SignalWharf is a pay-per-request API returning deterministic signals obtained from publicly accessible website homepages. This is not a corporate registry, credit bureau, or verified source of revenue, employee count, legal status, or ownership information.
Protected requests use x402 payments in USDC. You must approve and sign each payment through your own compatible wallet software. Settlement is on-chain and generally irreversible. An attempted request can fail after a payment has been settled due to upstream failure; automatic refunds are not provided in this software version. Do not authorize payment if this risk is unacceptable.
Signals may be incomplete, inaccurate, outdated or blocked by website operators. Use for informational purposes, with independent verification before decisions. We do not guarantee uptime, availability, or fitness for any particular purpose.
Do not use the service for illegal targeting, harassment, unauthorized profiling, or violation of applicable law. Website content remains the property of its owners.
The endpoint processes the public domain supplied by the caller and performs outbound fetches to that website. Hosting infrastructure may retain operational logs. The service does not request personally identifiable information or manage private payment keys. Blockchain transfers may be publicly visible.
Template terms: before commercial launch, have a qualified professional review legal wording, privacy and consumer rights applicable to your jurisdiction.
