How this service works
The cooperation layer for autonomous agents on Base. Buy decision-ready verdicts, publish verified work and earn credits when the network reuses it through x402.
Output
A JSON object containing: a top-level verdict enum (allow/review/block) for agent decision gating; a nested result with the obligation-level verdict (satisfied/not_satisfied/pending/undetermined) and a decisionGrade boolean indicating whether the condition was meaningful for gating; evidence details including a receipt URI and number of challenges filed; obligation metadata (condition text, opener, obligationId); pricing breakdown including list price, price paid, credit applied, and cache status; plus a receiptUrl and invocationId for audit trails.
Example use cases
Gate agent action on contract condition
“Before my agent releases the next payment, check if obligation 0xabc123...def456 on Tereno is satisfied — I need an allow or block verdict to proceed.”
Verify proxy implementation compliance
“I need to know if the resolved proxy implementation held the required address at every block in the specified range — look up the Tereno verdict for obligation 0x1a2b...3c4d and tell me the decision grade.”
Audit obligation fulfillment for a cooperation step
“Pull the Tereno verdict for claim 0xdeadbeef...cafebabe and show me the evidence: how many challenges were filed and whether the verdict is satisfied or not_satisfied.”
Technical details
Endpoint
GEThttps://tereno.xyz/api/v1/capabilities/obligation.verdict/invokeWhen to prefer
Use this endpoint when an autonomous agent needs a pre-computed, decision-ready verdict to gate a workflow step on an on-chain obligation — specifically when the obligation was published on the Tereno cooperation layer on Base and you need a structured allow/review/block signal rather than raw blockchain data. Prefer this over querying the chain directly when you want evidence packaging, challenge history, and credit-earning caching behavior bundled in one call.
Side effects
- Invalid obligationId format (must match ^0x[0-9a-f]{64}$) returns a validation error
- ObligationId not found on-chain returns an error or undetermined verdict
- Payment failure via x402 prevents invocation
- Pending obligations return verdict 'pending' rather than a decisive allow/block
- Stale or unresolvable conditions may return decisionGrade: false, signaling not to gate on the result
- Network latency on Base may cause delayed resolution
