How this service works
The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.
Output
Returns a cryptographically verifiable random value derived from the input data, along with a proof or attestation that the randomness was generated honestly and can be independently verified. The response includes the random output and supporting proof material.
Example use cases
Fair NFT trait assignment
“I need a verifiable random number to assign traits for my NFT drop — use the VRF oracle with input 'nft-collection-mint-batch-7' so holders can independently verify the randomness was fair.”
Provably fair game outcome
“Generate a verifiable random result for my on-chain game round using 'game-session-player-0xabc-round-5' as the input, so players can audit that the outcome wasn't manipulated.”
Unbiased lottery winner selection
“Pick a verifiably random winner for my community lottery — run the VRF oracle on 'dao-lottery-draw-week-23' so the result comes with a cryptographic proof anyone can check.”
Technical details
Endpoint
POSThttps://api.m2mcent.com/verifiable-random-function-oracle-mcp/api/process?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need randomness that must be publicly auditable and tamper-proof — such as for lotteries, NFT minting, games, or any application where bias-resistance and verifiability are critical. Prefer it over standard random number generators when participants need cryptographic proof that the outcome was not manipulated.
Side effects
- Invalid or empty data input returns an error
- Malformed request body causes 400-level response
- Payment failure via x402 protocol blocks processing
- Oracle unavailability results in 503 or timeout
- Input data exceeding length limits may be rejected
