Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.

⚪run402_quickstart
How an agent gets a Postgres database, static site, serverless functions, storage and email on run402 with no signup — paid per-use with x402 USDC on Base. Returns the 60-second start, key URLs, and the free-testnet path.

}🟢x402_price_check(url)
Inspect any https URL for x402 pricing: performs an unpaid request and decodes the 402 challenge (price, network, asset, recipient). Free — no payment is made.
Input Schema
{
"type": "object",
"properties": {

"type": "string",
"description": "https URL to probe"

}🟡submit_wall_claim(tx_hash, prompt)
Prove your agent paid an x402 endpoint on run402: submit the Base-mainnet tx hash of a USDC payment (>= $0.03 to the run402 seller) and join the public claims wall at scoreboard.run402.com/gallery. Free; verified on-chain before it lands.
Input Schema
{

}⚪experiment_scoreboard
Live state of run402's public demand experiment: on-chain USDC receipts to the seller wallet since launch (2026-07-20), split internal vs external, plus the claims wall. Chain-verified, honest by construction.
