description: Find, compare, and safely integrate verified x402 resources through the TOLL·402 MCP server. Use when a developer needs an x402 API or MCP service, wants to compare price or verification evidence, needs quote-only integration code, or asks an AI coding agent to add an x402 service without making a payment.

# TOLL·402 Integration

## Workflow

1. Inspect the current repository and identify the required capability, runtime, network constraints, and acceptable unit cost.
2. Call `search_services` with the capability. Prefer `curation: curated` and `verification: direct-quote` when results exist; relax one constraint at a time when they do not.
3. Call `get_resource` for the strongest candidates. Inspect the exact method, URL, input, payment options, source provenance, and check dates.
4. Use `compare_resources` when two or more credible candidates remain. Compare cost per completed task, not only the displayed per-call number.
5. Call `check_current_quote` for the selected record. Treat its response as the latest stored dated check, not a new probe.
6. Call `get_connection_recipe` for the repository language or active coding agent.
7. Implement the quote-only path with the repository's existing patterns and tests. Explain the separate step required to enable a wallet-backed paid request.

## Trust Boundaries

- Never request, print, store, or transmit a private key or seed phrase.
- Never make a paid request unless the user explicitly authorizes that exact payment and the repository already has an approved local signing path.
- Do not describe a live 402 quote as paid-call verification.
- Prefer exact resource records over provider-level claims.
- Keep the resource id and last check date in the handoff so another developer can reproduce the choice.
- For POST, PUT, PATCH, or DELETE routes, inspect provider-approved test input before running any request.

## Handoff

State the selected resource, why it won, its published price and network, the date and scope of its latest check, files changed, validation performed, and the remaining step before a paid production call.
