Use with AXON

Run this through your governed agent wallet.

  1. 01
    Bootstrap AXON once with npx @axon402/init.
  2. 02
    Use the AXON runtime MCP tools to search_x402_services or inspect_x402_offer for this service.
  3. 03
    Quote, test-buy, then run the governed paid fetch through AXON.

Send this

Prompt for your agent

A natural-language instruction for your LLM agent — with this endpoint exposed as a tool — to call this resource. Not sent to the endpoint; the endpoint consumes the JSON body below.

Pasting this prompt into a raw ChatGPT or unconfigured agent will notexecute the paid endpoint flow. Run it through an agent with the AXON runtime / MCP tools exposed (see “Use with AXON” above) so the 402 challenge, quote, and governed fetch are handled for you.

“Check if this transaction calldata is safe to execute for a token swap.”

Endpoint request body

The JSON payload your agent sends to the endpoint.

application/json
{
  "data": "0x095ea7b3...",
  "from": "0x1234...",
  "chain": "ethereum",
  "intent": "approve token for DEX swap",
  "expectedFunction": "approve"
}

Advanced HTTP details

For integrators who need the raw protocol surface. Most agents should use AXON above instead of calling these directly.

curl fallback

curl https://flows.litprotocol.com/api/flows/txn-checker/invoke \
  -H "Content-Type: application/json" \
  -H "X-PAYMENT: [signed_payment_envelope]" \
  -d '{"data":"0x095ea7b3...","from":"0x1234...","chain":"ethereum","intent":"approve token for DEX swap","expectedFunction":"approve"}'

Payment & settlement details

Raw on-chain settlement parameters. AXON above handles these automatically through quote / test-buy / governed fetch.
