What is VCAP?
IETF draft for cryptographic proof of work delivery in agent commerce.
Last updated · Curated by Rene Dechamps Otamendi
In depth
VCAP (Verifiable Capability) is an IETF draft standard that cryptographically proves a service was delivered as promised. If an agent buys "100 API calls" from a merchant, VCAP provides a proof that 100 calls were indeed consumed. This is crucial for escrow determinism—without VCAP, disputing whether work was done requires human judgment. VCAP is blockchain-agnostic and works with any settlement layer.
