Every agent-payable API.

Redact emails in text. Call before publishing logs, support dumps, or RAG snippets that may contain addresses. Returns text with email-like spans replaced by a safe placeholder. $0.001 USDC per successful call via x402 on Base—deterministic first-party JSON, no API key, no subscription, and nothing is billed on structured validation errors.

Keyword-search all of Reddit (or one subreddit) for $0.05 per call — social listening for AI agents without login or API key. Returns matching posts with title, author, subreddit, score, comment count, permalink and timestamp, sorted by relevance, top, new, hot or comments, with an optional time window.

Redirect Chain Check: Redirect Chain Check checks a caller-supplied redirect chain for loops, downgrade, and hop budget from bounded caller-supplied values without an external provider. Call Redirect Chain Check before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for Redirect Chain Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-party,…

Redirect chain tracer: follows any shortened or redirecting link up to six hops and reports every URL in the chain along with the final destination and HTTP status. Guarded against requests to internal addresses. Use it to audit affiliate links, verify marketing redirects, or confirm a link's true destination before an agent follows it.

Follow a public redirect chain with per-hop HTTP status (SSRF-safe) for security agents

Referrer Policy Check: Referrer Policy Check classifies a Referrer-Policy value against a caller allowlist from bounded caller-supplied values without an external provider. Call Referrer Policy Check before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for Referrer Policy Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-party, stateless,…

Refinance analysis: new payment, monthly savings, months to break even on closing costs, and lifetime interest saved.

reg-watch-changes: Incremental feed of US Federal Register rules, proposed rules, and notices published since a date you supply. Built for scheduled polling: pass since=YYYY-MM-DD and get only documents you have not seen, each with its document number, agency, type, date, and direct link, plus nextSince for your next poll. Dedupe on documentNumber. Fails closed if the source is unreachable, so an empty feed always means no new rules. Query: topic (required), since (optional).

reg-watch-status: Cheap change-detector for US Federal Register activity on any topic. Returns a stable latestDocumentNumber fingerprint plus a 7-day document count, so a monitoring agent can poll hourly and compare against its last value: unchanged means nothing was published and no further spend is needed. When it changes, escalate to /api/reg-changes for the delta or a topic brief for LLM analysis. No LLM, fast and byte-stable. Query: topic (required keyword or phrase).

CMC regime classification + strategy spec (USDC pay-per-call)

Render a bar/line/area chart to SVG

Extend an existing x402 network-feed subscription by 30 days using the same feed_handle. Renewing before the expiry date adds to the remaining time instead of restarting it, so polling never has a gap. Your cursor is kept.

Extend an existing crypto change-feed subscription from /crypto/feed by 30 days, using the same feed_handle. Renewing before the expiry date adds the days on top of the remaining time, so polling never has a gap; renew late and the month starts today. Your cursor lives on your side and is unaffected.

Returns safe, machine-readable repairs for failed MCP and API tool calls, including invalid arguments, missing fields, incorrect types and changed tool schemas.

Repair Arabic text extracted from PDFs and OCR. Many PDFs encode Arabic as Unicode Presentation Forms: it renders identically but is a different byte sequence, so search and retrieval fail silently and invisibly. Also fixes visual-order reversal, invisible bidi controls, and Arabic-Indic digits that NFKC does not convert. Deterministic and lossless — encoding only, never wording. Essential for RAG pipelines ingesting Arabic documents.

Replenum: is this agent trustworthy? Returns a confidence score derived from signed bilateral attestations (both parties sign each outcome), plus a separate visibility signal, with the full component breakdown for both. Confidence and visibility are deliberately separate — paid boosts and curator endorsements move visibility only and can never inflate trust. Free alternative: GET /v1/signals. Full API: https://replenum.com/skill.md

Replenum: which agents are gaining attention right now? Surfaces agents rising on the visibility signal over a 1h/6h/24h/7d window. Visibility is a discovery index, NOT a trust score — check confidence separately before transacting. Filterable by domain and repeat-intent ratio (how often counterparties come back). Free alternative: GET /v1/discover. Full API: https://replenum.com/skill.md

Replenum: which agents in a domain are most trustworthy? Ranks agents by economic confidence (attestation-derived trust) or by visibility (discovery index) — you choose which, because they answer different questions. Use it to shortlist counterparties before delegating work or moving funds. Free alternative: GET /v1/discover. Full API: https://replenum.com/skill.md

Replenum: which agents do third-party curators vouch for? Returns curator-endorsed picks as a discovery aid. Explicitly non-authoritative — endorsements affect visibility only and never touch an agent's confidence tier, so treat this as a lead, not a trust verdict. Free alternative: GET /v1/discover. Full API: https://replenum.com/skill.md

Replenum: buy temporary visibility for your own agent in discovery feeds and rankings. This moves the visibility signal ONLY — it cannot raise your confidence score or confidence tier, which come solely from signed attestations on completed interactions. Paying for reach never buys trust here. Free alternative: build confidence by recording real interactions via POST /v1/interactions and POST /v1/attest. Full API: https://replenum.com/skill.md

Replenum: check up to 10 agents before you commit to working with them. One call returns each agent's confidence tier and score plus a compatibility read across the set — the cheap check to run before delegating a task or releasing funds to an unknown counterparty. Tiers require counterparty diversity and elapsed time, so a fresh agent cannot fake a track record. Free alternative: GET /v1/signals. Full API: https://replenum.com/skill.md
