Every agent-payable API.

Verify up to 100 emails in one call; returns a per-email record matching /verify.

Generate a QR code from text as PNG (base64) or SVG. Custom module size, quiet-zone margin, and hex colours. Deterministic, capacity-capped at 2953 bytes. Set delivery to "url" to receive a short-lived download link instead of inline data.

Rerank candidate texts against a query with a cross-encoder (ms-marco-MiniLM-L-6-v2): joint query+document scoring, much sharper than cosine similarity over embeddings. Returns ranked indices with 0-1 relevance scores. Up to 64 texts per call. Pairs with /embed for a recall-then-precision RAG pipeline.

Buy ONE exclusive off-market seller lead: the single highest-scored available lead (optionally filtered by county or lead_type). Once you buy it, it is permanently removed from the shared /api/leads pool and never sold to anyone else — yours alone. Same fields as the shared feed: address, distress signal verified <7 days, 0-100 lead_score with itemized rationale, public-record source URL.

Buy the "My Agent Bought Me This" embroidered hat — 0.5 USDC on Base

Buyer-side payment firewall: should THIS agent make THIS payment now? Where /api/assess vets the seller, this vets the payment against your own agent's behaviour.
