by AgentFeed in Developer tools

x402 APIPassing, checked 23 min ago

Trial key: $0.25 of credit for the AgentFeed routes, for bots that can set an HTTP header but cannot pay x402 per call (n8n, Freqtrade, Hummingbot, scripts, gateways). Use when you need to answer: How can a bot that cannot pay x402 try AgentFeed for $0.25?

Example request

From the listing.

GET https://x402.ochinimus.app/api/keys/buy-trial

Parameters

ParameterTypeRequiredDescription
key_hashstringNosha256 hex (64 characters) of a key you generated yourself as afk_ + base58 of 32 random bytes: the server registers the hash and never sees the key
prefixstringNothe 8 characters after afk_ in that key, so /api/keys/balance can show it before the first use

Example response

The provider's example. We can't check it without paying.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.25.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://x402.ochinimus.app/api/keys/buy-trial'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - 'https://x402.ochinimus.app/api/keys/buy-trial' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
JavaScript: pay and call
// npm i @x402/fetch @x402/evm viem

// Pays at most $0.25 per call.
const client = new x402Client().setSpendControls({ maxAmountPerPayment: "$0.25" });
registerExactEvmScheme(client, { signer: privateKeyToAccount(process.env.EVM_PRIVATE_KEY) });
const pay = wrapFetchWithPayment(fetch, client);

// Not sure it's safe to pay? ToolVet checks it first for $0.005. Pay for that from a separate
