• 1s_get_api_overviewAPI Overview

  High-level summary of the OneSource REST API: how many operations it exposes, the tags they are grouped under, the networks it routes, the payment protocols it accepts, and a handful of sample endpoints. Start here when you do not yet know what the API covers. Free, no authentication required.

• 1s_get_authentication_guideAuthentication Guide

  How to authenticate to the OneSource REST API — an API key from a subscription, x402 (USDC on Base), or MPP (USDC.e or pathUSD on Tempo) — and how to choose between them. This covers calling the REST API directly; to configure this MCP server, call 1s_setup_check. Free, no authentication required.

• 1s_get_endpoint_referenceEndpoint Reference

  Full reference for a single OneSource REST API endpoint: parameters, request body, example response, price, use cases, and a ready-to-run curl command. Accepts an operation ID or a path. Use 1s_list_endpoints or 1s_search_use_cases first if you do not know which endpoint you need. Free, no authentication required.

• 1s_get_payment_infoPricing & Payment

  Pricing and payment protocols for the OneSource REST API — which rails it accepts, the price range per call, and the recipient address. Pass an endpoint for that endpoint's specific price. This describes what the API charges; 1s_batch_config changes what this server pays with. Free, no authentication required.

• 1s_list_endpointsList Endpoints

  List OneSource REST API endpoints with their method, path, per-call price, and a one-line summary. Pass a tag to narrow the list to one area of the API. Free, no authentication required.

• 1s_list_networksDocumented Networks

  List the networks the OneSource REST API can route to, as declared by its published specification, and how to select one on a call. This is the documented roster; 1s_network_info queries a chain live. Free, no authentication required.

• 1s_search_docsSearch Docs

  Search the OneSource developer documentation by keyword and return the best-matching sections. Use this for conceptual questions — getting started, guides, concepts, how-tos. For the parameters and response of one specific endpoint, use 1s_get_endpoint_reference instead. Free, no authentication required.

• 1s_search_use_casesFind Endpoint by Task

  Find the OneSource REST API endpoints that fit a task described in plain language (for example "check who owns an NFT" or "decode a transaction"). Use this when you know what you want to do but not which endpoint does it. Free, no authentication required.
