# Settld MCP Payments Skill

This skill teaches OpenClaw agents to use Settld for paid MCP tool calls.

## What This Skill Enables

- Discover Settld MCP tools (`settld.*`)
- Run paid tool calls with x402 challenge/authorize/retry flow
- Return verifiable payment/settlement headers from tool responses
- Produce audit-grade artifacts and receipts in Settld

## Prerequisites

- Node.js 20+
- Settld API key (`SETTLD_API_KEY`)
- Settld API base URL (`SETTLD_BASE_URL`)
- Tenant id (`SETTLD_TENANT_ID`)
- Optional paid tools base URL (`SETTLD_PAID_TOOLS_BASE_URL`)

## MCP Server Registration

Use the server definition in `mcp-server.example.json`.

Server command:

- command: `npx`
- args: `["-y","settld-mcp"]`

Required env vars:

- `SETTLD_BASE_URL`
- `SETTLD_TENANT_ID`
- `SETTLD_API_KEY`

Optional env vars:

- `SETTLD_PAID_TOOLS_BASE_URL`
- `SETTLD_PROTOCOL`

## Agent Usage Pattern

1. Call `settld.about` to verify connectivity.
2. For paid search/data calls, use:
   - `settld.exa_search_paid`
   - `settld.weather_current_paid`
3. For agreement lifecycle demo calls, use:
   - `settld.create_agreement`
   - `settld.submit_evidence`
   - `settld.settle_run`
   - `settld.resolve_settlement`

## Smoke Prompts

- "Call `settld.about` and return the result JSON."
- "Run `settld.weather_current_paid` for Chicago in fahrenheit and include the `x-settld-*` headers."

## Safety Notes

- Treat `SETTLD_API_KEY` as secret input.
- Do not print full API keys in chat output.
- Keep paid tools scoped to trusted providers and tenant policy.
