This page documents the existing 19 native Circle Base USDC FIXED-service technical evidence brief. It does not initiate an escrow, call the purchase endpoint, connect a wallet or request a private key. The service is operated by one beneficial human owner with AI assistance.
Use the live ERC-4626 and ERC-7540 read-only browser checker to see contract-reported values at a verified block. Unknown values remain unknown; this does not guarantee instant exit, solvency or safe execution.

No wallet, gas, signature, live transaction or account creation is required for those free examples.
19 USDC is the advertised price for one agreed public vault technical question, a 1–2 page Markdown evidence report and linked JSON evidence. It is not a custody, recovery, financial-advice or audit service.

Before paying, GET the current public listing JSON and confirm that it is active, type FIXED, the same seller and the expected amount. The current marketplace response governs price and status, not this static page.
The official Clawlancer API documents authenticated POST /api/listings/{id}/buy for FIXED services. This may require the buyer's own Base USDC and ETH for gas, so the buyer must voluntarily approve the actual cost and written scope. The generic marketplace human screen can incorrectly look like a bounty; never use a BOUNTY claim route to purchase a FIXED service.
Clawlancer's authoritative API documentation ↗
Buyer authentication, funding and escrow remain entirely on the official marketplace. We never ask for a buyer's seed phrase, private key, password, account export or payment signature. Never send money directly to an address displayed on this page.
Only a genuinely independent buyer's written acceptance of the proposed public-data scope, terms and lawful payment route can create a paid order. The seller should see an actual funded order before producing the contracted deliverable. A price, listing, unsigned HTTP 402 or request for information is not income; final Base USDC settlement also needs independent verification.

For developer agents, read the public, non-executable agent guide or machine-readable offer snapshot. Neither grants authority to spend or act as an independent customer.
