30+ AI tools paid with Bitcoin Lightning. No signup, no API keys, no KYC.
A remote MCP (Model Context Protocol) server that gives AI agents access to image generation, video creation, text generation, speech, translation, image processing, OCR, audiobook conversion, email, SMS, voice cloning, and more — all paid per-use with Lightning Network micropayments.
Add to your claude_desktop_config.json:
{
"mcpServers": {
"sats4ai": {
"url": "https://sats4ai.com/api/mcp"

}For clients that don't support remote HTTP servers, use the bundled stdio proxy:
npx sats4ai-mcpOr in your config:
{
"mcpServers": {
"sats4ai": {
"command": "npx",
"args": ["sats4ai-mcp"]
}
}
}The server URL is:
https://sats4ai.com/api/mcp
This is a remote HTTP server — no local process, no dependencies, no installation needed.

- Agent calls
list_modelsto discover available models and pricing - Agent calls
create_payment— gets a Lightning invoice - Payment is made via the agent's Lightning wallet (e.g., lightning-wallet-mcp)
- Agent calls the tool (e.g.,
image,text) with thepaymentId - Result is returned — base64 image, text, URL, etc.
No API keys. No accounts. No rate limits tied to identity. Just Bitcoin and AI.
When a paid tool fails after payment, the JSON-RPC error response includes refund information:
{
"jsonrpc": "2.0",
"id": 1,
"error": {
"code": -32603,
"message": "Image generation failed",
"data": {
"refund": {
"charge_id": 12345,
"refund_amount": 200,
"lnurl_withdraw": "lnurl1dp68gurn8ghj7..."
}
}
}
}Claim the refund using any LNURL-compatible wallet or the claim_lnurl_withdraw tool from lightning-wallet.
Pair with a Lightning wallet MCP server so your agent can pay autonomously:
{
"mcpServers": {
"sats4ai": {
"url": "https://sats4ai.com/api/mcp"
},
"lightning-wallet": {
"command": "npx",
"args": ["lightning-wallet-mcp"]
}
}
}The agent uses lightning-wallet to pay invoices from sats4ai, enabling fully autonomous AI tool usage.
For direct HTTP integration without MCP, use the L402 API:
# Step 1: Request -> get 402 + Lightning invoice
curl -X POST https://sats4ai.com/api/l402/generate-image \
-H "Content-Type: application/json" \
-d '{"input": {"prompt": "a cat in space"}}' -i
# Step 2: Pay the invoice with any Lightning wallet
# Step 3: Re-send with proof
curl -X POST https://sats4ai.com/api/l402/generate-image \
-H "Content-Type: application/json" \
-H "Authorization: L402 <macaroon>:<preimage>" \
-d '{"input": {"prompt": "a cat in space"}}'Full L402 docs: sats4ai.com/l402 | Code examples: sats4ai-l402-examples
Machine-readable endpoints for agent discovery:
# Full service catalog with pricing, quality benchmarks, and performance metadata
GET https://sats4ai.com/.well-known/l402-services
# MCP tool catalog with latency (p50/p95), reliability, and failure modes
GET https://sats4ai.com/api/mcp/discovery
# Semantic search — find tools by capability
GET https://sats4ai.com/api/discover?q=translate
# Per-service metadata with enums and input schemas
GET https://sats4ai.com/api/l402/{service}Every paid tool includes performance metadata (latency p50/p95, reliability rating, known failure modes) so agents can make informed decisions about which tools to call and how long to wait.
