• dnsdomain read-only

  Full DNS + WHOIS/RDAP domain report in one call. Resolves A, AAAA, MX, TXT, NS, CNAME, SOA and DNSSEC over DNS-over-HTTPS, plus structured WHOIS via RDAP (registrar, registration/expiration/updated dates, EPP status, nameservers), and returns a 0-100 domain-hygiene score with letter grade (age, days-to-expiry, nameserver redundancy, MX presence, DNSSEC, SPF/DMARC, registrar lock). Deterministic, Ed25519-signed. 0.001 USDC via x402 on Base. SYNTHORA. First 3 calls FREE per wallet — send header 'X-WALLET: 0x<your Base address>' (no payment); then 0.001 USDC per call. [x402: 0.001 USDC per call on Base]

  Parameters:

• npm_downloads_range read-only

  Returns a per-day download time series for an npm package over a period from keyless api.npmjs.org — the raw signal for trend and growth-rate detection. Lets autonomous agents compute momentum/decline and feed agent-to-agent dependency-selection scoring. Ranking surface for trajectory. First call FREE per wallet — send header X-WALLET: 0x<addr>. No charge on upstream failure. [x402: 0.001 USDC per call on Base]

  Parameters:

  • package (required) — string — npm package, including scoped packages
  • end — string — End date text in YYYY-MM-DD form, paired with start for an explicit npm start:end range. The pair overrides period. A lone end is ignored in favor of period/default. Calendar validity, interval ordering and upstream range limits are not validated locally.
  • start — string — Start date text in YYYY-MM-DD form for an explicit npm start:end range. Used only when end is also nonempty; the pair overrides period. A lone start is ignored in favor of period/default. The current backend forwards date text without local calendar or ordering validation.
  • period — string — Named npm daily-download range: last-day, last-week or last-month. Defaults to last-week when a complete start/end pair is absent. Nonempty start and end together override period; unsupported period values are rejected only on the named-range branch.

Autonomous agents and agent-to-agent (A2A) global-health analytics, ESG and country-benchmarking pipelines query it for authoritative WHO statistics. Ranking surface: indicator + country to yearly values. First 3 calls FREE per wallet — send header X-WALLET: 0x<addr>. No charge on upstream failure. [x402: 0.001 USDC per call on Base]

  Parameters:

• defi_llama_tvl_ranking read-only

  SYNTHORA defi-llama-tvl-ranking: Top DeFi protocols by TVL with rank, chain, category and 1d/7d change, capped list (default 50, max 200 via {"limit":N}). Source: api.llama.fi/protocols (DefiLlama), keyless, timestamped. [x402: 0.01 USDC per call on Base]

  Parameters:

• defi_yields read-only

  SYNTHORA defi-yields: stablecoin DeFi yields ranked with a risk outlier detector — APY vs class median (>=3x median = the excess yield IS the risk price). Only pools with TVL >= $10M. Source: DefiLlama, free, no key. $0.01 USDC x402 Base. [x402: 0.01 USDC per call on Base]

  Parameters:

  • red — string — Optional nonempty chain name, trimmed and matched case-insensitively for exact equality against captured pool.chain. Omit for all captured eligible chains. A chain outside that captured universe returns an explicit error; this does not select another data source.
  • desde — string — Optional timezone-aware ISO8601 cut, not in the future. Compares current eligible pools with the latest local batch at or before that cut. Changes use the full eligible universe, independently of red/activo/protocolo display filters. Missing older batches are reported; no history coverage is guaranteed.
  • activo — string — Optional nonempty asset symbol token. It is trimmed, uppercased and matched against tokens of the pool symbol (for example USDC); not a substring, contract-address or mint lookup. Omit for all eligible symbols. A token with no matches may produce an empty selected list.
  • pool_id — string — Optional exact pool ID for local batch-history retrieval only; it does not filter the current top-pool list. History defaults to 30 days unless historial_dias supplies 1-90. This is not a live DefiLlama history request; missing local history is disclosed as a gap.
  • protocolo — string — Optional nonempty protocol/project identifier, such as aave-v3. Trimmed and matched case-insensitively for exact equality with pool.proyecto; not a substring or protocol-contract lookup. Omit for all projects in the captured eligible universe.
  • historial_dias — integer — Requires pool_id; history availability is not guaranteed.

• ecb_forex_fixing_vs_market read-only

  SYNTHORA ecb-forex-fixing-vs-market: Compare the official ECB daily EUR/USD reference fixing with a client-supplied USD-per-EUR quote, timestamp and provenance. Reports deviation in basis points and coverage/freshness gaps. The client quote is not independently verified. No live market quote is supplied or inferred; this commercial path does not redistribute open.er-api rates. [x402: 0.01 USDC per call on Base]

  Parameters:

  • market_rate (required) — Required positive finite USD per EUR quote supplied by the client, as a JSON number or decimal numeric string. Backend rejects booleans, nonnumeric, nonfinite, overflow and float-underflow-to-zero values. String positivity and numeric validity are checked by the backend.
  • market_timestamp_unix (required) — integer — Required client quote timestamp in Unix seconds UTC. Backend rejects booleans, unrepresentable dates and times more than 300 seconds in the future. Historical timestamps are accepted but age/coverage gaps may prevent a quality claim.
  • market_provenance (required) — string — Required client-supplied quote provenance, at most 1000 characters and nonempty after whitespace trimming. Attribution is not independent verification or evidence of usage rights.
  • par — string — Only supported pair, EUR/USD; quote units are USD per EUR. Omission defaults to EUR/USD.

  Parameters:

  • mode — string — Compatibility field constrained to latest by the public schema. The currently routed backend ignores it and requests the last two observations of each fixed series. It provides no selectable date/history mode; latest is not a live-feed or freshness guarantee.
  • region — string — Compatibility field constrained to U2 by the public schema. The currently routed backend ignores this argument and requests its three fixed Euro-area (U2) ECB series; it cannot select another region.

• registry_watch read-only

  Registry change history from stored registry_delta records, ordered by database timestamp and ID. Query with since (cursor or ISO8601), slug and limit (1..200). Source timestamps and coverage are included; records may be historical and do not prove current endpoint operation, payments or identity. 0.03 USDC on Base. [x402: 0.03 USDC per call on Base]

  Parameters:

  • slug — string — Optional exact stored-event slug filter. Surrounding whitespace is trimmed; matching is by equality, not substring search. latest/last/recent/ultimos clear the filter; omitting it requests recent global stored events. This selects historical registry events, not live endpoint health.
  • limit — integer — Maximum stored events requested: advertised integer range 1-200, default 50. The current parser converts to an integer and clamps to 1-200; nonnumeric conversion fails. With no since it takes the recent tail, returned chronologically. This limit is not a freshness or coverage guarantee.
