takes about a minute.
Connect straight to this server’s public endpoint.

Vault Usage
Agent Vault storage usage and plan for the wallet behind a compute API key: bytes used/reserved, free vs pro plan, caps, and Vault Pro pricing.
Vault List Agents
List the agents registered in Agent Vault for this wallet (OpenClaw, Hermes, pods, and custom --path lineages).
Vault List Snapshots
List completed Agent Vault snapshots (encrypted backups) for this wallet, optionally filtered to one agent. Use this to check WHEN an agent was last backed up.
Vault Delete Snapshot
Permanently delete one Agent Vault snapshot and free its storage. Irreversible — confirm with the user before calling.
Vault Subscribe Pro
Change the wallet’s Agent Vault plan, charged from platform credits. pro = 10 GB + the last 10 snapshots of each agent ($3/month, $30/year); max = 50 GB + unlimited snapshots ($5/month, $50/year); free = cancel at period end. Yearly is two months free. Upgrades are charged immediately and prorated against the unused period; downgrades and cancellations take effect at period end. A plan change never deletes snapshots. ALWAYS confirm the plan and the charge with the user before calling.
Vault How To Backup
How to actually CREATE or RESTORE an encrypted backup. Encryption is zero-knowledge and must run on the machine where the agent lives — this returns the exact CLI/SDK steps.
List Dataset Pricing
What a generated training dataset costs and which models can generate it: per-100-example rates for each managed tier plus the decentralized grid, the maximum size, and the model catalog with published per-million-token rates. No auth, no payment. Call this before quoting a job.
Request Dataset Payment
Step 1 of buying a training dataset: submit the job and get back an x402 payment challenge with the exact price. Nothing is charged and nothing is generated yet. Pass the SAME arguments to create_dataset_with_payment: the server binds the payment to this exact job and refuses a mismatch.
Create Dataset With Payment
Step 2 of buying a training dataset: submit the job again with the signed X-Payment payload and the quote id. Returns in seconds with a dataset id and a claim token; generation then runs in the background. SAVE THE CLAIM TOKEN — it is shown once and is the only way to read the job or download the result.
Get Dataset Status
How a purchased dataset is coming along, and the download link once it is ready. Returns rows done vs target while generating, a presigned JSONL download URL (valid 5 minutes, re-issued each call) when complete, or the refund state if generation failed.
Browse Marketplace
Browse and search the Singularity Marketplace with various filters. Returns listings of endpoints, products, and agentic services.
Get Listing
Get detailed information about a specific marketplace listing by its slug.
Get Featured
Get featured marketplace listings (endpoints and products highlighted by the platform).
Get Top Rated
Get top-rated marketplace listings sorted by average rating.
Get Agent
Get details for a specific ERC-8004 or Solana-8004 agent by network and identifier.
List Categories
List all available marketplace categories.
List Networks
List all supported blockchain networks.
List Agents
List all registered ERC-8004 and Solana-8004 agents.
List My Endpoints
List the endpoints accessible to the dashboard owner behind your MCP access token or endpoint API key. PATs are preferred for owner-wide inventory and require mcp:read or mcp:*.

Create Campaign
Create a fundraiser campaign owned by the dashboard user behind your MCP personal access token. Requires mcp:campaigns:write or mcp:*.
Update Campaign
Update allowlisted fundraiser campaign fields such as title, description, x handle, images, and links. Requires mcp:campaigns:write or mcp:*.
Update Endpoint
Update allowlisted endpoint fields such as metadata, pricing, listing flags, imagery, wallet, payment options, slug, and webhook settings. PATs are preferred and require mcp:endpoints:write or mcp:*.
List My Products
List the products owned by the same dashboard user as your MCP access token or endpoint API key. PATs are preferred and require mcp:read or mcp:*.
Update Product
Update allowlisted product fields including metadata, pricing, listing state, payment options, wallet, branding, and slug. PATs are preferred and require mcp:products:write or mcp:*.
This server facilitates marketplace interactions, allowing users to browse listings, manage endpoints, and set webhooks. It is aimed at developers looking to integrate marketplace functionalities into their applications. It provides MCP tools that your client discovers when it connects (this page may not list every tool name) that AI agents can use through the Model Context Protocol (MCP).
Add the MCPBundles server URL to your MCP client configuration (Claude Desktop, Cursor, VS Code, etc.). The URL format is: https://mcp.mcpbundles.com/bundle/singularity-mcp. Authentication is handled automatically.
Singularity Layer is a remote MCP server. The live tool list is supplied by the server when your MCP client connects, so the count is not fixed on this public page. After you connect in MCPBundles Studio or your client, you will see the tools your session can call. A SKILL.md is still included to guide your agent on capabilities and workflows.
Singularity Layer uses API Key. Singularity Layer requires credentials. Connect via MCPBundles and authentication is handled automatically.
