Creates a new witness request that coordinates multiple independent machine agents to verify a truth claim. Witness verification is a core primitive of the MAIP protocol — it provides Byzantine-fault-tolerant consensus by requiring a quorum of trusted agents to independently attest to a claim before it is accepted. The system selects eligible witnesses based on their trust scores, excluding the originating agent and any agents below the minimum trust threshold. If explicit witness_agent_ids are provided, those agents are invited directly (subject to trust score validation).

​
Authentication

Requires X-API-Key header or Bearer JWT token. Tenant-scoped via X-Tenant-ID.

​
Request Body

​
claim_id
string
required
The identifier of the truth claim to be witnessed. Must reference an existing claim in pending or verifying status. Format: maip-tc:ULID.
​
required_witnesses
integer
default:"3"
The number of witness attestations required to reach consensus. Minimum: 1. Maximum: 10. Higher values increase verification confidence but take longer.
​
witness_agent_ids
string[]
Optional list of specific agent identifiers to invite as witnesses. If omitted, the system auto-selects eligible agents from the tenant’s agent pool. Format: maip-agent:ULID.
​
min_trust_score
number
default:"0.5"
Minimum trust score required for an agent to participate as a witness. Range: 0.0-1.0. Agents below this threshold are excluded from selection.
​
ttl_seconds
integer
default:"86400"
Time-to-live in seconds before the witness request expires if consensus is not reached. Range: 300 (5 minutes) to 604800 (7 days).

​
Response

​
id
string
Unique identifier for the witness request. Format: maip-wit:ULID.
​
claim_id
string
The truth claim being witnessed.
​
status
string
Initial status of the witness request. Always pending on creation.
​
required_witnesses
integer
Number of attestations needed to reach consensus.
​
current_witnesses
integer
Number of attestations received so far. 0 on creation.
​
expires_at
string
ISO 8601 timestamp when the witness request will expire if consensus is not reached.
​
created_at
string
ISO 8601 timestamp of creation.
