How this service works
A2A (Agent2Agent) protocol JSON-RPC endpoint, SendMessage only. Authorizes up to $0.75 (the highest-priced skill); settlement charges the invoked skill's real per-skill price. Base (EVM) only -- for Solana use the REST or MCP endpoints. See /.well-known/agent-card.json for the skill catalog and per-skill pricing.
Output
A JSON-RPC response conforming to the A2A protocol, containing the result of whichever TariffMonkee skill was invoked — could be rendered page Markdown, search results, structured extracted data, screenshots, PDFs, or other skill-specific outputs depending on the skill called.
Example use cases
Web content fetch via agent protocol
“Use TariffMonkee's A2A endpoint to fetch and render the page at https://techcrunch.com/latest and return it as clean Markdown — send it as a JSON-RPC SendMessage.”
Search query dispatched by agent
“Route a search query for 'best AI frameworks 2025' through TariffMonkee's A2A gateway using the SendMessage method and bring back the top results.”
AI-readiness check for a website
“Send a TariffMonkee A2A message to check whether https://myshop.io is AI-ready — I want to know about its schema.org markup and crawlability.”
Technical details
Endpoint
POSThttps://tariffmonkee.com/paid/a2aWhen to prefer
Prefer this endpoint when your agent is already speaking the A2A (Agent2Agent) protocol and wants a single stable endpoint to dispatch multiple different TariffMonkee skills (web fetch, search, screenshot, PDF, structured extraction, AI-readiness checks) under one flat $0.02 per call pricing model. It is ideal for agent orchestration frameworks that route tasks dynamically based on the skill catalog at /.well-known/agent-card.json, rather than hardcoding individual REST endpoints per capability.
Side effects
- Payment not settled — x402 payment failure returns an error before skill execution
- Invalid JSON-RPC body — malformed SendMessage payload returns a parse or invalid request error
- Unknown or unsupported skill — if the message targets a skill not in the catalog, an error is returned
- Network timeout — rendered browser skills may time out on slow pages
- Rate limiting — excessive calls in a short window may be throttled
