How this service works
Synthex Forge x402 Receive: 41 paid verification, attestation and governance endpoints (Ed25519 + SHA-256 signed artifacts) plus free verify/public-key/standard sibling routes. Paid routes answer HTTP 402 with an x402 v2 `payment-required` envelope (atomic USDC on Base mainnet, chain ID 8453). Free routes are declared with `security: []` per the x402scan discovery spec.
Output
Returns a JSON object with an 'ok' boolean indicating whether the reputation computation and attestation were accepted. The full signed artifact (Ed25519 + SHA-256) reflects the aggregated outcome history for the submitted agent identifier.
Example use cases
Pre-delegation agent trust check
“Before I hand off this data processing job to agent DID:key:z6Mk... can you run a reputation assessment on it using its last 5 outcome events — two successes at $30 each, one failure at $15, and two disputes at $40 each — so I know if it's trustworthy?”
Multi-agent marketplace vetting
“I need to vet a contractor agent with service key did:web:agentx.example.com for our marketplace. Score its reputation from these signed events: three successes totaling $200 and one dispute for $75 flagged last month.”
Post-task governance attestation
“Submit a reputation update for agent wallet 0xDEF456 — it just completed a task successfully for $120, and I want that outcome recorded in its reputation history with a note saying 'invoice automation completed on time'.”
Technical details
Endpoint
POSThttps://x402.synthexforge.com/v1/agent-reputation?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need cryptographically attested agent reputation scoring backed by Ed25519 signatures and SHA-256 artifacts, particularly for governance workflows in multi-agent systems operating on Base mainnet. It is ideal when you need on-chain-adjacent trust signals for agent wallets or DIDs, rather than simple self-reported metrics or centralized reputation databases.
Side effects
- Payment not provided or invalid — returns HTTP 402 with x402 v2 payment-required envelope specifying USDC on Base mainnet (chain ID 8453)
- Malformed agent identifier — returns error if wallet/DID/service key is not recognizable
- Invalid or unsigned outcome events — rejected if event structure does not conform to expected schema
- Missing required fields (agent or events array) — returns validation error
- Network or signing key issues on provider side — may return 5xx
