x402 Utility APIs for AI Agents — ForgeMesh Utility Grid

Endpoints (340 live)

• POST /knowledge-lookup — Encyclopedia summary API: the lead summary of any English-language encyclopedia article — title, one-line description, extract paragraph, thumbnail, and canonical URL — as JSON. For entity enrichment, fact grounding, and knowledge agents. CC BY-SA content with attribution included. (0.003 USDC on Base)
• POST /is-site-up — Website uptime check API: status code, response time in ms, and key headers for any URL in one call. The heartbeat probe monitoring agents schedule every few minutes. (0.002 USDC on Base)
• POST /metric-imperial-convert — Metric-imperial conversion API: miles↔km, lb↔kg, °F↔°C, gallons↔liters and 100+ more units, one call, exact factors. Deterministic and auditable — cheaper than burning reasoning tokens, zero arithmetic-hallucination risk, and the result can be cited. (0.001 USDC on Base)
• POST /resolve-dns — DNS resolver: query A, AAAA, MX, TXT, NS, CNAME, SOA, CAA, or SRV records for any hostname and get the validated answer section — name, type, TTL, data — as JSON. Ask it things like "what are example.com's MX records" or "does this domain have a CAA record." For infrastructure checks, email deliverability, and domain verification agents. (0.003 USDC on Base)
• POST /email-validate — Check whether an email address is well-formed and its domain can actually receive mail — RFC-style syntax check plus a live MX (falling back to A) lookup — returning the parsed domain, sorted mail hosts, and a deliverable flag. Answers "is this email address real" and "will mail sent here bounce" without probing the mailbox itself. Use for lead cleaning, signup validation, and contact verification. Nothing stored. (0.003 USDC on Base)
• POST /weather-forecast — Weather forecast API: current conditions (temperature, feels-like, humidity, wind, weather code) plus a 3-day daily forecast (highs, lows, precipitation probability) for any latitude/longitude worldwide, as structured JSON. Use for travel planning, logistics, event scheduling, and assistant agents. Cached 10 minutes. (0.005 USDC on Base)
• POST /endpoint-of-the-day — Endpoint-of-the-day picker for the ForgeMesh x402 fleet: every UTC day one of 500+ paid routes across 11 services is featured with its price, description, input schema, example output, and payment instructions. Rotation is deterministic — no randomness, no repeats until the whole pool has had its day. Optional date (YYYY-MM-DD) to preview a specific day's pick. (0.001 USDC on Base)
• POST /current-time — Current time API: the time right now in any IANA timezone (America/Chicago, Asia/Tokyo...) — local ISO timestamp, UTC ISO, unix epoch, human-readable string, and day of week. The sanity check every scheduling, logging, and coordination agent needs. Deterministic and instant. (0.001 USDC on Base)
• POST /vin-decode — VIN decoder API: turn any 17-character vehicle identification number into structured specs — make, model, year, trim, body class, engine (cylinders, displacement, horsepower, fuel), transmission, drive type, doors, GVWR, and assembly plant. Handles partial VINs with * wildcards. Official registration-grade decode for automotive, insurance, dealer, and marketplace agents. Response includes affiliate offers for full VIN history reports. (0.005 USDC on Base)
• POST /random-token-generator — Produces random hex strings or alphanumeric secrets, 8 to 128 characters, from OS-grade entropy, alongside batch UUID generation, none of it logged or retained. Useful for session tokens, temporary passwords, API credential material, and one-time codes where true randomness matters more than a pattern an LLM might repeat. (0.001 USDC on Base)
• POST /lobbying-filings — Lobbying disclosure filings: who is lobbying the US federal government, for whom, and on what — quarterly registrations and reports with client, lobbying firm, income or expenses, specific issues text, and the individual lobbyists named on each filing. Filter by client company, lobbying firm, or year. Follow-the-influence data for policy, market-intel, and accountability agents. (0.01 USDC on Base)
• POST /crontab-next-run-time — Parses any standard cron expression and computes its next 1-20 firing times in a chosen timezone, flagging malformed expressions clearly rather than letting a bad schedule silently fail in production. For scheduler tooling, CI pipelines, and agents that generate cron syntax and need to sanity-check it. (0.002 USDC on Base)
• POST /text-to-speech — Text-to-speech API: convert up to 2000 characters into natural speech (WAV, base64) using our locally-hosted neural speech engine — no API keys, pay per call with USDC. Choose voices F1-F5/M1-M5. Use for voice agents, notifications, audio content, and IVR. Text never stored. Full 20-voice / 31-language tiered product at voice.forgemesh.io. (0.01 USDC on Base)
• POST /whois-lookup — WHOIS-style registration lookup: created/updated/expiry dates, registrar, status codes, and nameservers for any domain, normalized from the authoritative registry into JSON. For "who owns this domain," availability checks, expiry monitoring, and security-screening agents. (0.005 USDC on Base)
• POST /qr-code-image — Generates a ready-to-embed QR code image, base64 PNG, from any text or URL input up to 2000 characters, with configurable dimensions and error-correction level. A drop-in way for ticketing systems, packaging, and signage pipelines to produce scannable codes without installing a QR library or maintaining rendering code. (0.003 USDC on Base)
• POST /mp4-to-mp3 — MP4 to MP3 API: extract the audio track from any public video URL as an MP3 (192k), on our own hardware. 25MB input cap. Use before transcription or for audio archiving. Files deleted after processing. (0.005 USDC on Base)
• POST /qr-code — QR code generator: turn any text or URL (up to 2000 characters) into a scannable PNG QR code, generated on our own hardware in milliseconds, returned base64. Answers "make me a QR code for this link." Set size 128-1024px. For payment links, tickets, onboarding flows, and print pipelines. (0.003 USDC on Base)
• POST /speech-generator — Speech audio generator: reads any block of text aloud and returns the result as a downloadable WAV file, selectable across ten built-in voice presets. Pay-per-call with no subscription or stored text. Useful for narrating short-form content, generating spoken alerts, or producing sample audio for voice-agent testing. (0.01 USDC on Base)
• POST /transcribe — Audio transcription API: transcribe any public audio URL (mp3, wav, m4a, ogg — up to 25MB / ~20 min) to text with a neural speech-recognition engine running locally on our hardware. Multilingual (~99 languages), auto language detection. Use as a speech-to-text step for voicemail, podcasts, meetings, and voice agents. Audio is processed in a sandbox and deleted immediately; we keep nothing. (0.03 USDC on Base)
• POST /agent-fortune — Agent fortune API: a fortune cookie written specifically for AI agents ('A cached response is worth two upstream calls'), plus a lucky number and lucky HTTP status code. The cheapest, most delightful way to make your first x402 payment and verify your wallet stack works end to end. New fortune every call. (0.001 USDC on Base)
