Solana Account Snapshot

Call before pricing or settling a crypto payment: live spot prices for one or more coins by CoinGecko id (USD price, 24h change, market cap) from a keyless multi-source chain that never returns an upstream 429.

Call before adding or upgrading a dependency: package-registry metadata for one package (PyPI or npm): latest version, summary, license, dependency count; PyPI also returns 30-day downloads.

Call before trusting or paying a third-party x402 seller: catalog-vs-live integrity -- verify an x402 listing (payee, price, network, service, tags, bazaar block) against the live 402; an endpoint preflight for x402 catalog vs live offers, seller trust and listing consistency so an agent can skip dead or mismatched endpoints (JSON).

Call before routing or accepting an x402 payment: multi-rail health (facilitators, settlement, market) across x402 rails (JSON).

Generate a random UUID (uuid v4, RFC 9562) — 1..100 per call; format uuid|urn|hex|int.

Call before moving funds on Solana: decision-grade account snapshot — kind; mint decimals/supply/authority; whole-account balance and recent signatures — keyless solana-public-rpc.

Call before trading or pricing a Solana token: normalized live onchain snapshot (price, 24h change, liquidity, 24h volume, top DEX pair).

Validate, pretty-print (0-8 spaces), or minify JSON — json formatter/validator.

Difference between two ISO-8601 timestamps in days/seconds (date diff).

URL encode or decode a string (percent-encoding) for query, path or fragment.

EVM address checksum and validation — check an Ethereum/Base address format before sending funds.

Base58 encode or decode bytes/hex (Solana-style base58).

Base64 encode or decode a string — base64 encoder/decoder (body {mode:encode|decode,input}).

Hex encode or decode text — hex string encoder/decoder.

Decode a JWT — parse header and payload claims without a key (no signature verification).

SHA-256 hash/digest of a text string — also sha512 and sha3-256; returns hex.

Call before trusting or paying a third-party x402 seller: snapshot one listing from a fixed public directory (payapi, cdp, payai, bazaar) by its id/payTo, or pass ?since= to get told whether it changed since you last saw it. Reads public directories only - never a caller-supplied URL - and returns already-public fields (JSON).

World clock and timezone converter — convert timezones (timezone convert) for the current time or any instant (`at`) in IANA zones (`tzs`, e.g. Europe/London,Asia/Tokyo) or a fixed utc_offset (+05:30); returns local time, UTC offset, weekday and DST.

Validate an IBAN (international bank account number) — check the country, length and ISO 13616 mod-97 checksum; returns validity, country and check digits.

Call before onboarding, screening or paying a counterparty: full-text search of SEC EDGAR filings for an enforcement/regulatory phrase; returns matching filings (company, CIK, form, filed/period, state, SIC, accession + official sec.gov deep-link). Phrase search: quote your term, filter by form/date.

Call before moving funds on Solana: decision-grade account snapshot — kind; mint decimals/supply/authority; whole-account balance and recent signatures — keyless solana-public-rpc.
