# Stoa

> Stoa builds business infrastructure for agents and the humans who make services available to them. Stoa helps MCP, x402, paid API, and agent-tool teams prepare services for real agent commerce: clear listings, supported claims, payment evidence, and outputs agents can read.

## Core Pages

- [Stoa](https://stoa.tools/): agent-commerce infrastructure for MCP servers, x402 paid APIs, and agent-tool launches.
- [Agent-readable offers](https://stoa.tools/offers.json): machine-readable service catalog, deliverables, start instructions, and boundaries.
- [Validator MCP Server Bundle](https://stoa.tools/stoa-validator-mcp-server/): public package for local MCP listing self-checks and x402 payment-evidence checking.
- [Launch Review Skill Package](https://stoa.tools/stoa-x402-mcp-launch-review/): public self-check artifacts and examples.

## Positioning

- Launch readiness: help human builders make services listable, chargeable, callable, and evidence-backed.
- Agent-readable services: turn repeated readiness checks into payment-evidence, policy, receipt, failure, and service-readiness tools that agents can evaluate or eventually call directly.
- Trust and evidence are part of Stoa's work, not the whole company identity.

## Current Offers

- MCP Listing Review: $49 applied report for listing readiness, supported claims, and directory submission issues.
- x402 Payment Evidence Checker: $149 applied report separating real external payment evidence from self-pay mechanics, failed discovery, missing output, and unsafe logs.
- Full Launch Review and Repair: $299 applied review with listing copy, blocked claims, payment-risk findings, and next launch/payment test.

## Agent-Readable Boundaries

- Public code and examples are proof/self-check artifacts, not a production hosted API.
- Paid work requires scoped buyer input and confirmation before any payment destination, checkout link, invoice, wallet address, or live x402 route is sent.
- Stoa does not claim marketplace acceptance, durable ranking, production readiness, legal/compliance approval, security certification, or external buyer revenue unless direct evidence is published.
- Agent-facing services and microservices are a strategic direction, not a current hosted production API claim.
