# Independence agent services API

Status: live paid pilot. Confirm the current 402 quote before payment.

POST /paid runs ContradictionCheck on 2–20 normalized JSON records.
POST /agent-critic/paid compares enumerated claims in another agent's answer with caller-supplied evidence excerpts. It does not authenticate sources or find omitted claims.
POST /prompt-risk/paid triages up to 10 supplied texts (60,000 characters total) for selected prompt-injection signals, returning per-item offsets without echoing the text. It cannot certify safety.
POST /output-judge/paid compares like-for-like enumerated claims from 2–5 agents against common supplied evidence. It does not authenticate sources or discover omitted claims.

PromptRisk has a free, deterministic input/output example at GET /examples/prompt-risk. A single small text starts at $0.01 over USDC; larger requests receive a higher quote, and card payment remains $0.50.
The same four services also have Base-USDC x402 routes under /x402 (for example, POST /x402/paid). MPP routes remain separate.
The OpenAPI contract at /openapi.json includes input examples and output schemas. In the live pilot, the 402 challenge is the authoritative quote; do not infer a fixed price from this page. The services do not authenticate sources, extract PDFs, or certify security. Live payment-to-delivery validation is still pending.
