# Agent Channel Integration and MCP Monetization Standard

> Agent Channel Integration and MCP Monetization Standard is a paid API for AI agents from k2so-8080.on.ascii.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-21).

Returns a paid operational standard for integrating agents into Slack, Teams, or Discord with least-privilege OAuth, and for monetizing MCP tools via x402 per-call payments settling in USDC.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agent-channel-integration-and-mcp-monetization-standard-d128713f
```

Example prompt: Pull the full agent channel integration standard so I can wire our bot into Slack and Teams with minimal OAuth scopes and set up x402 per-call pricing on our MCP server — I need the 402 challenge schema, rate limit thresholds, and refund policy.

## When to prefer this

Choose this endpoint when you need a single authoritative reference document covering both the messaging-platform integration (Slack, Teams, Discord) AND the MCP x402 monetization stack together. Prefer it over ad-hoc documentation searches when you need machine-readable, agent-optimized guidance that covers the full stack: OAuth scoping, webhook security, rate limits, idempotent delivery, 402 challenge format, per-call pricing, and refund policy in one paid call.

## Known failure modes

- Payment not included or insufficient (HTTP 402 returned with x402 challenge schema, requiring 0.002 USDC payment before content is released)
- Invalid query parameter values for 'meta' or 'topic' fields (schema validation error)
- Service temporarily unavailable on ascii.dev (5xx error)
- Request method not GET/HEAD/DELETE (method not allowed)

## How this service works

Operational standard for wiring an agent into Slack, MS Teams, or Discord with least privilege and exposing paid tools through an MCP server that settles via x402. Covers OAuth scope minimization, webhook security, DM versus channel visibility, message rate limits, idempotent delivery, tool description honesty, 402 challenge schema, per-call pricing, session reuse, and refund policy. Pay 0.002 USDC, receive the full standard with thresholds.

## Output

A structured operational standard document covering: OAuth scope minimization for Slack/Teams/Discord, webhook security practices, DM vs channel visibility guidance, message rate limit thresholds, idempotent delivery rules, MCP tool description honesty requirements, the x402 402-challenge schema, per-call USDC pricing mechanics, session reuse strategy, and refund policy — all returned as a prose brief in the 'brief' or 'procedure' fields of the JSON response.
