Machine-facing data, priced per call, paid over x402.
Faithful summaries and guaranteed-valid JSON extraction, $0.03 a call. For the agent that holds funds and nothing else — no accounts, no keys, no platform. Charged only when the result validates.
POST /v1/ai/summarize?length=short (body: the text, up to 24k chars)
→ { "summary": "...", "length": "short", "produced_at": "...", ... }
Information-dense, faithful to the text, no invented facts, no
“Here is a summary:” preamble. length=medium for
a paragraph or two.
POST /v1/ai/extract?fields=vendor,invoice_number,total,due_date
(body: the text)
→ { "data": { "vendor": "Meridian Office Supply Co.",
"invoice_number": "INV-4471",
"total": "$244.62",
"due_date": "October 3, 2026" },
"guarantee": "every requested field present; validated before charging" }
The guarantee is mechanical, not aspirational. Our server
parses the JSON and verifies every requested field is present —
null when the text does not contain it, never an invented
value — before you are charged. A call that cannot meet the
contract costs you nothing. A failed primary model retries once on a
different provider automatically.
POST /v1/ai/judge (body: {"criteria": "...", "deliverable": "...", "candidate_b": "..."?})
→ { "verdict": "pass", "score": 87, "reasons": [...],
"criteria_sha256": "...", "deliverable_sha256": "...",
"signature": { "algorithm": "Ed25519", ... },
"consistency": "identical inputs return this same verdict for 30 days" }Neither party to an agent-to-agent transaction can referee it — both have stakes. This is a verdict from a party with none, signed over the SHA-256 of the exact bytes judged, so either side can prove what the verdict was about. Identical inputs return the identical verdict for 30 days: verdict-shopping is impossible. Fix the criteria before the work with /v1/commit and the whole loop is dispute-proof.
Stated limits, in the response itself: a model-issued opinion, not ground truth or human review; resistant to — not provably immune from — instructions embedded in the material (which weigh against the work); and it says nothing about whether the criteria were fair. Honesty is what makes the signature worth anything.
An agent already running on a major platform should use its own model — it will be cheaper. The customer here is the agent with a funded wallet and no accounts anywhere: for it, three cents buys a capability it cannot otherwise reach.
