How this service works
Describe your task to get the matching API contract, prices, prerequisites and next steps. This is a $0 wallet-proof lookup, not the seller's paid service. No purchase is executed. Without a wallet, use /zeroclick/agent/guide.
Output
Returns a JSON object with: a `status` field (e.g. 'quoted', 'ready', 'needs_input', 'blocked'), a `priceUsd` always equal to '0' (this lookup is always free), a `guide` field containing Markdown with the matched API contract, exact pricing, prerequisites, and next steps, and a `guideUrl` pointing to a wallet-free advisor endpoint for further planning or recovery.
Example use cases
Pre-purchase API cost discovery
“Before committing any money, can you find out how much it costs and what's required to query insane-deal award alerts on ZeroClick for economy-class routes — I'm planning about 100 calls and have a $15 budget?”
Autonomous agent setup guidance
“I'm building a no-human-in-the-loop agent that monitors award deals. Can you pull the free quote and setup guide for the ZeroClick deal query API so I know the exact contract, pricing, and how to authenticate autonomously?”
Budget-constrained API planning
“I only have $5 to spend. Can you get a free quote from ZeroClick showing which award-deal API operations I can afford, what they cost per call, and what the next steps are to get started?”
Technical details
Endpoint
POSThttps://zeroclass.pay.zeroclick.io/zeroclick/agent/quote?utm_source=zero.xyzWhen to prefer
Use this endpoint before making any paid API call on zeroclass.pay.zeroclick.io to understand exact pricing, prerequisites, payment methods, and next steps at zero cost and without needing a wallet. Prefer this over direct paid endpoints when you are planning, budgeting, or onboarding — especially in autonomous or low-human-oversight contexts where knowing the contract upfront prevents unexpected charges.
