price-feed

paidFetch handles the 402 challenge automatically. You get the upstream response plus an on-chain receipt. No retry loop to write yourself.

import { paidFetch } from '@chest-gate/sdk'

const { body } = await paidFetch(
  'https://gate.chest.sh/g/price-feed/<endpoint>',
)

console.log(body)

First time? Top up your chest.sh wallet, or follow the quickstart.

If you ship an agent, MCP server, or skill that calls price-feed, you keep the referrer share on every paid call. Your cut lands in the wallet you’ve set, the same block the merchant gets paid.

import { paidFetch } from '@chest-gate/sdk'

const { body } = await paidFetch(
  'https://gate.chest.sh/g/price-feed/<endpoint>',
  { appSlug: 'your-app' },
)

Publish an app once; chest.sh resolves your payout wallet from the app manifest on every call.
