claim_verdict

Submits a claim and returns a signed verdict: settled against real external ground truth (GitHub PR, on-chain tx, HTTP status, JSON field, Kalshi market, or multi-exchange price consensus), Ed25519-signed, hash-chained. Free tier -- no account, no card. Returns CONFIRMED, REFUTED, or ERROR -- never a forced guess.

distress_score

Validated corporate distress-foresight score for a single equity ticker: Altman Z-score computed from live SEC XBRL filings, backtested 71% sensitivity / 100% specificity with a ~109-day median lead time, Ed25519-signed. Paid: $0.15 USDC (Base) via x402 -- no free tier. A call without an attached x402 payment returns the payment requirement, not a verdict.

Argument	Type	Description
agent*	string	who is asking (shown on the public reputation ledger)
ticker*	string	equity ticker to score, e.g. "AAPL"

{
  "type": "object",

      "description": "equity ticker to score, e.g. \"AAPL\""
    }
  }
}

file_dispute

Files a bonded dispute against a verdict receipt: the disputed verdict is re-resolved immediately against the identical resolver specification that produced it -- independent re-run, not a re-vote. An upheld dispute overturns the verdict and queues a slashable payout against the notary's on-chain correctness bond. Paid: $1.00 USDC (Base) via x402 -- no free tier. A call without an attached x402 payment returns the payment requirement (price, payTo, asset), not a verdict.

Argument	Type	Description
agent*	string	who is filing the dispute (shown on the public reputation ledger)
receipt_hash*	string	the receipt_hash of the verdict being disputed -- must be under 48 hours old

Input schema (JSON)

{
  "type": "object",
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "required": [
    "agent",
    "receipt_hash"
  ],
  "properties": {
    "agent": {
      "type": "string",
      "description": "who is filing the dispute (shown on the public reputation ledger)"
    },
    "receipt_hash": {
      "type": "string",
      "description": "the receipt_hash of the verdict being disputed -- must be under 48 hours old"
    }
  }
}

screen_entity

OFAC SDN sanctions name screen: matches a legal name against the OFAC Specially Designated Nationals list, with a source_as_of freshness timestamp, Ed25519-signed. Paid: $0.001 USDC (Base) via x402 -- no free tier. A call without an attached x402 payment returns the payment requirement, not a verdict.

Argument	Type	Description
agent*	string	who is asking (shown on the public reputation ledger)
entity*	string	legal name to screen against the OFAC SDN list

Input schema (JSON)

{
  "type": "object",
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "required": [
    "agent",
    "entity"
  ],
  "properties": {
    "agent": {

      "description": "legal name to screen against the OFAC SDN list"
    }
  }
}

verify_receipt

Independently verifies any StillOS notary receipt by its hash: confirms the hash chain is intact and the Ed25519 signature is valid. Read-only, free, no auth.

Argument	Type	Description
hash*	string	the receipt_hash returned by claim_verdict or commit

Input schema (JSON)

{
  "type": "object",
