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
A JSON object containing: a status field (quoted, ready, needs_input, blocked, unknown, unsupported, or unavailable), a priceUsd field always set to '0' (this lookup is free), a markdown-formatted guide with the matched API contract, pricing breakdown, prerequisites, and next steps, and a guideUrl pointing to the wallet-free advisor endpoint for further planning.
Example use cases
Budget check before autonomous batch job
“I want to run 1000 API calls to enrich company data using ReallyBigMagnet, but I need to know the exact cost and contract terms first — my total budget is $50 USD and I'll be paying with x402. Can you get me a free quote before I commit to anything?”
Wallet-free planning for a new agent
“My agent doesn't have a crypto wallet yet — can you look up what it would take to use the ReallyBigMagnet seller API to send 200 SMS messages, and tell me the prerequisites and next steps without actually buying anything?”
Comparing payment options for a recurring task
“I'm trying to decide whether to pay by card or x402 for a recurring ReallyBigMagnet API job that scrapes product prices daily — can you get me a free quote showing both options and what the contract looks like?”
Technical details
Endpoint
POSThttps://agents.reallybigmagnet.com/zeroclick/agent/quote?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to plan or cost-check a ReallyBigMagnet API task before committing any funds — especially if you don't yet have a wallet or payment method set up. It is the right first step for any autonomous agent workflow on this platform, as it provides the exact contract, price, and prerequisites needed to proceed. Prefer it over /zeroclick/agent/guide when you want a structured, parseable JSON response rather than pure markdown guidance.
Side effects
- Missing required 'goal' field returns a validation error
- Goal description too vague may result in status 'needs_input' with clarifying questions
- Unsupported task type returns status 'unsupported'
- Service temporarily unavailable returns status 'unavailable'
- Malformed budgetUsd pattern (e.g. non-numeric) causes schema validation failure
- Quantity outside 1–1,000,000 range rejected by schema validation
