How this service works
High-speed API suite for AI processing, web scraping, and smart data utilities across 57+ blockchain networks. Pay-per-call via x402.
Output
Returns a JSON-RPC response object containing the result of the requested humanity-related method call, such as verification status, credential data, or registry lookup results for the queried blockchain address or entity.
Example use cases
Verify wallet humanity before airdrop
“Before we distribute the airdrop, check if wallet 0x1234...abcd is registered as a verified human on the humanity protocol so we can exclude bots.”
On-chain humanity proof for DeFi access
“Query the humanity RPC to see if address 0xDEAD...BEEF has a valid proof-of-humanity credential — use the getHumanityProof method.”
Batch human status check for governance
“I need to verify that 0xAAAA...1111 is a confirmed human participant on-chain before counting their governance vote — look up their humanity status via the RPC.”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/humanity/rpc?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to query humanity/proof-of-personhood data directly via a JSON-RPC interface on a blockchain network, especially when integrating with the Synapse API's pay-per-call x402 micropayment model. Prefer this over generic blockchain RPC providers when specifically querying humanity protocol data.

- Malformed params array causes invalid params error
- Unpaid or failed x402 payment returns 402 Payment Required
- Unsupported network or address format returns an error
- Rate limiting or quota exhaustion returns 429 or similar
