SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill eliminates the manual work and friction of accessing paid APIs that return HTTP 402 Payment Required responses, which block automated workflows, AI agents, and programmatic access to paid services without human intervention to handle payment steps.

Core Features & Use Cases

  • MPP v1 Payment Automation: Automatically handles Machine Payment Protocol 402 challenges via the Tempo CLI, removing manual payment steps for supported services.
  • Cross-Chain Token Funding: Swaps and bridges tokens from any supported EVM chain to fund Tempo wallets using the Uniswap Trading API, supporting any ERC-20 token the user holds.
  • x402 Protocol Support: Handles x402 v1 EIP-3009 payment flows for services using the newer x402 standard, with secure off-chain signature authorization.
  • Use Case: An AI agent building a data pipeline that pulls from a paid market data API can use this Skill to automatically pay for access, fund its wallet when balance is low, and retry failed requests without human input.

Quick Start

Use the pay-with-any-token skill to automatically handle a 402 Payment Required response when accessing a paid API, including funding your Tempo wallet and completing the payment transaction without manual steps.

Frequently Asked Questions about pay-with-any-token

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I automate HTTP 402 Payment Required responses for paid APIs?▼

Automate HTTP 402 Payment Required responses by resolving payment challenges via MPP v1 or x402 v1 protocols, enabling programmatic API access without manual payment steps. This handles the full end-to-end workflow including wallet funding and transaction retries.

Can I use any ERC-20 token to pay for API access through Uniswap?▼

Use any ERC-20 token to pay for API access by executing on-chain swaps via the Uniswap Trading API. The workflow cross-chain bridges and swaps tokens from supported EVM chains to fund your Tempo wallet automatically.

What is the x402 EIP-3009 protocol for crypto API payments?▼

The x402 protocol handles EIP-3009 crypto API payment flows using secure off-chain signature authorization. It serves as a newer standard for services requiring Payment Required responses to grant automated access.

How do AI agents handle Machine Payment Protocol 402 challenges?▼

AI agents handle Machine Payment Protocol 402 challenges by using the Tempo CLI to automatically process payments. This removes manual intervention when agents encounter blocked paid services during automated workflows.

Do I need to manually approve crypto token swaps for 402 API payments?▼

You do not need to manually approve crypto token swaps entirely, but the workflow includes mandatory user confirmation gates for all transactions. This ensures secure and compliant payment execution for every API access payment.
